Q. Which sleep-related code codes do not require prior approval and/or notification?

A. The UnitedHealthcare Community Plan does not require prior approval and/or prior notice for unsupervised home sleep tests. CPT codes are 95800, 95801, 95806 and HCPCS codes are G0398, G0399 and G0400.

Billing and encoding policies

B. The polysomnography/sleep study must be performed with the intention of completing the study with positive airway pressure (PAP) titration, ie H. Code CPT 95811. Code CPT 95810 is only permitted if the study of the sleep did not show events consistent with sleep apnea or sleep apnea. PAP titration cannot be completed due to unforeseen reasons as documented in the polysomnography report. Examples include, but are not limited to, the following:

1. Total time I am insufficient;

2. Criteria for obstructive sleep apnea were met at the end of the study, with insufficient sleep time remaining for continuous positive airway pressure (CPAP) titration;

3. Attempted CPAP but not tolerated by the patient.

C. A polysomnogram/sleep study will be performed every five years unless there is a significant change in the patient's condition. A repeat polysomnography five years ago is adopted for the following indications:

1. Weight gain or loss of ten percent of body weight;

2. After surgical or oral device treatment of patients with moderate to severe OSA;

3. When clinical response is insufficient or when symptoms recur despite an initial good response to PAP treatment.

4. Follow-up PAP titration study if indicated and failure to complete the split overnight sleep study as in II.B.

D. Various sleep latency tests (CPT code 95805) are adopted for the evaluation of patients with suspected narcolepsy to confirm the diagnosis.

E. Other measurements taken during a sleep study (eg, vital signs, muscle activity, oximetry, airflow, blood gases, penile engorgement, gastroesophageal reflux) are also an integral part of the Service and will not be paid for separately.

F. CPT code 95810 is covered only as mentioned above (II.B.).

G. Polysomnography/Sleep Studies are only covered once every five years, except as noted above (II.C).

Special Considerations 1 Pre-certification with review by a Medical Director or designee is required for supervised/laboratory sleep testing (LST), CPT codes 95805, 95807, 95808, 95810 and 95811. Pre-certification is not required for sleep testing. unsupervised/domestic sleep (HST); CPT codes 95800, 95801, 95806 and HCPCS codes G0398, G0399, G0400.

2 Actigraphy as a stand-alone test (code CPT 95803) is not clinically required and requires review by the Medical Director.

3 Pre-certification is required for services covered by the member's general benefits package when performed at a participating provider's office. Pre-certification is not required for commercial plans, but is recommended for out-of-network services provided at the office and covered by the member's general benefits package. If pre-certification is not obtained, Oxford may assess medical need after service is provided.

sleep studies at home

Home Sleep Studies (HSS) may be considered medically necessary if, in the treating physician's opinion, they are clinically indicated. A second home sleep study may be indicated to assess the impact of uvulopathopharyngoplasty (UPPP) or other corrective surgery for OSA after adequate recovery from surgery

The following contraindications apply only to home sleep studies. A home sleep study performed in the presence of any of the following contraindications is not a covered benefit. If the patient meets the criteria for a PSG but has any of the contraindications listed below, an institution-based PSG will be approved.

1. Moderate or severe chronic obstructive pulmonary disease (COPD) - FEV1/FVC less than or equal to 0.7 and FEV1 less than 80% predicted
2. Moderate or severe congestive heart failure (CHF) - NYHA Class III or IV
3. Cognitive impairment (inability to follow simple instructions)
4. Neuromuscular impairment
5. Suspected sleep disorder other than OSA (eg, central sleep apnea, narcolepsy, restless legs syndrome, circadian rhythm disorder, parasomnias, periodic limb movement disorder)
6. Previous technically suboptimal home sleep study (attempted 2-night study)
7. Previous 2-night home sleep study without an OSA diagnosis in a patient with ongoing clinical suspicion of OSA
8. The patient is being deprived of oxygen for any reason
9. History of cerebrovascular accident (CVA) in the last 30 days
10. History of ventricular fibrillation or sustained ventricular tachycardia

CPT 95807 Sleep study, simultaneous recording of ventilation, respiratory effort, ECG or heart rate and oxygen saturation, accompanied by a technician

diagnosed

All reasonable and necessary diagnostic tests performed by sleep disorder clinics (sleep disorder centers or sleep-related breathing disorders laboratories) for the conditions listed in the Indications section below are covered if the following criteria are met:

  • The clinic is attached to a hospital or is under the direction and control of physicians. Diagnostic tests that are routinely performed in sleep disorders clinics may also be covered without a doctor's direct supervision.
  • Patients are referred to the Sleep Disorders Clinic by the attending physician, and the clinic maintains a record of the attending physician's instructions.
  • The need for diagnostic tests is supported by medical evidence, e.g. B. Confirmed medical tests and laboratory tests.



Diagnostic tests that duplicate prior tests performed by the treating physician to the extent that the prior test results are still relevant to the patient's condition are not covered as Section 1862(a)(1)(A) unreasonable and required) of the Social Security Act (the Act). Documentation of previous test results should be maintained in the patient's record.

Therapeutic Services

Therapeutic services may be accepted if they are customary and recognised, reasonable and necessary for the patient, provided in a hospital as an inpatient or outpatient or in an independent facility and under the direct personal supervision of a physician.



Certification Requirements

If the above testing is performed at an independent facility (including sleep clinics that are part of a physician's office, independent diagnostic testing facilities (IDTFs), and any other non-hospital facility that conducts sleep studies), the facility must have on file and make available to Medicare, upon request, evidence that:

  • They are fully or provisionally certified by the American Academy of Sleep Medicine (AASM) as a sleep disorders center or laboratory for sleep-disordered breathing, or by the Joint Commission as an autonomous sleep center, or accredited as an independent provider of sleep testing services by the Accreditation Commission for Health Care, Inc.
  • Facility certification is required when global, professional, or technical components are billed for a physician's office, IDTF, and any other non-hospital facility.
  • Effective date of this requirement: January 1, 2011.





