Aetna modified CPB 0819 for face transplantation, effective December 4, 2025. Here's what that means for your billing team.
Aetna, a CVS Health company, updated its Aetna face transplantation coverage policy under CPB 0819 in the Aetna clinical policy bulletin system. The policy now explicitly includes cross-gender facial transplantation in its experimental and investigational designation. No CPT or HCPCS codes are listed in the policy — but five ICD-10-CM code ranges tied to head, face, and burn injuries are referenced. If your practice treats patients with severe facial trauma or burns and has ever explored face transplantation billing, this update closes the door firmly.

Aetna Face Transplantation Coverage Criteria and Medical Necessity Requirements 2025
The Aetna face transplantation coverage policy under CPB 0819 is simple: there is no coverage. Aetna does not consider face transplantation — partial or full — to meet medical necessity standards. The procedure is classified as experimental, investigational, or unproven.
That classification means Aetna has determined the safety and effectiveness of face transplantation has not been established to the standard required for reimbursement. This isn't a gray area. The policy doesn't offer a pathway to coverage through prior authorization, clinical criteria, or case-by-case review.
If your team has ever submitted or considered submitting a face transplantation claim to Aetna, understand that no prior authorization will unlock coverage here. The denial isn't an administrative hurdle — it reflects the underlying coverage policy position.
The December 4, 2025 effective date of this modification extended the experimental designation to explicitly include cross-gender facial transplantation. That's the meaningful change in this update. If your billing guidelines didn't previously flag cross-gender cases separately, update them now.
Aetna Face Transplantation Exclusions and Non-Covered Indications
This entire policy is an exclusion. Aetna considers face transplantation experimental, investigational, or unproven across all indications. That includes:
| # | Excluded Procedure |
|---|---|
| 1 | Full facial transplantation |
| 2 | Partial facial transplantation |
| 3 | Cross-gender facial transplantation (explicitly added in this modification) |
The "experimental, investigational, or unproven" designation is the highest-level non-coverage classification Aetna uses. It signals that the payer has reviewed the evidence and found it insufficient — not that the procedure is simply rare or unlisted.
For burn and trauma patients who might seem like ideal candidates clinically, this matters. The ICD-10 codes referenced in the policy — covering severe head and face injuries and burns — are the exact diagnoses that might prompt a reconstructive team to consider facial transplantation. Aetna won't pay for it regardless of diagnosis.
Don't expect this to change soon. Aetna has held this position since the policy was first issued. The December 2025 update adds cross-gender to the exclusion list — it doesn't soften the overall stance.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Full face transplantation | Not Covered — Experimental | S09.8XX+, S09.90X+, S09.93X+, T20.00X+–T20.79X+, T26.00X+–T26.92X+ | No prior authorization pathway exists |
| Partial face transplantation | Not Covered — Experimental | Same ICD-10 ranges | Experimental classification applies regardless of extent |
| Cross-gender facial transplantation | Not Covered — Experimental | Same ICD-10 ranges | Explicitly added to exclusion list in December 4, 2025 modification |
Aetna Face Transplantation Billing Guidelines and Action Items 2025
This policy doesn't create complex billing decisions — it eliminates them. But there are still concrete steps your team should take.
| # | Action Item |
|---|---|
| 1 | Update your internal billing guidelines before December 4, 2025. The effective date has passed. If you haven't already flagged face transplantation as non-covered under Aetna, do it now. Add cross-gender facial transplantation as a specific line item in your non-covered procedures list. |
| 2 | Audit any pending or recently submitted claims tied to the ICD-10 ranges in CPB 0819. The relevant codes — S09.8XX+, S09.90X+, S09.93X+, T20.00X+ through T20.79X+, and T26.00X+ through T26.92X+ — cover severe head trauma and burns. If a claim for reconstructive work sits near these diagnoses and involves transplantation, review it before it generates a claim denial. |
| 3 | Do not submit face transplantation claims to Aetna expecting prior authorization to resolve coverage. Prior auth doesn't exist for this procedure in the Aetna system. Submitting a PA request won't create a coverage pathway — it will waste time and delay patient financial counseling. |
| 4 | Counsel patients directly on financial exposure. If your clinical team is evaluating a patient for face transplantation and that patient carries Aetna coverage, financial counseling should happen before any billing activity. Reimbursement from Aetna is zero for this procedure. Patients need to understand that before the process advances. |
| 5 | Brief your plastic surgery, burn surgery, and transplant surgery coders on the cross-gender addition. This is the specific change in the December 2025 modification. Coders in these specialties need to know that cross-gender cases don't get treated differently — the denial basis is the same, but the explicit policy language is new. |
| 6 | If your institution is part of a face transplantation research program, talk to your compliance officer. Research and clinical trial billing operates under different rules. If face transplantation is being performed under an IRB-approved study, your billing approach changes. Get your compliance officer involved before submitting any claims tied to research activity under Aetna. |

CPT, HCPCS, and ICD-10 Codes for Face Transplantation Under CPB 0819
CPT and HCPCS Codes
The policy does not list specific CPT or HCPCS codes. Aetna's CPB 0819 does not enumerate procedure codes for face transplantation billing. If your team uses unlisted procedure codes or reconstructive surgery codes in connection with face transplantation, those claims will be evaluated under this experimental designation. Do not assume the absence of a specific CPT code creates a billing workaround — it doesn't.
Key ICD-10-CM Diagnosis Codes Referenced in CPB 0819
These are the diagnosis codes Aetna associates with face transplantation scenarios. They cover the clinical conditions most likely to prompt consideration of this procedure.
| 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 on these codes indicates additional characters are required for valid ICD-10-CM coding. Make sure your coders use the most specific available code — not the base code alone.
The T20 and T26 burn ranges are particularly important to flag. Severe burns to the head, face, and eye area are the most common clinical pathway to face transplantation evaluation. If these codes appear on a claim that also involves transplantation procedures, expect a denial under CPB 0819.
