Aural Rehabilitation — CPB 0034 | AETNA Coverage Update

Aetna modified CPB 0034 for aural rehabilitation, effective September 26, 2025. Here's what changes for billing teams.

Aetna, a CVS Health company, updated CPB 0034 — the Aetna aural rehabilitation coverage policy — on September 26, 2025. The policy governs medical necessity determinations for aural rehabilitation services, including auditory verbal therapy (AVT), billed under CPT codes 92626, 92627, 92630, and 92633. If your practice bills post-cochlear implant therapy or hearing loss rehabilitation for Aetna members, this update directly affects your claim submissions.

Quick-Reference Table

Aetna Aural Rehabilitation Coverage Criteria and Medical Necessity Requirements 2025

Aetna covers aural rehabilitation — including auditory verbal therapy — as medically necessary speech therapy under two clear conditions. First, the member has a documented hearing impairment. Second, the member has received a cochlear implant (CPT 69930) and needs post-operative rehabilitation.

That's the covered side. The cutoff is where this policy gets financially important.

Aetna considers aural rehabilitation not medically necessary when a cochlear implant user has reached a plateau in performance. That single phrase — "reached a plateau" — is the denial trigger your billing and clinical teams need to understand before September 26, 2025.

The real issue here is documentation. Aetna's coverage policy doesn't define what "plateau" means in measurable terms. That's deliberate on their part and a problem for yours. If your audiologist or speech-language pathologist isn't documenting continued functional progress at each visit, Aetna has grounds to deny CPT 92626, 92627, 92630, or 92633 on the basis that the patient has plateaued.

Think of this the same way Medicare handles physical therapy caps — the moment documentation stops showing active therapeutic progress, the clinical justification for continued treatment evaporates. The same logic applies here.

Check your prior authorization process for aural rehabilitation services before the effective date. Prior auth requirements for these services vary by plan, and a policy modification on CPB 0034 can trigger changes to prior auth thresholds even when the clinical criteria look familiar. If you're unsure whether prior authorization applies to your Aetna plan mix, call Aetna provider relations or talk to your billing consultant before September 26, 2025.

Aetna Aural Rehabilitation Exclusions and Non-Covered Indications

The exclusion here is narrow but consequential. Aetna will not cover aural rehabilitation billing for cochlear implant users who have plateaued in their performance outcomes.

This isn't an experimental or investigational designation — it's a straight medical necessity denial. That distinction matters for your appeals strategy. You're not arguing that the therapy is proven; you're arguing that the patient hasn't plateaued. Your clinical documentation has to carry that argument.

If a patient's therapy notes are showing flat outcomes across multiple sessions — no measurable gains in speech perception, auditory discrimination, or functional communication — expect Aetna to deny those claims. Document actively and specifically, or don't bill.

Aetna Aural Rehabilitation Billing Guidelines and Action Items 2025

CPT, HCPCS, and ICD-10 Codes for Aural Rehabilitation Under CPB 0034

Covered CPT Codes (When Medical Necessity Criteria Are Met)

Note that +92627 is an add-on code — bill it alongside 92626, never standalone. For aural rehabilitation billing, your primary evaluation code is 92626 for the first hour, then add 92627 for each additional 15-minute increment.

The distinction between 92630 (pre-lingual) and 92633 (post-lingual) matters for accurate diagnosis code alignment. Pre-lingual hearing loss means the hearing loss occurred before speech development. Post-lingual means the member had established speech before losing hearing — which covers most adult cochlear implant recipients. Miscoding this distinction won't necessarily trigger a denial, but it can flag claims for review.

Cochlear Device Supply HCPCS Codes

These HCPCS codes cover cochlear device systems and supplies. They're listed in CPB 0034 as related codes. If your practice bills any of L8614 through L8624, make sure the associated member's therapy authorization is current — a plateau determination on the therapy side can create inconsistencies that trigger supply claim reviews.

Key ICD-10-CM Diagnosis Codes

CPB 0034 lists 297 ICD-10-CM codes. The following are representative codes from the H74 category (other disorders of middle ear and mastoid). Your coding team should select the most specific code that matches the patient's documented condition.

The full list of 297 covered ICD-10-CM codes is available in CPB 0034 at the Aetna policy source. Pull the full code set and cross-check it against your charge capture to confirm your most frequently used hearing disorder codes are included. If a diagnosis code you're using isn't in Aetna's covered list, that's a denial waiting to happen — fix it in your superbill before September 26, 2025.
