Coverage Summary

This UnitedHealthcare policy (New Mexico only) defines medical necessity criteria for sleep studies including Home Sleep Apnea Testing (HSAT), attended full‑channel polysomnography (PSG, attended laboratory studies), daytime studies (MSLT, MWT), attended PAP titration (split‑night or full‑night), and repeat testing, and lists exclusions (e.g., actigraphy and select PSG indications). The geographic scope is explicitly New Mexico only. The policy applies adult HSAT indications and distinguishes children/adolescents (<18 years) as a group for whom attended PSG is indicated. Overall coverage stance is mixed: HSAT is medically necessary for appropriately selected adults, attended PSG and other studies are medically necessary under specified clinical circumstances, and several tests/studies are listed as not medically necessary.

Background & Evidence

Background: Obstructive Sleep Apnea (OSA) and other sleep disorders may be evaluated either at home or in a sleep laboratory. HSAT (unattended) uses portable monitors to record respiratory parameters (breathing/airflow, heart rate, oxygen saturation) and is intended to assess OSA without determination of sleep stage; an adequate HSAT records a minimum of 4 hours and includes sensors such as nasal pressure, chest and abdominal effort, and oximetry. In contrast, attended polysomnography (PSG) is a laboratory‑based, technologist‑attended, full‑channel study (Type 1) that records multiple physiologic signals including EEG, EOG, EMG, respiratory effort, airflow, oximetry, movement and cardiac activity.

Device classification and diagnostic criteria: The AASM classifies devices as Type 1 (full attended PSG, ≥7 channels), Type 2 (full unattended PSG, ≥7 channels), Type 3 (limited channel devices, typically 4–7 channels), and Type 4 (1–2 channels, often oximetry). The AASM diagnostic thresholds define OSA severity by AHI or RDI as mild ≥5 and <15 events/hour, moderate ≥15 and ≤30 events/hour, and severe >30 events/hour. AASM guidance supports using HSAT with a technically adequate device in uncomplicated adults at increased risk of moderate-to-severe OSA, and recommends that if a single HSAT is negative, inconclusive, or technically inadequate, PSG should be performed rather than repeating HSAT.

Citation	Key Point
Kapur et al., 2017
If a single HSAT is negative, inconclusive, or technically inadequate, PSG is strongly recommended rather than repeating HSAT; adequate HSAT defined as minimum 4 hours with nasal pressure, chest and abdominal effort, and oximetry.
AASM diagnostic thresholds
OSA severity defined by AHI/RDI: Mild ≥5 and <15; Moderate ≥15 and ≤30; Severe >30 events/hour; diagnostic thresholds described for when PSG/HSAT confirm OSA.
PAP-Nap pilot results (Krakow et al., 2008)
Pilot PAP-Nap: higher completion of overnight titrations (90% vs 63%), higher prescription fills (85% vs 35%), and higher regular PAP use (67% vs 23%) versus historical controls; authors call for larger prospective studies.
AASM guidance (Kapur et al., 2017)
AASM recommends that if a single HSAT is negative, inconclusive, or technically inadequate, PSG be performed for diagnosis of OSA (strong recommendation); single-night HSAT generally adequate in appropriate populations but repeat HSAT not recommended after a non-diagnostic result.
AASM actigraphy recommendations (Smith et al., 2018b)
AASM suggests clinicians may use actigraphy for estimating sleep parameters in insomnia and circadian rhythm disorders (conditional) and recommends not using actigraphy in place of EMG for diagnosing periodic limb movement disorder (strong).

Implantable Hypoglossal Nerve Stimulator - Pre-implantation/Calibration Testing

Attended PSG is medically necessary to rule out Central Sleep Apnea prior to implantation and/or calibration when device is indicated.

PSG performed prior to implantation/calibration to rule out Central Sleep Apnea.

Refer to Obstructive and Central Sleep Apnea Treatment policy for device indications.

Studies Not Medically Necessary

The following are not medically necessary due to insufficient evidence:

Attended full-channel PSG for evaluating Circadian Rhythm Disorders.

Attended full-channel PSG for evaluating Depression.

Attended full-channel PSG for evaluating Insomnia.

Actigraphy for any sleep disorders.

Daytime Sleep Studies - MSLT and MWT

Medically necessary criteria for daytime testing:

MSLT is medically necessary for evaluating suspected Narcolepsy or idiopathic Hypersomnia when other causes of Excessive Sleepiness have been excluded by appropriate clinical assessment.

MWT medically necessary criteria (adults only): An adult who is unable to stay awake, resulting in a safety issue.

MWT medically necessary criteria (adults only): Assessing response to treatment in adults with sleep disorders.

MWT is unproven and not medically necessary in children and adolescents less than 18 years of age.

Abbreviated daytime sleep studies (e.g., PAP-Nap) are not medically necessary due to insufficient evidence of efficacy.

