Sinus Surgeries | AETNA Coverage Update

Summary: Aetna, a CVS Health company, modified CPB 0937 covering sinus surgeries, effective April 11, 2026. Here's what billing teams need to know before submitting claims.

Aetna's sinus surgery coverage policy under CPB 0937 has been updated as of April 11, 2026. This policy governs medical necessity criteria, prior authorization requirements, and coverage determinations for sinus surgical procedures billed to Aetna plans. The policy document for CPB 0937 in the Aetna system does not list specific CPT or HCPCS codes in the data available at publication — but that doesn't mean your billing team is off the hook. Read the coverage criteria closely, because medical necessity documentation is where sinus surgery claims live or die.

Aetna Sinus Surgery Coverage Criteria and Medical Necessity Requirements 2026

Aetna's sinus surgery coverage policy under CPB 0937 follows a pattern common to high-volume surgical procedures: the payer ties reimbursement tightly to documented medical necessity, conservative treatment failure, and clinical criteria that must appear in the medical record before the claim gets paid.

For sinus surgeries, that typically means Aetna wants evidence that the patient has chronic sinusitis — not just recurrent acute episodes — and that appropriate medical management has failed. "Failed medical management" isn't a vague phrase here. Aetna expects documentation showing the patient completed an adequate course of antibiotic therapy, nasal corticosteroids, and other conservative measures before surgery was indicated.

Prior authorization is a real exposure point for sinus surgery billing. Functional endoscopic sinus surgery (FESS) and related procedures require prior auth under most Aetna commercial and managed care plans. If your team submits without prior authorization or with incomplete documentation supporting the auth request, you're looking at a claim denial before the procedure even reaches adjudication.

The coverage policy distinguishes between different surgical approaches and indications. Procedures performed for chronic rhinosinusitis with documented polyps, anatomical obstruction confirmed by CT imaging, or recurrent acute sinusitis meeting a defined frequency threshold generally meet Aetna's covered criteria. The key word is "documented." Aetna reviewers will look for CT scan results, symptom duration, and the specific prior treatments tried — and they will deny claims where that documentation is thin or absent from the medical record.

If you're not sure how the updated CPB 0937 criteria map to your patient population's documentation workflow, talk to your compliance officer before April 11, 2026.

Aetna Sinus Surgery Exclusions and Non-Covered Indications

Not every sinus surgery claim will meet Aetna's medical necessity bar under CPB 0937. Several indications consistently fall outside covered status, and billing teams should flag these before submitting.

Surgery performed primarily for cosmetic or aesthetic reasons — including septoplasty or turbinate reduction performed without documented functional impairment — is not covered under the sinus surgery coverage policy. If the medical record reads more like a cosmetic consultation than a functional impairment workup, expect a denial.

Sinus surgery performed for recurrent acute sinusitis that doesn't meet the defined frequency threshold is another common denial trigger. Aetna uses specific criteria around episode frequency and duration. Claims that document two or three acute episodes without meeting the threshold won't survive utilization review.

Experimental or investigational procedures in the sinus category — including some balloon sinuplasty applications beyond first-line covered indications — may be excluded or require additional documentation. This is an area where Aetna has historically tightened criteria, and any update to CPB 0937 should be reviewed for changes to how balloon dilation procedures are classified.

CPT, HCPCS, and ICD-10 Codes for Sinus Surgeries Under CPB 0937

The policy data available at publication does not include specific CPT, HCPCS, or ICD-10 codes from the updated CPB 0937 document. Do NOT use this section as a definitive code list.

The available data for this policy change does not list specific codes. Your billing team should pull the full CPB 0937 policy document from Aetna directly — available at the Aetna Clinical Policy Bulletins library — to get the complete code list for sinus surgery billing under this policy.

What to Look For in the Full Policy Document

When you access CPB 0937, look for the procedure code table covering:

• Functional endoscopic sinus surgery (FESS) codes
• Balloon sinuplasty codes
• Turbinate reduction and septoplasty codes (where billed in conjunction with sinus procedures)
• Relevant ICD-10-CM diagnosis codes for chronic rhinosinusitis, nasal polyps, and recurrent acute sinusitis

These codes are what your charge capture, prior auth requests, and claim submissions will turn on. Get the full list from the source document before April 11, 2026.