Indications of coverage, limitations and/or medical necessity


Sleep studies and polysomnography (PSG) refers to the continuous and simultaneous monitoring and recording of various physiological and pathophysiological parameters of sleep provided in a sleep laboratory facility, including review, interpretation and medical reports. A technician is physically present to monitor the recording during the sleep period and can intervene if necessary. Studies are conducted to diagnose a variety of sleep disorders and to assess a patient's response to therapies such as CPAP (continuous positive airway pressure). PSG differs from sleep studies by including sleep staging.



Sleep disorders clinics are facilities where specific disorders are diagnosed through sleep testing. These clinics are used for diagnosis, therapy and research. Sleep disorder clinics may offer some Medicare-covered diagnostic or therapeutic services. These clinics may be affiliated with a hospital or a stand-alone facility. Regardless of whether the clinic is a hospital or an independent clinic, reimbursement for diagnostic services may be subject to different legal requirements than reimbursement for therapeutic services.


tips

Diagnostic tests are covered only if the patient has symptoms or signs of any of the following conditions:

  • Narcolepsy:Associated diagnostic tests are covered if the patient has episodes or attacks of inappropriate sleep, amnesic episodes, or persistent and disabling drowsiness.
  • sleep apnea:The nature of apneic episodes can be documented by appropriate diagnostic tests.
  • Parasonias:The suspicion of seizure disorders as a possible cause of the parasomnia is adequately assessed by standard or prolonged sleep EEG studies. In cases where seizure disorders have been ruled out and in cases where there is a history of repeated violent or painful episodes during sleep, polysomnography may be useful in providing a diagnostic or prognostic classification.



Polysomnography is indicated to provide a diagnostic or prognostic classification when all of the following are present:

  • When clinical judgment and standard EEG results (if available) do not determine that the nocturnal events are due to a seizure disorder.
  • In cases where there is a history of repeated violence or painful episodes during sleep.
  • Patients are evaluated for sleep patterns suggestive of unusual or atypical parasomnias due to:
    • The patient's age at onset.
    • The time, duration, or frequency of occurrence of the behavior.
    • The specifics of each motor pattern are questionable (e.g., stereotyped, repetitive, or focal).

When polysomnography is done to diagnose parasomnias, the following measurements are usually obtained:

  • Sleep assessment channels (EEG, EOG, chin EMG).
  • EEG with an extended bilateral mount.
  • EMG for body movements.
  • Audiovisual recording and observations documented by technicians.



diagnosis of obstructive sleep apnea (OSA), pending prescriptionContinuous positive airway pressure (CPAP) is covered when performed with a Medicare-approved device (see NCD 240.4.1).

Other indications and restrictions



Split-Night-Studien

For CPAP titration, a split-night study (first diagnostic polysomnography followed by CPAP titration during same-night polysomnography) is an alternative to a full night of diagnostic polysomnography followed by a second night of titration if the following criteria are met:

  • However, a respiratory disturbance index (RDI) ≥ 15 or RDI ≥ 5 and < 15 should be based on at least two hours of sleep recorded by polysomnography using actual hours of sleep recorded. It is known that a split study may underestimate the severity of sleep apnea. However, an AHI of 40 is considered severe OSA with known mortality, and additional testing during the rest of the night is unlikely to change the need for treatment.
  • CPAP titration is performed for more than three hours.
  • The entire midnight study must include six or more hours of sleep parameter recording and must be billed as a single unit of 95811.

follow-up studies

A follow-up polysomnogram or cardiorespiratory sleep study is indicated for the following conditions:

  • Assessment of response to treatment (CPAP, oral devices, or surgical procedures).
  • After significant weight loss has occurred in patients on CPAP for the treatment of sleep-disordered breathing, to determine whether CPAP is still required at the previously titrated pressure.
  • After significant weight gain in patients previously successfully treated with CPAP who are symptomatic again despite continued use of CPAP to determine if pressure adjustments are necessary.
  • When the clinical response is inadequate or when symptoms recur despite an initial good response to CPAP treatment.



sleep test at home

Home Sleep Testing Medical Services (G0398, G0399 and G0400) are covered for the purpose of examining a patient to diagnose obstructive sleep apnea if home sleep testing is appropriate and necessary to diagnose the patient's condition and meet the all eligibility requirements other Medicare requirements, including use of an approved device, and the physician performing the service has sufficient training and experience to reliably perform the service.

The physician providing the service must meet one of the following requirements:

  • The doctor is a diplomat of the American Board of Sleep Medicine (ABSM).
  • The doctor is a diplomat in sleep medicine and a member of the American Board of Medical Specialties (ABMS).
  • The physician is an active employee of one of the accredited sleep centers or laboratoriesamericano Academiaof Sleep Medicine (AASM) ou The Joint Commission (ehemals Joint Commission on Accreditation of Healthcare Organizations (JCAHO)).



A home sleep test is only covered when performed in conjunction with a comprehensive sleep assessment and in patients with a high pre-test probability of moderate to severe obstructive sleep apnoea. The home sleep test is not covered for people with comorbid conditions (moderate to severe lung disease, neuromuscular disease, or congestive heart failure), other sleep disorders (central sleep apnea, periodic limb movement disorder, insomnia, parasomnias, circadian rhythm or narcolepsy), or for screening asymptomatic people.



interpretations

These recordings should be interpreted by a physician or physician with appropriate training in sleep medicine and significant experience in interpreting standard polysomnograms.