Attended PAP Titration - Medically Necessary

When individual meets attended PSG criteria, the following titration studies are medically necessary:

A split-night sleep study performed in a healthcare facility or laboratory setting for diagnosis and PAP titration.

A full night study for PAP titration when a split-night study is inadequate or not feasible and the individual has a confirmed diagnosis of OSA.

Attended Repeat Testing - Medically Necessary

Repeat attended PSG and repeat PAP titration are medically necessary in the following circumstances:

Individuals with persistent, recurrent or new symptoms despite documented appropriate current treatment or PAP therapy (examples: equipment failure, improper mask fit, pressure leaks, unsuccessful titration, inadequate pressure) and medical problems (including nasal congestion) have been addressed and appropriately managed.

Individuals who have experienced a clinically significant weight loss or gain (≥ 10%) or changes in cardiovascular disease since the last study.>= 10% weight change

Repeat Testing for Oral Appliance Adjustments

Operational note:

Repeat testing and repositioning/adjustments for oral sleep appliances can be done in the home unless the individual meets criteria for an attended sleep study.

Home Sleep Apnea Testing (HSAT) — repeat testing recommendation

Policy notation regarding repeat HSAT after an initial non-diagnostic result:

Performing a repeat HSAT is not recommended when an initial HSAT is negative, inconclusive, or technically inadequate, due to the higher likelihood that a second HSAT will also be negative, inconclusive, or technically inadequate

After a single negative, inconclusive, or technically inadequate HSAT result, performance of attended full-channel polysomnography is strongly recommended

Attended Full-Channel Polysomnography (PSG) — suspected OSA

Revised coverage criteria for attended PSG in evaluating suspected OSA:

Attended full-channel PSG is indicated when results of previous HSAT (within the past 12 months) are negative, indeterminate, or technically inadequate to make a diagnosis of OSAHSAT within 12 months

Daytime Sleep Studies — MSLT

Revised MSLT coverage language:

Multiple Sleep Latency Testing (MSLT) is medically necessary for evaluating suspected narcolepsy when other causes of excessive sleepiness have been excluded by appropriate clinical assessment

Attended Repeat Testing (PSG / PAP titration)

Criteria for repeat attended studies and titration:

Repeat attended full-channel polysomnography and repeat Positive Airway Pressure (PAP) titration are medically necessary for individuals who have persistent or new symptoms despite documented appropriate current treatment or PAP therapy

Repeat attended full-channel polysomnography and repeat PAP titration are medically necessary for individuals who have experienced a clinically significant weight loss or gain (≥ 10%) since the last study>= 10% weight change

Repeat attended full-channel polysomnography and repeat PAP titration are medically necessary for individuals who have changes in cardiovascular disease since the last study

Policy applies to New Mexico members

This policy applies to New Mexico members. Verify state-specific regulatory requirements, member eligibility, and benefit plan provisions prior to ordering or performing testing.

Denial Risk

ABP members age 21 and over exclusion

Sleep studies are not covered for Alternative Benefit Package (ABP) members age 21 and over. Confirm ABP status and age before authorizing or performing testing to avoid coverage denials.

Documentation Required

HSAT adequacy and repeat testing guidance

Repeat HSAT is not recommended after a single negative, inconclusive, or technically inadequate HSAT because of the low likelihood that a second test will be diagnostic. When an initial HSAT is non-diagnostic, attended full-channel polysomnography (PSG) is strongly recommended.

Prior Authorization

Perform attended PSG after non-diagnostic HSAT

If an initial HSAT is negative, inconclusive, or technically inadequate, proceed to an attended full-channel PSG rather than repeating HSAT. Consider prior authorization/workflow implications for scheduling attended PSG when HSAT is non-diagnostic.

Prior Authorization

Repeat PSG / PAP titration criteria

Repeat attended PSG and repeat PAP titration should be obtained only for individuals with persistent, recurrent, or new symptoms despite documented appropriate current treatment or PAP therapy, or for individuals who have experienced a clinically significant weight change (≥ 10%) or changes in cardiovascular disease since the prior study.

Persistent, recurrent, or new symptoms despite documented appropriate treatment
Clinically significant weight change (≥ 10%) since prior study
Changes in cardiovascular disease since prior study

Documentation Required

Follow federal/state/contractual requirements

Benefit coverage is determined by federal, state, or contractual requirements and applicable laws. Providers must reference the member's applicable benefit plan for specific coverage rules; this policy is informational and does not replace plan language.

AHI (Apnea Hypopnea Index)Number of apneas plus hypopneas per hour of sleep; used to classify OSA severity

MWT (Maintenance of Wakefulness Test)Daytime test measuring ability to stay awake in nonstimulating conditions; medically necessary in adults for safety or treatment assessment
