Section 3.3 lists these acceptable reasons.
Follow-up Polysomnography
Medicaid shall cover follow-up polysomnography when ONE of the following criteria is met:
Section 3.4 lists these conditions.
Billing and Reimbursement Criteria
Coverage and billing follow these rules:
Section 1.E.1.a.
Section 1.E.1.b–d.
Section 1.E.1.c.
Section 1.E.2.a–f.
The policy's Table of Contents explicitly indicates sections titled "When the Procedure, Product, or Service Is Not Covered" and "Specific Criteria Not Covered", which document exclusions and non-covered categories elsewhere in the policy. These headings notify providers that explicit exclusion rules exist and must be consulted in Section 4.0 and related subsections before billing or requesting prior approval.
Coverage for Home Sleep Tests (HST) is restricted: HSTs are only appropriate for diagnosing obstructive sleep apnea when the beneficiary has a high pretest probability and no significant comorbid conditions or alternative sleep disorders are suspected. The Table of Contents and specific coverage language require that no significant comorbid conditions exist that could impact study accuracy and that other sleep disorders (e.g., central sleep apnea, PLMD, insomnia, parasomnias, circadian rhythm disorders, narcolepsy) are not suspected before using HST instead of in-lab PSG.
The policy specifies services that are not covered: sleep studies and polysomnography are not covered for impotence; chronic insomnia except when an underlying physiologic cause is present; and simple snoring except when associated with underlying physiologic findings (for example disturbed sleep patterns, excessive daytime sleepiness, unexplained awake hypercapnia, apneic breathing, cognitive problems, or excessive fatigue).
When polysomnography (PSG) is billed, certain related procedures cannot be billed separately on the same date of service. The policy clarifies billing structure: PSG and sleep studies may be billed as a complete procedure or as separate professional and technical components, and the complete procedure is considered an episode of care for billing purposes.
The policy lists specific procedures that are not separately reimbursable when billed on the same date of service with PSG, including 24‑hour ECG monitoring (CPT codes 93224–93272), pulse oximetry determinations (94760, 94761), pediatric pneumogram for age six and under (94772), CPAP initiation/management (94660), EEG (95812–95827), and facial nerve studies (92516), when billed with polysomnography (CPT 95800–95811).
The Table of Contents and billing section reiterate that separate reimbursement is not allowed for specified procedures when billed on the same date of service with sleep studies/polysomnography, and that polysomnography/sleep studies are limited to one procedure per date of service whether billed by the same or a different provider.
The Table of Contents includes entries for "Specific Criteria Not Covered" and "Specific Criteria Not Covered by Medicaid", indicating dedicated sections in the policy that enumerate services and clinical scenarios that Medicaid considers non‑covered. Providers should consult Section 4.0 and its subsections for the full list of specific non‑coverage criteria.
For Medicaid beneficiaries, the Table of Contents indicates under eligibility provisions that "Medicaid: None Apply" for additional specific Medicaid criteria — i.e., no separate additional Medicaid‑only coverage criteria are listed beyond the policy's standard criteria.

Provider Requirements, Prior Authorization, and Documentation
Prior approval required for specified sleep studies
Certain polysomnography/unattended sleep study services require prior approval; see the policy’s Prior Approval and Prior Approval Requirements sections for specifics and submit requests to the DHHS Utilization Review Contractor as required.
EPSDT — prior approval still required for beneficiaries <21
If the beneficiary is under age 21, the prior approval requirement still applies under EPSDT — providers must follow EPSDT guidance and NCTracks instructions when requesting exceptions to policy limitations.
- EPSDT does not eliminate prior approval requirements; consult NCTracks Provider Claims and Billing Assistance Guide and the EPSDT provider page for details.
Prior approval and documentation for unattended (HST) studies
Prior approval is required for unattended (unsupervised) sleep studies; the prior approval submission must include medical records documenting that the patient meets the Home Sleep Test criteria listed in Subsection 3.2.1.b.
Use specified CPT/HCPCS codes from Attachment A
Use the CPT codes listed in Attachment A when billing or requesting prior approval for polysomnography and home sleep tests; the attachment lists codes such as 95800, 95805–95808, 95810–95811, and 95782–95783.
Bill as complete procedure or correct professional/technical components
Bill PSG/sleep studies either as the complete procedure or as professional (PC) and technical (TC) components; do not bill the complete procedure and separate components for the same date of service.
- If billing the complete procedure, report the date the procedure began as the date of service.
- If billing components, report the date the specific component was rendered.
Coverage only when specified medical necessity criteria are met
Coverage is criteria-based: the ordered diagnostic criteria in Sections 3.1–3.3 must be met and supported in the medical record for the service to be covered.
When HST can be used instead of in‑lab PSG
Home Sleep Test (HST) may be used when in-laboratory PSG is not possible, or when OSA diagnosis has been established and therapy initiated and response is being evaluated — provided no significant comorbid conditions or other sleep disorders are suspected.