Restrictions:

Contractors consider a service appropriate and necessary if they determine that the service:

  • Safe and effective.
  • Non-experimental or investigational (Exception: Routine costs for qualifying clinical trial services with performance data on or after September 19, 2000 that meet NCD clinical trial requirements are considered reasonable and necessary).
  • Adequate, including the duration and frequency deemed reasonable for the service in relation to whether it is:
    • Equipped in accordance with accepted standards of medical practice for the diagnosis or treatment of the patient's condition or for improving the function of a malformed body part.
    • Installed in an environment suited to the patient's medical needs and condition.
    • Ordered and assembled by qualified personnel.
    • One that meets but does not exceed the patient's medical needs.
    • At least as advantageous as an existing and available clinically sensible alternative.

REFUND FOR SLEEP STUDY TESTS


Allowance for sleep testing procedures as outlined by the CPT is 100% MAP for providers certified in sleep medicine. All other qualified providers receive 60 percent of the MAP.



Allowance for sleep testing procedures performed in independent sleep laboratories or centers is 100% MAP for facilities accredited by the American Academy of Sleep Medicine (AASM) and/or the Accreditation Commission for Health Care, Inc.

Indications of coverage, limitations and/or medical necessity
Abstract

About 40 million people in the United States suffer from sleep problems each year. Getting little sleep over a long period of time can lead to health problems. Many sleep disorders can be treated by general practitioners; However, when abnormal sleep patterns are not easily explained and further evaluation is required, expert opinion and sleep studies may be required.

Sleep consists of two distinct states: rapid eye movement (REM) and non-rapid eye movement (NREM). REM sleep is when we dream. NREM sleep is divided into three phases. Stages one and two are referred to as light sleep and stage three as deep sleep. The first few sleep cycles of each night contain relatively short periods of REM and long periods of deep sleep. As the night progresses, REM sleep phases increase while deep sleep decreases. In the morning, people spend almost all of their sleep in stages one, two and REM.

Polysomnography (PSG) refers to the continuous and simultaneous monitoring and recording of various physiological and pathophysiological parameters of sleep provided in a sleep laboratory facility that includes medical review, interpretation and reporting. A technician monitors the recording during bedtime and can intervene if necessary. Studies are conducted to diagnose a variety of sleep disorders and to assess a patient's response to therapies such as CPAP (continuous positive airway pressure). PSG differs from sleep studies by including the stage of sleep that is needed
Electroencephalogram (EEG), electroculogram (EOG) and electromyography (EMG).

Parameters 1-3 are required for a simple PSG. Additional parameters that can be monitored include, but are not limited to, the following:

1. At least a 3-channel electroencephalogram (EEG) to measure global neural encephalographic activity with electrodes placed on the scalp

2. Electrooculogram (EOG) to measure eye movements with electrodes placed near the outer corner of each eye

3. A submental electromyogram (EMG) to measure submental electromyographic activity using electrodes placed over the mentalis, submental muscle, and/or masseter regions

4. Rhythm Electrocardiogram (ECG)

5. Nasal and oral airflow via thermistor and nasal pressure sensor for PSG sleep stages with 4 or more additional sleep parameters (95810)

6. Mask airflow with positive airway pressure for PSG sleep stages with 4 or more additional sleep parameters, with initiation of continuous positive airway pressure therapy or bilevel ventilation (95811)

7. Chest wall respiratory effort and abdominal motion measured by respiratory inductive plethysmography, endoesophageal pressure, or by intercostal EMG or validated polyvinylidene fluoride (PVDF) impedance belt.

8. Oxygen saturation (SpO2) by oximetry or transcutaneous monitoring

9. Bilateral tibialis anterior muscle activity, motor activity - movement via EMG

10. Body positions by directly connected sensors or by direct observation

11. Sound recordings to measure snoring

12. Continuous video surveillance

Optional parameters that can be monitored in a sleep study include:

• Temperatura corporal central
• Incident light intensity
• Swelling of the penis
• Pressure and pH at different levels of the esophagus

PSG and other sleep test monitors are generally classified based on the number of biological sensors used and the physiological parameters recorded.

· PSG Type I is covered when used to aid in the diagnosis of Obstructive Sleep Apnea (OSA) in beneficiaries who exhibit clinical signs and symptoms indicative of OSA when performed in a sleep laboratory. Type I devices are capable of recording all physiological parameters and signals defined for PSG. The recording takes place in a sleep laboratory where a technician is physically present to monitor the recording during sleep and intervene if necessary. Minimum requirements include EEG recording, EOG, chin EMG, tibialis anterior EMG, ECG, airflow, respiratory effort and oxygen saturation. Posture must be objectively documented or measured. Trained personnel must always be present and able to intervene.

A Type II sleep testing device is covered when used to aid in the diagnosis of OSA in recipients who exhibit clinical signs and symptoms indicative of OSA when performed unsupervised inside or outside of a sleep laboratory or in a sleep laboratory. Type II devices are wearable devices that can measure the same channels as Type I tests, except that a heart rate monitor can replace the ECG. This device has at least 7 channels (eg EEG, EOG, EMG, ECG heart rate, airflow, respiratory effort and oxygen saturation - this type of device monitors sleep graduation). A sleep coach may not be present at all times in Type II studies, but it is necessary to prepare.

A Type III sleep testing device is covered when used to aid in the diagnosis of OSA in beneficiaries who exhibit clinical signs and symptoms indicative of OSA when performed unsupervised inside or outside of a sleep laboratory facility or at a sleep laboratory facility. sleep. Type III devices monitor and record at least 4 channels and must record ventilation or airflow, heart rate or ECG, and oxygen saturation. A sleep coach may not be present all the time in Type III studies, but it is necessary to prepare.

A Type IV sleep testing device that measures three or more channels, one of which is airflow, is covered when used to aid in the diagnosis of OSA in recipients who exhibit signs and symptoms indicative of OSA when performed unsupervised indoors or out. outside a sleep lab or visited in a sleep lab. Type IV units must include airflow as one of the 3 required channels. Other measurements may include oximetry and heart rate. A sleep coach may not be present at all times in Type IV studies, but it is necessary to prepare.

