Aetna Modified CPB 0034 for Aural Rehabilitation — What Billing Teams Need to Know in 2026
TL;DR: Aetna modified CPB 0034, its aural rehabilitation coverage policy, with an effective date of 2026-03-12. Here's what changes for billing teams.
Aetna, a CVS Health company, updated Clinical Policy Bulletin 0034 governing aural rehabilitation services. This modification affects coverage criteria for hearing-related rehabilitation services billed to Aetna. The policy does not list specific CPT or HCPCS codes in the available data — but if your practice bills for aural rehabilitation services, you need to pull the current version of CPB 0034 and compare it against your charge capture before March 12, 2026.

Aetna Aural Rehabilitation Coverage Criteria and Medical Necessity Requirements 2026
CPB 0034 in the Aetna system governs coverage for aural rehabilitation — a category of services that includes hearing evaluations, hearing aid fittings, auditory training, speech reading, and related therapeutic services following hearing loss diagnosis or cochlear implantation.
The Aetna aural rehabilitation coverage policy ties reimbursement directly to medical necessity. That means Aetna expects documentation showing that the services are clinically indicated, not elective or maintenance-phase care without a clear therapeutic goal.
Medical necessity for aural rehabilitation services under Aetna generally requires a documented diagnosis of hearing loss, evidence that the patient can benefit from rehabilitation, and a treatment plan with measurable outcomes. If your documentation doesn't show functional improvement goals — not just that the patient has hearing loss — you are exposed to claim denial.
Prior authorization requirements for aural rehabilitation services vary by Aetna plan. Some commercial plans require prior auth for ongoing therapy beyond an initial evaluation. Check the specific member's plan documents before you schedule services, not after you've delivered them. Assuming no prior authorization requirement exists is how practices absorb write-offs they could have avoided.
The March 12, 2026 effective date means any claims for dates of service on or after that date are subject to the modified coverage policy. Services billed under the prior version of CPB 0034 criteria — for dates before March 12 — follow the earlier rules. Keep that line clear in your billing system.
Aetna Aural Rehabilitation Exclusions and Non-Covered Indications
Because the available policy data for CPB 0034 does not include the full text of the modification, this section is based on what Aetna's aural rehabilitation coverage policy has historically excluded. Confirm these against the current CPB 0034 document directly.
Aetna has historically excluded hearing aids themselves as a covered benefit under most commercial plans — the device is separate from the rehabilitation services. Billing for the hearing aid and the rehabilitation in the same encounter without clear documentation distinguishing medical services from device costs creates claim denial risk.
Services delivered in the absence of a documented hearing loss diagnosis, or services that amount to maintenance rather than active rehabilitation, typically do not meet medical necessity under Aetna's criteria. Auditory training for patients who have reached a functional plateau — without documentation of a new clinical goal — is a denial waiting to happen.
Experimental or investigational auditory therapies, including certain auditory processing interventions that lack peer-reviewed evidence of clinical effectiveness, are generally excluded. If your practice uses newer protocols, verify coverage before billing.
Coverage Indications at a Glance
The available policy data does not include granular indication-level criteria with specific CPT or HCPCS codes. The table below reflects the general coverage framework for Aetna aural rehabilitation services based on CPB 0034. Verify each row against the current policy text at app.payerpolicy.org/p/aetna/0034. before using this for billing decisions.
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Aural rehabilitation following cochlear implantation | Covered (when medically necessary) | Not specified in available data | Documentation of post-implant functional goals required |
| Aural rehabilitation for documented hearing loss (non-implant) | Covered (when medically necessary) | Not specified in available data | Medical necessity criteria apply; prior auth may be required by plan |
| Hearing evaluation as part of aural rehabilitation plan | Covered (when medically necessary) | Not specified in available data | Must be tied to rehabilitation plan, not standalone screening |
| Maintenance-phase auditory therapy without new clinical goals | Not Covered | Not specified in available data | Does not meet medical necessity criteria |
| Experimental auditory processing interventions | Not Covered / Experimental | Not specified in available data | Confirm specific protocols with Aetna before billing |
| Hearing aid device cost | Not Covered (most commercial plans) | Not specified in available data | Device coverage is plan-specific; bill separately if applicable |
Aetna Aural Rehabilitation Billing Guidelines and Action Items 2026
The modification to CPB 0034 is live on March 12, 2026. That's your hard deadline for updating workflows. Here are the steps your billing team should take now.
| # | Action Item |
|---|---|
| 1 | Pull the current CPB 0034 document from Aetna's provider portal before March 12, 2026. The available policy data here does not include the full modified text. You need the actual document. Go to the source or pull it directly from Aetna's provider resource library. Line-by-line comparison with the prior version will tell you exactly what changed. |
| 2 | Audit your charge capture for aural rehabilitation billing. Identify every CPT and HCPCS code your practice uses for aural rehabilitation services billed to Aetna. Until the full code list from CPB 0034 is confirmed, treat this as a full-category review. Don't assume your existing charge description master (CDM) entries are aligned with the updated policy. |
| 3 | Review your prior authorization workflows for Aetna aural rehabilitation services. If the modification tightened coverage criteria or added new prior auth triggers, claims submitted without prior auth after March 12, 2026 will deny. Contact Aetna provider relations to confirm whether the modification changed any prior authorization requirements for your specific CPT codes. |
| 4 | Update your medical necessity documentation templates. If your providers use standard templates for aural rehabilitation plans of care, review them now. The templates need to capture measurable functional goals, the patient's current hearing status, and a clear clinical rationale tied to the Aetna medical necessity criteria in the updated CPB 0034. Generic templates that don't speak to Aetna's criteria generate denials. |
| 5 | Identify any Aetna members currently mid-course in aural rehabilitation programs. For patients already in treatment, check whether the updated coverage policy affects their ongoing reimbursement. A plan modification that changes visit limits, documentation requirements, or prior auth thresholds can interrupt authorized care mid-episode. Get ahead of this before services are delivered. |
| 6 | Flag any experimental or newer auditory therapy protocols in your service mix. If your audiologists or speech-language pathologists use less standard approaches, verify each one against the updated CPB 0034 exclusion criteria. Claim denial for experimental services is hard to overturn on appeal without strong peer-reviewed clinical support in the record. |
| 7 | Loop in your compliance officer if you're unsure how this modification applies to your patient mix. Aural rehabilitation billing sits at the intersection of audiology, speech-language pathology, and sometimes ENT — which means multiple provider types may be billing under the same policy umbrella. If your practice has more than one specialty involved, have your compliance officer or billing consultant review the updated policy against each service line before the March 12, 2026 effective date. |
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Aural Rehabilitation Under CPB 0034
The available policy data for CPB 0034 does not list specific CPT, HCPCS, or ICD-10 codes. Publishing invented or assumed codes here would be worse than useless — it would send billing teams in the wrong direction.
Here's what to do instead.
Pull the full CPB 0034 document directly from Aetna's provider portal. Aetna's clinical policy bulletins typically include an explicit code table when specific codes are central to the coverage determination. For aural rehabilitation services, the relevant CPT codes generally fall within the audiology and speech-language pathology ranges — but the exact codes Aetna lists, and the coverage status assigned to each, are what matter for your billing team.
Do not substitute general audiology CPT codes from other sources. The codes Aetna specifies in CPB 0034 are the ones that govern reimbursement under this coverage policy. Use those, and only those, when building out your charge capture for Aetna aural rehabilitation claims.
Once you have the full policy document, check back here — or use PayerPolicy's code search to find every policy that references the CPT codes in your charge description master.
