Obstructive Sleep Apnea in Adults — CPB 0004 | AETNA Coverage Update

TL;DR: Aetna, a CVS Health company, modified CPB 0004 — its obstructive sleep apnea coverage policy for adults — effective March 7, 2026. Here's what billing teams need to do.

This update to CPB 0004 in the Aetna system touches a wide range of diagnostic and treatment codes, including polysomnography (CPT 95810, 95811), portable sleep monitoring (CPT 95806, 95800, 95801), hypoglossal nerve stimulator implantation (CPT 64582, 64583, 64584), and surgical procedures from uvulopalatopharyngoplasty (CPT 42145) to mandibular osteotomy (CPT 21198). If your practice bills Aetna for sleep diagnostics, upper airway surgery, or neurostimulator implants, this policy revision directly affects your medical necessity documentation and claim denial risk in 2026.

Aetna Obstructive Sleep Apnea Coverage Policy Criteria and Medical Necessity Requirements 2026

CPB 0004 governs Aetna's obstructive sleep apnea coverage policy from initial diagnosis through surgical intervention. The updated policy draws hard lines between when in-lab testing is required versus when portable monitoring is acceptable — and those lines directly affect your reimbursement.

Attended In-Lab Polysomnography (CPT 95810, 95811)

Aetna considers attended full-channel nocturnal polysomnography (NPSG) — a Type I device study billed as CPT 95810 or CPT 95811 — medically necessary when the member has OSA symptoms AND meets at least one specific clinical criterion. This is not a blanket approval for anyone who snores.

The policy identifies five qualifying pathways for in-lab NPSG:

Pathway 1 — Comorbid conditions that degrade portable monitoring accuracy. The member must have at least one of the following: moderate to severe pulmonary disease (COPD or asthma with nocturnal oxygen use, or daytime hypercapnia with documented ABGs showing pO2 < 60 or pCO2 > 45); neuromuscular disease (Parkinson's, spina bifida, myotonic dystrophy, ALS); stroke with residual respiratory effects; epilepsy; congestive heart failure (NYHA Class III or IV, or LVEF < 45%); pulmonary hypertension (mean pulmonary artery pressure > 25 mmHg); chronic opioid use; or super obesity (BMI > 45, or obesity hypoventilation syndrome defined as BMI > 35 plus ABG PCO2 > 45, or BMI > 35 plus inability to lie flat).

Pathway 2 — Comorbid sleep disorders. Covered when the member has periodic limb movement disorder causing excessive daytime sleepiness, atypical parasomnias (including nocturnal seizures, REM sleep behavior disorder, psychogenic dissociative states, sleep talking, or confusional arousals), severe insomnia, narcolepsy, or central or complex sleep apnea.

Pathway 3 — Failed portable monitoring. If portable monitoring results are negative or technically inadequate, in-lab NPSG is medically necessary.

Pathway 4 — Low pretest probability. Covered when the member has normal BMI (< 30), normal airway (Mallampati score 1 or 2), no snoring, and normal neck circumference (< 17 inches in men, < 16 inches in women).

Pathway 5 — Physical limitations. Covered when the member lacks the mobility or dexterity to use portable monitoring equipment safely at home.

The real issue here is documentation specificity. Each of these pathways requires clinical evidence in the chart. "Patient has COPD" is not enough — you need documented ABGs, NYHA classifications, echocardiographic LVEF values, or Mallampati scores to support the claim. Missing that documentation is a direct path to claim denial.

Split-Night vs. Full-Night Studies

The policy is specific about when a split-night NPSG is appropriate versus a full second-night titration study.

A split-night study is medically necessary when the AHI exceeds 15 in the first two hours of the diagnostic portion. If the AHI is 15 or below in the first two hours — or if the split-night study failed to abolish the vast majority of obstructive events — a full-night CPAP titration NPSG is covered. Both scenarios are billed under CPT 95811 (attended NPSG with CPAP titration).

Portable Home Sleep Testing (CPT 95800, 95801, 95806)

When a member does not meet the criteria above, portable monitoring (Type II–IV devices) is the appropriate starting point. CPT 95800 covers unattended simultaneous recording of heart rate, oxygen saturation, and respiratory analysis. CPT 95801 covers the minimum data set — heart rate, oxygen saturation, and respiratory analysis. CPT 95806 adds ventilation, respiratory effort, ECG or heart rate, and oximetry in an unattended setting.

The attended version of this study — CPT 95807 — adds technician supervision and is covered under separate criteria.

Hypoglossal Nerve Stimulation: CPT 64582, 64583, 64584

Aetna covers implantation of the Inspire System (hypoglossal nerve neurostimulator) under CPT 64582. This requires a prior authorization pathway tied to in-lab NPSG — specifically, the policy states that attended NPSG is medically necessary for members who meet criteria for Inspire System implantation.

Drug-induced sleep endoscopy (CPT 42975) and flexible diagnostic laryngoscopy (CPT 31575) are covered to evaluate appropriateness for hypoglossal nerve stimulation. CPT 64583 (revision or replacement of the respiratory sensor electrode) and CPT 64584 (removal of the full system) are also covered when criteria are met. Post-implant electronic analysis is billed under CPT 95970, with programming under CPT 95976 (simple) or CPT 95977 (complex).

Surgical Interventions

The policy covers a range of upper airway surgeries when members fail other treatment approaches. Uvulopalatopharyngoplasty (CPT 42145) is covered for OSA members who meet specific selection criteria. Glossectomy less than half tongue (CPT 41120) and hemiglossectomy (CPT 41130) are covered under the same framework.

Mandibular and facial procedures — including segmental mandibular osteotomy (CPT 21198), osteoplasty with augmentation (CPT 21208), reduction (CPT 21209), and hyoid myotomy and suspension (CPT 21685) — are covered for OSA members who fail other treatment approaches. Tonsillectomy and adenoidectomy (CPT 42820, 42821, 42825, 42826) and adenoidectomy alone (CPT 42831, 42836) are covered when selection criteria are met.

Nasal procedures — including excision of nasal polyps (CPT 30110–30115), inferior turbinate excision (CPT 30130), submucous resection (CPT 30140), and nasal/sinus endoscopy (CPT 31237–31240) — are covered when airway obstruction contributes to OSA.

Tracheostomy (CPT 31600, 31601) remains a covered last-resort option.

Aetna Obstructive Sleep Apnea Exclusions and Non-Covered Indications

The policy explicitly excludes a large block of nasal and respiratory system procedure codes — CPT 30000 through at least 30033 — for the indications listed in CPB 0004. These are listed in the policy as "CPT codes not covered for indications listed in the CPB."

This is an important distinction. Some of these nasal procedure codes may be covered under other Aetna policies for other indications. But when you're billing them in the context of OSA treatment, they are not covered under CPB 0004. If your claim includes an OSA ICD-10 as the primary diagnosis and one of these non-covered nasal codes, expect a denial.

Aetna Obstructive Sleep Apnea Billing Guidelines and Action Items 2026

Here's what your billing team and revenue cycle staff need to do before claims hit Aetna's adjudication system under this updated policy.

Copy Action Items

If your practice has significant Aetna OSA volume across sleep medicine, ENT, and oral surgery, loop in your compliance officer before the March 7, 2026 effective date to assess your exposure across all three service lines. The breadth of this policy — 238 CPT codes, multiple surgical specialties, and both diagnostic and therapeutic procedures — makes this one of the wider-impact CPB revisions in the sleep medicine billing space.