A sleep testing device that measures three or more channels, including actigraphy, oximetry, and peripheral arterial tone, is covered when used to aid in the diagnosis of OSA in recipients who exhibit signs and symptoms indicative of OSA when left unattended and conducted indoors. either outside a sleep laboratory or seen in a sleep laboratory. A sleep coach may not be present all the time during these studies, but it is necessary to prepare for this.

Multiple sleep latency tests (MSLT) involve four or five 20-minute naps offered at 2-hour intervals. The MSLT objectively assesses sleep tendency by measuring the number of minutes it takes the patient to fall asleep. On the other hand, the keep alert test (MWT) requires the patient to try to stay awake. The MSLT is the superior test for detecting periods of REM during sleep onset, an important determination in diagnosing narcolepsy. To ensure validity, a correct interpretation of the MSLT can only be done after a polysomnogram performed the night before.

Typically, sleep and PSG studies in sleep disorders are performed in sleep centers or laboratories. However, the diagnosis of OSA for CPAP coverage can also be made by home sleep test (HST) as noted in number 2 (sleep apnea) below.

Sleep disorders clinics (centers and laboratories) are facilities where specific disorders are diagnosed through sleep testing. Such clinics (centers and laboratories) are used for diagnosis, therapy and research. Sleep disorders clinics (centers and laboratories) may offer some Medicare-covered diagnostic or therapeutic services. These clinics (centres and laboratories) can be linked to a hospital or independent facilities. Regardless of whether a clinic (sleep center or laboratory) is hospital-affiliated or autonomous, reimbursement for diagnostic services may be subject to different legal requirements than reimbursement for therapeutic services.

Diagnostic tests are covered only if the patient has symptoms or signs of any of the conditions listed below. Most patients undergoing diagnostic testing are not considered inpatients, although they may come to the testing facility in the evening and leave as soon as the testing is complete. If HST is used, they can be tested at home after the sensors have been installed and training on a monitoring device has been received from the sleep center or technical, professional or suitably trained laboratory personnel. The overnight sleep center or laboratory accommodation is considered an integral part of the PSG, MSLT and MWT, but not the HST.

When sleep studies are performed in sleep disorders centers or laboratories, or when HST is used, the following criteria must be met:

· The clinic (sleep center or laboratory) is attached to a hospital or is under medical management and supervision. Diagnostic tests that are routinely performed in sleep disorders clinics (centers and laboratories) may also be covered without direct supervision by a physician;

Patients are referred to the sleep disorders clinic by their treating physicians, and the clinic (center or laboratory) maintains a record of the treating physician's referrals; AND

· The need for diagnostic tests is supported by medical evidence, e.g. B. Confirmed medical tests and laboratory tests. Prior to any sleep test, the patient must undergo a personal clinical examination by the attending physician, which must include at least the following:

1. Sleep history and symptoms, including but not limited to snoring, daytime sleepiness, observed apnea, gagging or wheezing during sleep, morning headache; AND,

2. Epworth Fatigue Scale; AND,

3. Physical examination documenting body mass index, neck circumference, and a cardiopulmonary and upper airway assessment.

accreditation

In order to carry out the technical component (TC) of the PSG and the sleep tests (including HST), the following must be complied with:

The sleep center or laboratory must maintain records showing that it is accredited by the American Academy of Sleep Medicine (AASM), Accreditation Commission for Health Care (ACHC), or is accredited by the Joint Commission as a sleep laboratory. If the GK survey for general hospital accreditation includes the hospital's own sleep laboratory, no additional accreditation is required. This documentation shall be available upon request. AASM, ACHC, or Joint Commission accreditation applies to hospital and independent facilities (including sleep clinics that are part of a physician's office and any other non-hospital facility where sleep studies are conducted. The testing facility (IDTF) must follow supervision and certification guidelines established in the Independent Diagnostic Facility (LCD).

necessary documents

Documentation proving medical necessity must be legible, maintained in the patient's record, and made available to Medicare upon request.

If Medicare is billed for the service, the medical records maintained by the provider must clearly and unambiguously demonstrate the medical need for the sleep study. Medical records must document the name of the physician or technician who participated in the sleep study.

Medicare would not expect an Assessment and Management (E/M) service to be performed on the same day as a sleep study unless significant, separately identifiable medical services are performed and clearly documented in the patient's medical record. Use the 25 modifier appended to the appropriate visit code to indicate that the patient's condition required a significant and separately identifiable service visit unrelated to the procedure performed.

It must be documented that the polysomnography (95808, 95810, and 95811) was performed in an on-site sleep study laboratory and not at home or in a mobile facility.

The sleep disorders clinic should have documentation in the patient's record that the symptoms of narcolepsy are severe enough to affect the patient's well-being and health.

Documentation must show that the home sleep test (G0398, G0399, and G0400) was performed in conjunction with a comprehensive sleep assessment and in patients with a high pretest probability of moderate to severe obstructive sleep apnoea.

Documentation must show that the home sleep test was performed using a Medicare-approved device (eg, describe channels monitored or clearly reference them in the test report).

Documentation demonstrating that the home sleep test (G0398, G0399 and G0400) was administered by a physician who has theIndications and Limitations of Coverage and/or Medical Necessity” above must be made available to Medicare upon request.

Monitored and documented parameters:

  • Start time and length of study day/night.
  • Total sleep time, sleep efficiency, number/duration of awakenings.
  • For sleep stage tests: time and percentage of time spent in each stage;
  • For sleep latency monitoring or maintenance of wakefulness testing: non-rapid eye movement (NREM) and rapid eye movement (REM) sleep latency.
  • Sleep latencies from individual subtests, mean sleep latency, and the number of REM occurrences on the Multiple Sleep Latency Test (MSLT).
  • Breathing patterns, including type (central/obstructive/periodic), number and duration, effect on oxygenation, sleep stage/body position relationship, and response to any diagnostic/therapeutic maneuvers.
  • Heart rate/rhythm and any effect of sleep-disordered breathing on the ECG.
  • Detailed behavioral observations.
  • EEG or EMG abnormalities.

