Monitor payer policy activity
Medicare medical policy governing coverage criteria, documentation, and billing for gender-affirming surgical procedures for Providence Health Plan Medicare members; addresses surgical interventions (not hormones or fertility preservation).
Dermal filler injections for facial lipodystrophy syndrome were removed.
Codes for punch graft hair transplantation and rhytidectomy were added during an interim update.
Reference to Noridian LCD L37020 was replaced with L35163.
Coverage and Medical Necessity
Medical necessity decision framework
Covered when Company medical policy criteria (based on WPATH Standards of Care) are met and when documentation supports medical necessity.
In the absence of an applicable NCD/LCD, Company criteria apply per CFR § 422.101(b)(6) and the Plan's MP50 policy; medical necessity determinations consider the member's diagnoses, functional status, comorbidities, treating clinician recommendations, and clinical documentation, with involvement of a plan medical director as appropriate.
Coverage conditions linked to diagnosis and code type
Covered when billed with appropriate gender dysphoria diagnosis codes and when medical necessity is met per CMS/Noridian guidance
Some codes may be non-covered for other diagnoses or may still require prior authorization for other indications; refer to the policy's Prior Authorization and Non‑Covered code lists.
Providers should submit supporting clinical documentation to demonstrate medical necessity when requesting coverage for unlisted procedures.
This policy addresses only surgical interventions for gender dysphoria/incongruence and does not address hormonal treatments or fertility preservation.
All unlisted CPT/HCPCS codes are reviewed at the claim level for medical necessity, correct coding, and pricing. If an unlisted code is submitted for a service that is non‑covered under this policy, the claim will be denied as not covered.
Services are considered not medically necessary for Medicare when the Company's medical policy criteria are not met. Coverage determinations follow the Company's WPATH‑based criteria and apply Medicare statutory and regulatory requirements in making medical necessity decisions.
The existence of a CPT or HCPCS code, or a payment amount listed in the Medicare Physician Fee Schedule, does not by itself establish that a service is reasonable, necessary, or a covered benefit. Presence of a code or Medicare payment alone is not sufficient to determine medical necessity or coverage.

Prior Authorization, Documentation, and Submission Rules
Prior authorization: codes exempt when billed with F64.x
The following listed CPT/HCPCS codes do not require prior authorization when billed with diagnosis codes F64.0, F64.1, F64.8, or F64.9; other codes or billing with different diagnoses may require prior authorization—see the policy Prior Authorization and Non‑Covered lists. Example exempt codes called out in the policy include: 11920, 11921, 11922, 11950, 11951, 11952, 11954, 15773, 19303, 19318, 19350.
Prior authorization tied to diagnosis codes (F64.x)
Certain listed procedure codes are exempt from prior authorization only when billed with diagnosis codes F64.0, F64.1, F64.8, or F64.9; if billed with other diagnoses, prior authorization may be required and some codes may be non‑covered for other indications.
- When billed with F64.0, F64.1, F64.8, or F64.9 some codes do not require prior authorization
- Prior authorization may be required for other diagnoses; consult the policy's Prior Authorization and Non‑Covered lists
Step/sequence guidance and use of unlisted procedure codes
No step‑therapy requirements are specified in this policy. Providers may need to bill unlisted procedure codes for services without a specific CPT code (for example, laser hair removal, metoidioplasty, or phalloplasty) and should sequence billing accordingly.
- No step therapy required per policy language
- Use unlisted procedure codes when no specific CPT exists (e.g., laser hair removal, metoidioplasty, phalloplasty)
Provider billing/submission note: verify codes and sequences before submission
Submit clinical and billing documentation that supports medical necessity and correct coding; consult code lists and prior authorization guidance to avoid miscoding or inappropriate sequencing.
- Refer to the policy code lists and Prior Authorization/Non‑Covered lists before submission
- Ensure correct CPT/HCPCS selection and sequencing to align with coverage and billing rules
Required clinical documentation and assessment letters
Required documentation includes clinical notes from the operating surgeon plus one assessment letter: for adults (≥18) one letter from a health care professional competent in assessment of transgender and gender diverse people; for adolescents one letter from a multidisciplinary team reflecting both medical and mental health assessment.
- Operating surgeon clinical notes (required)
- Adults: one (1) letter of assessment from a competent health care professional
- Adolescents: one (1) letter from a multidisciplinary team reflecting medical and mental health assessment
Unlisted code documentation and review
All unlisted CPT/HCPCS codes submitted are reviewed at the claim level for medical necessity, correct coding, and pricing; providers should submit supporting documentation to demonstrate medical necessity when using unlisted codes.
- Unlisted codes undergo review for medical necessity, correct coding, and pricing
- Include supporting clinical documentation with unlisted code submissions to justify medical necessity
Missing documentation delays and risk of delayed decisions
Requests will be delayed if required documentation—such as operating surgeon notes and the required assessment letter(s)—are not submitted with the request.
- Missing surgeon clinical notes or required assessment letters will result in delays of prior authorization or coverage determinations
Unlisted code submission: denial risk and recommendation to obtain PA
If an unlisted code is submitted for services that are non‑covered under this policy it will be denied as not covered; for potentially covered services billed with unlisted codes, prior authorization is recommended to avoid post‑service denial.
- Unlisted codes representing non‑covered services will be denied as not covered
- For potentially covered services billed with unlisted codes, obtain prior authorization to reduce risk of post‑service denial
Policy Background and Scope
Historically, Medicare maintained a national coverage determination (NCD) titled “Transsexual Surgery,” which was retired. Since that retirement, coverage decisions for gender‑affirming surgical procedures have been made at the local MAC/LCD level and on a case‑by‑case basis. In the absence of an applicable NCD, this Company's Medicare medical policy uses the WPATH Standards of Care and the Company's internal criteria—along with member‑specific clinical history and applicable Medicare requirements—to guide medical necessity determinations.