- HST is limited to diagnosis of OSA and to specified device types (Type II/III/IV or PAT).
Documented justification required for repeat PSG
Repeat in-lab polysomnography for diagnosis requires prior justification and documentation of medical necessity and at least one of the listed reasons (technically inadequate first study, insufficient sleep, inconclusive results, or need to initiate/confirm therapy efficacy).
Component billing exclusivity and single-procedure limit
PSG may be billed as complete procedure or as separate professional and technical components, but the technical or professional component cannot be billed on the same date of service as the complete procedure.
- If components are billed separately, use the date the service was rendered as the date of service.
- Only one PSG/sleep study procedure is allowed per date of service by same or different provider.
No step therapy requirements specified
No step therapy requirements are specified in this policy section; there is no mandated trial sequence before authorization documented here.
Claims and code reporting requirements
Attach Attachment A and supporting claims documentation per policy: report ICD-10-CM/PCS to highest specificity and use the most specific CPT/HCPCS code that describes the service.
- Follow current ICD-10 and CPT/HCPCS editions in effect at the time of service.
- Use appropriate unlisted codes only if no specific code exists.
HST documentation and minimum data requirement
For home sleep tests, the interpreting physician must examine all raw data and confirm the test collected a minimum of six hours of data during the beneficiary’s usual sleeping period before interpretation and billing.
- HST devices must be an approved device type (Type II/III/IV or PAT).
- Minimum data collection requirement: at least 6 hours during usual sleep period.
Facility accreditation required for supervised PSG
Supervised (in‑lab) PSG technical components must be performed in a facility accredited by AASM, ACHC, or the Joint Commission; the sleep center must maintain accreditation documentation on file.
- Maintain accreditation records showing AASM, ACHC, or Joint Commission accreditation for the technical component.
Documents to include with prior approval requests
Submit the prior approval request plus all supporting health records that demonstrate the beneficiary meets the specific criteria in Subsection 3.2 (e.g., HST eligibility, device type, pretest probability, raw data review).
- Medical records must document the Subsection 3.2.1.b criteria when requesting prior approval for HST.
Require raw-data review and retain accreditation/test records
Reading physicians must examine all raw HST/PSG data when interpreting studies, and the center must retain accreditation documentation and test records to support the interpretation.
Procedure coding determines billing units
Procedure code(s) reported determine the billing unit(s); report the most specific procedure code(s) to reflect the service provided and establish billing units accordingly.
Criteria-based coverage — document each required criterion
Coverage is determined by whether the specified criteria (Sections 3.1–3.3) are met and documented; ensure medical records explicitly support each criterion used to justify the study.
Denial risk if prior approval or prior testing documentation is missing
If a prior approval request lacks required documentation or previous testing requirements are not met, the request may be denied; include prior approvals and prior test results as specified.
Verify beneficiary eligibility at time of service
Verify Medicaid beneficiary eligibility at the time of service; failure to verify eligibility or billing ineligible beneficiaries may result in denial or nonpayment.
General denial conditions — eligibility, criteria, duplication, investigational services
Requests will be denied when the beneficiary does not meet Section 2.0 eligibility, does not meet Section 3.0 coverage criteria, the service duplicates another provider’s service, or is experimental/investigational or part of a clinical trial.
HST-specific denial triggers and excluded comorbidities
Unattended sleep studies/HST are not covered for beneficiaries under 18, for beneficiaries at low-to-moderate risk of OSA, after a negative/inconclusive/technically inadequate HST, or for patients with specified comorbidities listed in Section 4.2.1.c.
- Comorbidities excluding HST include moderate–severe pulmonary disease, neuromuscular respiratory disease, congestive heart failure, suspicion of other sleep disorders, other respiratory disorders, history of stroke, and chronic opioid use.
Procedures not separately reimbursable with PSG on same date
The following procedures are not separately reimbursable on the same date of service as PSG (CPT 95800–95811): ECG monitoring (CPT 93224–93272), pulse oximetry (94760–94761), pediatric pneumogram (94772, age ≤6), CPAP initiation/management (94660), EEG (95812–95827), and facial nerve studies (92516).
Limit one PSG/sleep study procedure per date of service
Only one polysomnography or sleep study procedure may be billed per date of service by the same or different provider; billing more than one PSG/sleep study on the same date risks denial.
Do not bill listed ancillary procedures separately with PSG
Examples of services that will not be paid separately with PSG include 24‑hour ECG monitoring, pulse oximetry, pediatric pneumogram, CPAP initiation/management, EEG, and facial nerve studies—do not bill these separately on the same date as PSG.
Clinical Definitions and Test Descriptions
Background and Clinical Context
Polysomnography (PSG) is a comprehensive sleep study that records sleep staging and multiple physiologic parameters. The policy defines PSG as including EEG, EOG, EMG, ECG (heart rate), measures of airflow and respiratory effort, oximetry/CO2, and additional physiologic measures such as limb activity and body position to support diagnosis and treatment evaluation.