The sleep clinic must be affiliated with a hospital or under the direction and control of a physician (MD/DO), although diagnostic testing may be performed without direct medical supervision.

This information must be documented and made available upon request.

It is recommended that the clinician's director have a reasonable understanding of sleep disorders, as demonstrated by completion of a lung bag or sleep bag, and be a qualified diplomat or adviser to the ABSM.

The patient is referred to the clinic by the attending physician. The physician's order must be kept in the medical record.

Upon request, the sleep disorders clinic must provide Medicare with sufficient documentation that the narcolepsy is severe enough to affect the patient's well-being and health prior to providing Medicare diagnostic test benefits.

If more than two nights of testing are performed, the patient's record must contain documentation that justifies the medical need for the additional test(s).

Acceptable Use Policy

Services performed too frequently are not medically necessary. Frequency is considered exaggerated if services are provided more frequently than is generally assumed by professional colleagues and the reason for additional services is not supported by documentation.

Generally, a maximum of three "naps" is enough to diagnose narcolepsy.

In general, one night is enough to document sleep apnea.

Medicare believes that it is unlikely that it is appropriate or necessary for a patient to take more than one home sleep test per year.

Indications not covered nationally


As of April 4, 2005, the Centers for Medicare and Medicaid Services has determined that, after reviewing current policy, there is insufficient evidence to conclude that multichannel unsupervised portable sleep study tests are appropriate for the diagnosis of OSA for CPAP therapy are appropriate and necessary, and these tests remain uncovered for that purpose.”


“Polysomnography differs from sleep studies by the inclusion of the sleep stage, which is defined to include a 1- to 4-channel electroencephalogram (EEG), an electrooculogram (EOG), and a submental electromyogram (EMG). Other sleep parameters are:


1. ECG (Electrocardiogram)
2. Air flow
3. Ventilation and respiratory effort
4. Gas exchange by oximetry, transcutaneous monitoring or expired gas analysis
5. Muscle activity of the extremities, motor activity-movement
6. Advanced EEG monitoring
7. Swelling of the penis
8. Gastroesophageal reflux
9. Continuous blood pressure monitoring
10. Snoring
11. Body positions, etc.


For a study to be reported as a polysomnogram, sleep must be recorded and staged.” (CPT 2005)


The Multiple Sleep Latency Test (MSLT) is a standardized and well-validated measure of physiological sleepiness. The same parameters of simple polysomnography (PSG) are monitored (usually two eye movements and two EEG channels [central and occipital], in addition to ECG, respiratory flow and submental EMG). The MSLT consists of 4-5 20-minute naps offered at two-hour intervals. The MSLT was designed to quantify sleepiness, determine the need for treatment, and determine premature onset of rapid eye movement (REM) sleep. Studies in normal subjects have shown that latency to falling asleep during these naps correlates with sleep duration on one or more nights prior to the study, maturation, age, sleep continuity, time of day, and medication intake. Pathological areas of sleep latency have been carefully defined. To ensure validity, the correct interpretation of the MSLT can only be done after a PSG performed the night before. For each nap, the latency between "lights out" and falling asleep is determined. An average latency of 5 minutes or less indicates severe excessive sleepiness. The number of naps during which REM sleep occurs is also noted. Repeat MSLT testing is only necessary if 1) the initial test is deemed to be an invalid representation of the patient's condition; 2) the initial test is inconclusive; 3) response to treatment must be evaluated; or 4) suspected more than one sleep disorder.


Polysomnography and/or multiple sleep latency studies will only be performed and covered if the patient has symptoms or signs that suggest the diagnosis of any of the following conditions, with the exception of impotence:


A. Narcolepsy


This term refers to a syndrome characterized by abnormal sleep tendencies, e.g. B. Excessive daytime sleepiness or disturbed nighttime sleep. Associated diagnostic tests are covered if the patient has episodes or bouts of inappropriate sleep, such as while driving, during a meal, or in the middle of a conversation. Other examples are episodes of amnesia or persistent drowsiness. Typically, at least three naps are needed to diagnose narcolepsy. The diagnosis can be confirmed by polysomnography or multiple sleep latency test. If more than three naps are reported, there must be compelling medical evidence to justify the need for additional testing.


B. Sleep apnea


This is a potentially fatal condition where the patient stops breathing while sleeping. Three types of sleep apnea have been described (central, obstructive and mixed). The nature of apneic episodes can be documented by appropriate diagnostic tests. Sleep apnea can be diagnosed by a single polysomnogram, including EEG recordings, for at least 6 hours. The 2005 CPT describes sleep testing as follows: “Sleep studies and polysomnography refer to continuous, simultaneous monitoring and recording of various physiological and pathophysiological sleep parameters for 6 or more hours with physician review, interpretation, and report. Studies are being conducted to diagnose a variety of sleep disorders and to assess patient response to therapies such as nasal continuous positive airway pressure (NCPAP).


C. Impotence


Polysomnography and sleep studies in impotence are not covered in this guideline.


D. Parassonia


Parasomnias are a group of conditions that represent unwanted or unpleasant events during sleep. Behavior during these periods can cause damage to the area and injury to the patient or others. Parasomnia can include conditions such as sleepwalking, night terrors, and rapid eye movement (REM) sleep patterns. In many of these cases, the nature of these conditions can be determined by careful clinical examination. The suspicion of seizure disorders as a possible cause of parasomnia is adequately evaluated by EEG (electroencephalogram) studies of standard or prolonged sleep. In cases where seizure disorders have been ruled out and in cases where there is a history of repeated violent or painful episodes during sleep, polysomnography may be useful in providing a diagnostic or prognostic classification.


