Aetna modified CPB 0819 for face transplantation, effective December 4, 2025. Here's what billing teams need to know.
Aetna, a CVS Health company, updated its Aetna face transplantation coverage policy under CPB 0819 in the Aetna system, maintaining the procedure's classification as experimental, investigational, or unproven. The policy explicitly covers both standard and cross-gender facial transplantation under the same blanket exclusion. No CPT or HCPCS procedure codes are listed in the policy data — but five ICD-10-CM diagnosis code ranges are referenced, and those are the codes your team needs to monitor for claim denial triggers.

Aetna Face Transplantation Coverage Criteria and Medical Necessity Requirements 2025
The Aetna face transplantation coverage policy under CPB 0819 is straightforward: there is no medical necessity pathway that gets this procedure covered. Aetna does not recognize face transplantation as medically necessary under any diagnosis or clinical scenario.
This matters for billing teams because "experimental or investigational" is not the same as "non-covered for now." It means Aetna has reviewed the evidence and determined the safety and effectiveness of face transplantation has not been established. That determination drives a hard denial — not a prior authorization workflow, not a peer-to-peer opportunity.
If a patient or provider asks whether prior authorization could open a coverage pathway, the answer here is no. Prior auth exists to confirm medical necessity before a service. When the coverage policy itself says the procedure is experimental, there is no medical necessity to confirm. Prior auth requests for face transplantation under Aetna plans will be denied at the authorization stage, before a claim is ever submitted.
The real issue for billing teams is managing expectations — with providers, patients, and referring facilities — before services are rendered.
Aetna Face Transplantation Exclusions and Non-Covered Indications
This entire policy is an exclusion. Aetna considers face transplantation experimental, investigational, or unproven. That classification applies to:
| # | Excluded Procedure |
|---|---|
| 1 | Standard face transplantation — full or partial facial allotransplantation regardless of indication |
| 2 | Cross-gender facial transplantation — explicitly named in the policy, covering scenarios where donor and recipient are of different genders |
The policy does not carve out any subpopulation — not burn victims, not trauma patients, not patients with severe disfigurement from disease. The experimental designation is blanket.
This is consistent with how most major payers treat vascularized composite allotransplantation (VCA) procedures broadly. Face transplantation billing is not a gray area under CPB 0819. Any claim submitted to Aetna for face transplantation should be expected to generate a claim denial.
The diagnosis codes referenced in the policy — primarily burn and trauma ICD-10 codes — describe the patient populations most likely to be evaluated for this procedure. The presence of those codes in the policy is not a coverage signal. It is a framework for identifying which claims fall under this exclusion.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Face transplantation (standard) | Experimental / Not Covered | S09.8XX+, T20.00X+–T20.79X+ | No medical necessity pathway; expect denial |
| Cross-gender facial transplantation | Experimental / Not Covered | S09.8XX+, T20.00X+–T20.79X+ | Explicitly named in policy |
| Face transplantation following burn injury | Experimental / Not Covered | T20.00X+–T20.79X+, T26.00X+–T26.92X+ | Burn diagnosis does not create coverage |
| Face transplantation following trauma | Experimental / Not Covered | S09.8XX+, S09.90X+, S09.93X+ | Trauma diagnosis does not create coverage |
Aetna Face Transplantation Billing Guidelines and Action Items 2025
The December 4, 2025 effective date is already past. If your team hasn't reviewed workflows against this updated policy, do it now.
| # | Action Item |
|---|---|
| 1 | Flag face transplantation procedures as non-covered in your charge capture system. There is no Aetna reimbursement pathway for these services. Any CPT code associated with facial allotransplantation submitted to Aetna against these ICD-10 diagnosis codes will be denied. |
| 2 | Update your pre-service financial counseling scripts for affected diagnosis codes. Patients presenting with burns (T20.00X+–T20.79X+, T26.00X+–T26.92X+) or head and face trauma (S09.8XX+, S09.90X+, S09.93X+) who are being evaluated for face transplantation need to hear clearly that Aetna plans will not cover this procedure. |
| 3 | Do not submit prior authorization requests for face transplantation to Aetna. The policy's experimental designation means Aetna will deny at the PA stage. Submitting a PA request wastes administrative time and can delay the patient's overall care planning. |
| 4 | Audit any pending or recently submitted face transplantation claims. If your billing team submitted claims before December 4, 2025 under an older version of CPB 0819, review those accounts. The experimental classification has been maintained in this modification, so denial logic has not changed — but confirm no claims are sitting in limbo. |
| 5 | Document the financial counseling conversation. When you advise a patient that face transplantation is not covered under their Aetna plan, document it in the medical record and the billing file. If the patient chooses to proceed, obtain a signed Advance Beneficiary Notice equivalent (an out-of-pocket acknowledgment for commercial plans) before services are rendered. |
| 6 | If your practice is evaluating face transplantation as part of a research protocol, loop in your compliance officer before billing. Research billing rules are separate from standard clinical billing guidelines, and the experimental designation may affect how you code and bill evaluation services tied to an IRB-approved study. |
The bottom line on face transplantation billing under Aetna: this is a zero-reimbursement procedure under all current plan types. Build your workflows around that reality.
| 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 Face Transplantation Under CPB 0819
CPT and HCPCS Procedure Codes
CPB 0819 does not list specific CPT or HCPCS procedure codes. The policy addresses face transplantation categorically as experimental and does not map coverage criteria to specific procedure codes. If your team bills reconstructive or transplant procedures that could be interpreted as facial allotransplantation, your compliance officer should review those codes against this policy before submission.
Key ICD-10-CM Diagnosis Codes
These are the exact codes referenced in CPB 0819. They represent the patient populations most likely to be evaluated for face transplantation. Their presence in this policy reflects exclusion scope — not coverage.
| Code | Description |
|---|---|
| S09.8XX+ | Other specified injuries of head |
| S09.90X+ | Unspecified injury of head and face |
| S09.93X+ | Unspecified injury of head and face |
| T20.00X+–T20.79X+ | Burn and corrosion of head, face, and trunk |
| T26.00X+–T26.92X+ | Burn and corrosion confined to eye and adnexa |
The "+" notation indicates these are placeholder characters — your coding team needs to assign the appropriate 7th character extension based on encounter type (initial encounter, subsequent encounter, or sequela) per ICD-10-CM guidelines.
The burn code ranges (T20 and T26) cover both thermal and chemical burns across severity levels. A patient with severe facial burns from a T20 or T26 code is exactly the clinical profile Aetna is accounting for in this policy — and the policy is explicit that even that presentation does not establish coverage.
