Cigna modified MM 0158 for surgical treatments of obstructive sleep apnea, effective February 20, 2026. Here's what billing teams need to know.
Cigna Healthcare updated its coverage policy for OSA surgical procedures under policy code MM 0158. This revision touches 17 CPT codes and eight HCPCS codes — from hypoglossal nerve stimulator implants (CPT 64582) to palatopharyngoplasty (CPT 42145) to procedures Cigna now explicitly flags as experimental. If your practice or facility bills for any OSA surgical intervention, this update sets the rules for what gets reimbursed and what gets denied.

Cigna Obstructive Sleep Apnea Surgical Coverage Criteria and Medical Necessity Requirements 2026
The Cigna obstructive sleep apnea coverage policy under MM 0158 draws a hard line between covered surgical interventions and those the payer considers experimental. Coverage for the surgical codes listed in this policy is not automatic — Cigna requires that specific medical necessity criteria be met before any of these procedures qualify for reimbursement.
The covered procedures in MM 0158 include mandibular reconstruction surgeries (CPT 21193, 21194, 21195, 21196, 21198, 21199), maxillary osteotomy (CPT 21206), hyoid myotomy and suspension (CPT 21685), palatopharyngoplasty including uvulopalatopharyngoplasty (CPT 42145), drug-induced sleep endoscopy (CPT 42975), and hypoglossal nerve neurostimulator implantation (CPT 64582, CPT 61886, CPT 64568). The associated neurostimulator device codes — HCPCS C1767, C1778, C1787, L8680, L8681, L8686, and L8688 — follow the same coverage logic.
The policy language consistently states coverage is considered only when selection criteria "above are met." That's a direct indicator that prior authorization is almost certainly in play for high-cost procedures like neurostimulator implants. If you bill CPT 64582 or 61886 for Cigna patients without confirming prior authorization status and documented medical necessity, expect a claim denial.
Drug-induced sleep endoscopy under CPT 42975 is included as a covered service when criteria are met. This is significant. DISE has historically sat in a gray zone with many payers. Cigna's inclusion here suggests it accepts DISE as a legitimate diagnostic step in the surgical pathway — but only when used within the framework of the broader OSA surgical evaluation, not as a standalone diagnostic billed outside that context.
Whether Cigna OSA surgical procedures are covered under a given plan also depends on plan-level exclusions. Commercial plan designs vary. Run eligibility and benefit checks on every Cigna patient before scheduling any of these procedures. Reimbursement rates will vary by contract, and medical necessity documentation needs to be airtight before you submit.
Cigna Obstructive Sleep Apnea Surgical Exclusions and Non-Covered Indications
Four codes in MM 0158 carry an explicit "Experimental/Investigational/Unproven" designation for OSA treatment. These are not soft exclusions — Cigna is telling you these procedures won't be covered, and claims billed against them will be denied.
CPT 41512 (tongue base suspension, permanent suture technique) is out. CPT 41530 (submucosal ablation of the tongue base, radiofrequency) is out. CPT 42160 (destruction of lesion, palate or uvula by thermal, cryo, or chemical means) is out. CPT 42299 (unlisted palate/uvula procedure) is also flagged as experimental when used to treat OSA.
On the HCPCS side, C9727 (soft palate implants, minimum of three) is experimental as well.
The real issue here is CPT 42299. It's an unlisted code — meaning it gets used when no specific CPT captures the procedure performed. When Cigna calls out an unlisted code as experimental for OSA, they're closing a door that some billers use to capture newer or off-label palate procedures. Don't assume an unlisted code is a workaround. It's not.
If your surgeons perform radiofrequency tongue base ablation (CPT 41530) or soft palate procedures (CPT 42160, C9727) and your patients are Cigna members, have that conversation before the procedure — not after the denial lands. Informed consent and financial counseling documentation should reflect Cigna's position on these codes under MM 0158.

Cigna Obstructive Sleep Apnea Surgical Billing Guidelines and Action Items 2026
These steps are specific to MM 0158 and the codes it governs. Run through this list before February 20, 2026.
| # | Action Item |
|---|---|
| 1 | Audit your charge capture for all 17 CPT codes and eight HCPCS codes in MM 0158. Confirm that every code maps to the correct clinical scenario. Pay special attention to CPT 64582, 61886, and 64568 — hypoglossal nerve stimulator billing is high-cost and high-scrutiny. |
| 2 | Pull prior authorization requirements for every covered procedure in this policy before scheduling Cigna patients. The policy language signals that selection criteria must be met — that's a prior auth trigger. Call Cigna or check the provider portal for each specific procedure code before the patient goes to the OR. |
| 3 | Remove CPT 41512, 41530, 42160, 42299, and HCPCS C9727 from your OSA surgical charge capture for Cigna patients. These are experimental designations, not coverage limitations you can appeal with additional documentation. The clinical evidence argument isn't going to win here. |
| 4 | Review your DISE documentation under CPT 42975. Cigna covers drug-induced sleep endoscopy billing within the OSA surgical pathway when criteria are met. Make sure your operative and clinical notes connect DISE directly to OSA surgical planning — don't let it look like a standalone diagnostic procedure. |
| 5 | Update your financial counseling scripts for any patient scheduled for a palate or tongue base procedure. If your surgeon prefers radiofrequency tongue base ablation or soft palate implants, Cigna won't cover it. Patients need to know before the procedure, not after the claim denies. |
| 6 | If your billing team handles neurostimulator device components, confirm that HCPCS codes C1767, C1778, C1787, L8680, L8681, L8686, and L8688 are bundled correctly with the implant procedure codes. These device codes follow the coverage status of the procedures they support. Billing them without an approved implant procedure code on the same claim creates exposure. |
| 7 | Talk to your compliance officer if you're unsure how MM 0158's criteria apply to your patient mix. The policy references selection criteria that must be met — but the published summary doesn't spell out every criterion in detail. If your practice does high volume OSA surgical work with Cigna patients, get those criteria mapped against your documentation standards before the effective date. |