E. Polysomnography at chronic insomnia is not covered.


At present, there is no convincing evidence that polysomnography in a sleep disorders clinic provides definitive diagnostic data for chronic insomnia; or that such information is useful in patient care; or is associated with an improved clinical outcome. The use of polysomnography to diagnose patients with chronic insomnia is not covered by Medicare because it is not appropriate and required under Section 1862(a)(1)(A) of the Act.


F. Therapeutic Benefit Coverage:


Sleep disorders clinics can sometimes provide therapeutic and diagnostic services. Therapeutic services may be provided in an outpatient setting in a hospital or in a self-contained facility, provided they meet the relevant requirements of the respective type of service, are reasonable and necessary for the patient, and are provided under direct medical supervision. supervision.


Most patients undergoing diagnostic testing are not considered inpatients, although they may come to the testing facility in the evening and leave after testing is complete.


Overnight accommodation is considered an integral part of these exams. Polysomnography includes sleep staging, which is defined to include a 12-4 channel electroencephalogram (EEG), an electrooculogram (EOG), and a submental electromyogram (EMG). Additional sleep parameters include electrocardiogram (ECG); air flow; ventilation and respiratory effort; gas exchange by oximetry, transcutaneous monitoring, or analysis of expired gas; muscle activity and/or motor activity of the extremities; extended EEG monitoring; continuous monitoring of blood pressure; Snoring; and body positions, etc. For a study to be reported as a polysomnogram, sleep must be recorded and staged. Sleep studies should be conducted in a sleep laboratory supervised by a physician trained in the analysis and interpretation of records. The study must be performed in a hospital, independent diagnostic testing center, or sleep laboratory, supervised by a trained technician, and must be an observed study.


Polysomnography may be indicated for snoring when nocturnal oximetry shows desaturation below 90% more than 5% of the time. A combined diagnostic/therapeutic study (CPAP) may be indicated.


Snoring and nasal obstructive signs and symptoms are not in themselves indications for polysomnography, but may be indicative of sleep apnea when other findings are present. Other causes of sleepiness should be ruled out using a sleepiness scale before performing a sleep study.

Billing Guidelines for UHA Insurance

Polysomnography (sleep studies)

The University Health Alliance (UHA) will reimburse polysomnography (sleep studies) if deemed medically necessary and if it meets the medical criteria guidelines below (subject to limitations and exclusions).

A. Polysomnography/Sleep Studies are covered (subject to limitations/exclusions and administrative policies) when the following criteria are met:

1. The patient was clinically examined in person by the attending physician prior to the study to determine sleep-disordered breathing. The assessment must include at least the following:

a) Signs and symptoms of breathing disorders during sleep
b) Duration of symptoms
c) Concomitant illnesses (e.g. high blood pressure, heart disease, stroke)
2. The patient (of any age) has two of the following indications:
a) Habitual snoring that bothers you
b) The patient has unexplained pathological daytime sleepiness and/or unrefreshing sleep.
c) A family member or bed partner has noticed that the patient stops breathing, gasping, or vomiting during sleep
d) Obesity with a BMI of 30 or more
e) At least two of the following statements are true:
me) stroke
i) heart failure
iii) Unexplained cor pulmonale
iv) Unexplained polycythemia
v) Essential Hypertonia
vi) Untreated hypothyroidism
vii) craniofacial anomalies (eg Down syndrome, acromegaly)
viii) Narcolepsy
ix) Sono-related myoclonus

3. For children (under 18 years old) who do not meet the above criteria, one of the following indications is filled in in addition to criterion II.A.2.a, b, c or d:
a) Attention Deficit Hyperactivity Disorder
b) nocturnal enuresis
c) hypertrophy of tonsils and/or adenoids

d) Safety concerns due to dangerous behavior during parasomnia, excessive sleep disturbance of family members or when considering pharmacotherapy.

e) Concern about nocturnal seizures. In this case, the PSG should contain an electroencephalogram with 16 to 18 leads.

4. Polysomnography/sleep study is performed in a hospital sleep laboratory or independent sleep laboratory that meets the following requirements:

a) Hospital sleep laboratories fall within the scope of Joint Commission accreditation for their facilities;

i) The autonomous sleep laboratory is complete and currently accredited by the American Association of Sleep Medicine (AASM) (http://www.aasmnet.org).

5. The polysomnogram/sleep study will be evaluated by a sleep physician certified by the American Board of Sleep Medicine (ABSM) or the American Board of Medical Specialties (ABMS).

B. The polysomnography/sleep study must be performed with the intention of completing the study with positive airway pressure (PAP) titration, ie H. Code CPT 95811. Code CPT 95810 is only permitted if the study of the sleep did not show events consistent with sleep apnea or sleep apnea. PAP titration cannot be completed due to unforeseen reasons as documented in the polysomnography report. Examples include, but are not limited to, the following:

1. Total time I am insufficient;

2. Criteria for obstructive sleep apnea were met at the end of the study, with insufficient sleep time remaining for continuous positive airway pressure (CPAP) titration;

3. Attempted CPAP but not tolerated by the patient.

C. A polysomnogram/sleep study will be performed every five years unless there is a significant change in the patient's condition. A repeat polysomnography five years ago is adopted for the following indications:

1. Weight gain or loss of ten percent of body weight;

2. After surgical or oral device treatment of patients with moderate to severe OSA;

3. When clinical response is insufficient or when symptoms recur despite an initial good response to PAP treatment.

4. Follow-up PAP titration study if indicated and failure to complete the split overnight sleep study as in II.B.

D. Various sleep latency tests (CPT code 95805) are adopted for the evaluation of patients with suspected narcolepsy to confirm the diagnosis.

