Optic Nerve Decompression Surgery — CPB 0415 | AETNA Coverage Update

Aetna modified CPB 0415 covering optic nerve decompression surgery, effective September 26, 2025. Here's what billing teams need to know.

Aetna, a CVS Health company updated its optic nerve decompression coverage policy under CPB 0415 in the Aetna system. The policy now defines four specific indications that qualify for medical necessity under CPT 67570 and CPT 31294. If your practice performs optic nerve decompression surgery and bills Aetna, your documentation and coding processes need to reflect these criteria before submitting claims.

Aetna Optic Nerve Decompression Coverage Criteria and Medical Necessity Requirements 2025

The Aetna optic nerve decompression coverage policy under CPB 0415 is narrow. Aetna considers the procedure medically necessary for only four indications. If your patient's diagnosis doesn't fit one of these four, expect a claim denial.

Here are the four covered indications:

Two CPT codes cover this procedure: CPT 67570 (optic nerve decompression via incision or fenestration of the optic nerve sheath) and CPT 31294 (nasal/sinus endoscopy, surgical, with optic nerve decompression). Both codes are covered when the selection criteria are met. CPT 31294 applies specifically to the navigator-assisted trans-nasal endoscopic approach.

The policy does not explicitly mention prior authorization requirements within the CPB 0415 text itself. However, given that both CPT 67570 and CPT 31294 are surgical procedures with narrow medical necessity criteria, run a prior authorization check through Aetna's portal before scheduling. Skipping that step on a procedure this specific is a reimbursement risk you don't want to take.

Aetna Optic Nerve Decompression Exclusions and Non-Covered Indications

This is where the policy gets important for billing teams. The CPB 0415 Aetna system policy lists no additional covered indications beyond the four above. That means conditions you might expect to see covered — including non-arteritic anterior ischemic optic neuropathy (NAION) and traumatic optic nerve injury — are not on the covered list.

Look at the ICD-10 codes included in the policy data. You'll see H47.12 through H47.19, which describe ischemic optic neuropathy (NAION). These codes appear in the policy's code table, but NAION is not listed as a covered indication in the medical necessity criteria. The same is true for H47.321–H47.329 (drusen of optic disc), H53.8 (intermittent paroxysmal unilateral phosphenes), and the S04.011A–S04.019S range (injury of optic nerve).

The real issue here is that a code appearing in a policy's ICD-10 table does not automatically mean coverage. It means Aetna recognizes the code in the context of this procedure — likely as a submitted diagnosis — but the coverage decision still hinges on whether the documented indication matches the four criteria above. If you submit CPT 67570 with a NAION diagnosis code and no documentation tying the clinical picture to one of the four covered indications, you're looking at a denial.

Talk to your compliance officer if your practice treats NAION or traumatic optic neuropathy patients and has been billing Aetna for decompression under this policy. The gap between what's in the code table and what's in the covered indications list creates real exposure.