E.NOTE:

This UHA Payments Policy is a guide to coverage, pre-approval requirements and other administrative policies. It is not intended to provide guidance for the practice of medicine and should not preclude the practitioner from expressing judgment.

While this Payments Policy may indicate that a particular service or delivery is considered covered, certain Provider contractual terms and/or individual Member benefit plans may apply and this Policy is not a guarantee of payment. UHA reserves the right to apply this payment policy to all UHA companies and affiliates.

The UHA understands that opinions and approaches to clinical problems may differ. Matters of medical necessity (see Revised Hawaii Statutes §432E-1.4) are welcome. A provider may request that UHA review the application of medical necessity criteria in light of any supporting documentation.

A. A two-night study (CPT 95811) in which obstructive sleep apnea (OSA) is documented during the first half of the study, followed by CPAP titration during the second half of the study, eliminates the need for a second polysomnogram to CPAP titration. A split-night study would be appropriate for patients with a baseline apnea index or AHI of at least 15 events per hour, or 5 to 14 events per hour with documented symptoms of excessive daytime sleepiness, impaired cognition, mood disturbances, or insomnia; or a history of hypertension, ischemic heart disease, or stroke. As CPT code 95811 involves initiation of CPAP therapy, CPT code 94660 is not payable separately.

B. Unsupervised home sleep studies are not appropriate and will not be covered for the evaluation of obstructive sleep apnea. Polysomnography is required to assess OSA; therefore, unsupervised home sleep studies are not covered. Supervised studies are important to ensure monitors are properly attached to the patient and do not come loose overnight. In addition, a supervisor can identify sleeping positions that aggravate OSA and snoring patterns and detect severe apnea, allowing CPAP to be started immediately.

C. The Epworth Sleepiness Scale is considered clinically appropriate as part of the OSA assessment, but is performed as part of patient assessment and management and is not paid for separately.

D. UHA's global payment for polysomnography includes payment for EEG, EOG, and EMG. These services are not paid separately.

E. Other measurements taken during a sleep study (eg, vital signs, muscle activity, oximetry, airflow, blood gases, penile engorgement, gastroesophageal reflux) are also an integral part of the Service and will not be paid for separately.

F. CPT code 95810 is covered only as mentioned above (II.B.).

G. Polysomnography/Sleep Studies are only covered once every five years, except as noted above (II.C).

95811 Sleep staging with 4 or more additional sleep parameters, with initiation of continuous positive airway pressure therapy or bilevel ventilation, accompanied by a technician

Other information

According to the American Academy of Sleep Medicine (AASM) (Epstein et al., 2009), the diagnosis of OSA is confirmed when the number of obstructive events* (apneas, hypopneas + awakenings related to respiratory events) in the PSG is higher at 15 events/hour with no associated symptoms or greater than 5/hour in a patient reporting any of the following: unintentional sleep episodes while awake; daytime fatigue; non-restorative sleep; Fatigue; Insomnia; waking up panting, gasping, or choking; or the bed partner describes loud snoring, pauses in breathing, or both during the patient's sleep.

The frequency of obstructive events is given as AHI or RDI. The RDI was sometimes used interchangeably with the AHI, but at other times included total apnoeas, hypopnoeas, and respiratory effort-related arousals (RERAs) per hour of sleep. When using a wearable monitor that does not measure sleep, the RDI refers to the number of apneas plus hypopneas per hour of recording.

The severity of OSA is defined as:

* Leve para IAH ou RDI = 5 e < 15

* Moderate for AHI or RDI = 15 and = 30

* Record for AHI or RDI > 30/h The AASM classifies sleep study devices (sometimes referred to as a type or level) as follows (Collop et al., 2007):

* Type 1: Fully supervised PSG (= 7 channels) in laboratory environment

* Type 2: Fully unattended PSG (= 7 channels)

* Type 3: Limited channel devices (typically 4-7 channels)

* Type 4: 1 or 2 channels, usually using oximetry as one of the parameters

In a randomized, single-blind crossover study, Bakker et al. (2011) compared the effectiveness of CPAP and APAP (S8 Autoset II®, ResMed) over a period of six nights at home, separated by a four-day washout, in 12 morbidly obese OSA patients requiring high therapeutic pressure (AHI 75, 8+) required 32.7, body mass index 49.9+5.2 kg m-2, mean pressure 16.4 cmH2O) with no significant comorbidity. Both therapies significantly reduced the AHI (APAP 9.8+9.5 and CPAP 7.3+6.6 events h-1

; P = 0.35), but residual measures of PSG disease (AHI > 5) were common. APAP provided significantly lower pressure at the 95th percentile on average in the home arm than CPAP (14.2 + 2.7 and 16.1 + 1.8 cmH2O, respectively, P = 0.02). The authors concluded that this study supports the use of manually titrated APAP or CPAP in this specific population. As APAP-assessed AHI significantly overestimated the level of residual disease compared with laboratory-assessed AHI, the authors recommend objective assessment by a sleep study when APAP indicates a high level of residual disease.

Pap tests

In a pilot study, Krakow et al. (2008) evaluated the impact of the PAP-Nap sleep study on adherence to PAP therapy in insomniac patients with sleep disorders (SDB). Combining psychological and physiological treatments in one procedure, PAP nap testing includes mask and pressure desensitization, emotion-focused therapy to overcome aversive emotional responses, mental imagery to divert the patient's attention from mask or pressure sensations, and physiological exposure to therapy PAP during a 100 minute nap. Patients treated with the PAPNap test (n=39) were compared to a historical control group (n=60) of insomniac patients with SDB who did not receive the test. All 99 insomniac patients were diagnosed with SDB (mean AHI 26.5 +/- 26.3, mean RDI 49.0 +/- 24.9) and all reported a history of psychiatric disorders or symptoms and resistance to PAP therapy. Of the 39 patients who completed the PAP-Nap, 90% completed overnight titrations compared to 63% in the historical control group. 85% of the sleep test group filled PAP therapy prescriptions at home, compared to 35% of the control group. Sixty-seven percent of the sleep test group used PAP therapy regularly, compared to 23 percent of the control group. Using standards from the field of sleep medicine, the sleep test group showed objective adherence of 49% to 56% compared to 12% to 17% for controls. More results from large prospective studies are needed to assess the clinical value of this test.

Treatment of OSA: Positive airway pressure (PAP), resulting in pneumatic immobilization of the airway, is the mainstay of OSA treatment. The pressure delivered during the breathing cycle can be constant (CPAP) or vary between inspiration and expiration (bi-level CPAP or BPAP). Automatic positive airway pressure (APAP) titration provides a variable pressure in response to changes in various parameters, e.g. B. sleeping position, sleep stage, or changes in body habits. Although some patients preferred APAP or BPAP over CPAP, the use of APAP or BPAP did not increase adherence.

For patients requiring CPAP or BPAP treatment, pressure levels should be adjusted to each patient's specific needs. For patients whose diagnostic sleep study is performed in the laboratory, it may be possible to diagnose OSA and conduct the titration study in a single night. This approach, known as a split night study, can be used when the AHI exceeds 20 per hour based on the first 2 hours of the test. Those who do not meet the criteria for the two-night protocol will require a second nighttime titration study or temporary use of APAP as the CPAP titration medium. Titration is not necessary when APAP is chosen as a long-term therapeutic approach. Oral appliances (OA), including mandibular reduction appliances (MRA) and tongue retractors (TRD), can be used in appropriately selected patients. Other treatments for OSA (not covered in this guideline) include positional therapy, non-surgical weight loss measures, or bariatric surgery. Surgical approaches to modifying the upper airway are generally reserved for patients who have failed or are intolerant of other therapies. Tracheostomy should be considered when other measures fail and the OSA is considered severe enough to warrant this procedure. Adenotonsillectomy is the preferred first approach for treating OSA in children. CPAP is reserved for children who have had an inadequate response to surgery, do not have enlarged tonsils, or are not good candidates for surgery.

When treating patients with OSA, long-term adherence with positive airway pressure devices remains problematic. Adherence is defined by the Centers for Medicare and Medicaid Services (CMS) as using PAP for more than or equal to 4 hours per night on 70% of nights for a period of thirty (30) consecutive days. Adherence can be as low as 50% after one year, and for this reason, monitoring adherence is an important part of managing patients with OSA. Every effort must be made to achieve compliance. Newer PAP devices record usage times (and can broadcast them) so compliance monitoring can be done remotely. Unless compliance is achieved and documented, continued use of PAP equipment (and continued supply of related supplies) cannot be considered medically necessary.

Established OSA - home sleep follow-up studies:

A patient with a confirmed diagnosis of OSA should have a home sleep assessment if any of the following apply AND there is no contraindication for a home sleep assessment, as listed in Table 1 below:

1. To evaluate the effectiveness of surgery (including adenotonsillectomy or upper airway) or oral appliances/devices; OR

2. Reassess the diagnosis of OSA and the need for continued CPAP therapy if there is significant weight loss (defined as 10% of body weight) since the last sleep study

Table 1: Contraindications for home sleep study

1. The patient is 18 years old or younger

2. Moderate or severe chronic obstructive pulmonary disease (COPD) - Forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) less than or equal to 0.7 and FEV1 less than 80% of predicted

3. Moderate or severe congestive heart failure (CHF) - New York Heart Association (NYHA) Class III or IV

4. CHF with a history of ventricular fibrillation or sustained ventricular tachycardia in a patient without an implanted defibrillator

5. Cognitive impairment (inability to follow simple instructions) resulting in inability to use the home sleep tester when no other person is available to help with the task

6. Physical disability that results in the inability to use the home sleep tester if no other person is available to help with the task

7. The patient has a suspected or established diagnosis of any of the following disorders: (a) central sleep apnea, (b) periodic limb movement disorder (PLMD), (c) narcolepsy, (d) idiopathic hypersomnia, ( e) parasomnia (except bruxism and sleep talk [Sleep Talk]), (f) Nocturnal Seizures – To support the suspicion of PMS in this context, one of the following (i-vi) must be documented: (i) pregnancy, (ii) insufficiency renal impairment, (iii) iron deficiency anemia, (iv) peripheral neuropathy, (v) use of antidepressant or antipsychotic medications, or (vi) persistent hypersomnia and clinical symptoms of PMS following sleep disturbances, which are ruled out by sleep testing home.

8. Previous technically suboptimal home study sleep (attempted 2 nights of study if reason for suboptimal study is likely to recur on second attempt or if study remains suboptimal after 2 nights attempted)

9. Preliminary 2-night home sleep study without an OSA diagnosis in a patient with ongoing clinical suspicion of OSA.

10. The patient is oxygen dependent for some reason

11. History of cerebrovascular accident (CVA) in the last 30 days

12. Chronic use of opiates when abstinence is not possible. Diagnostic sleep testing for patients taking opioid narcotics for acute self-limiting conditions should ideally be deferred until medications are discontinued.

13. Body mass index (BMI) >33 and elevated serum bicarbonate (>28 mmol/L)

14. Established diagnosis of obesity hypoventilation syndrome, defined as body mass index (BMI) > 30 kg/m2 and hypoventilation not solely attributable to other conditions such as lung disease, skeletal restriction, neuromuscular weakness, hypothyroidism, pleural pathology or medications . Documentation of hypoventilation requires an increase in arterial PCO2 (or a surrogate measure) to >55 mmHg for at least 10 minutes or an increase in arterial PCO2 by >10 mmHg

(or proxy) during sleep (compared to a supine waking value) to a value of at least 50 mmHg for at least 10 minutes.
