The policy identifies a set of procedures that are considered investigational and not covered. Examples include body contouring unrelated to chest surgery, rib remodeling, buttocks enhancement, tracheal implant, breast lift, buccal fat pad removal, hair transplant, and electrolysis (except when performed for genital surgery preparation). This list is illustrative rather than exhaustive; procedures described as investigational in the policy will be denied when billed under those indications.
Inclusion of a CPT, HCPCS, or ICD code in this policy document is for informational purposes only and does not by itself guarantee member coverage or provider reimbursement. Providers and billing staff must verify coverage by reviewing the member’s specific contract benefits in effect at the time of service.
Coverage for the codes listed in this policy is conditioned on product type and the policy’s medical necessity requirements. The listed codes are considered for coverage only for Commercial Members (Managed Care HMO and POS, PPO, Indemnity) and Medicare HMO Blue / Medicare PPO Blue and only when the policy’s medical necessity criteria on pages referenced are met. Providers must verify member benefits and obtain any required prior authorization.
A subset of CPT codes has been explicitly identified in the policy as investigational for Commercial Members. The policy lists codes including 15771, 15773, 15774, 15839, and 53899 as investigational for the conditions noted; use of these codes for the specified procedures is excluded from coverage as investigational and may trigger denial.
Reconstructive surgery following gender-affirming procedures is considered medically necessary when it is performed to correct complications of the initial surgery or to correct functional impairment resulting from the initial surgery. Reconstructive surgery is not medically necessary when performed solely to reverse natural signs of aging or because the member is dissatisfied with the surgical result.
The policy history documents prior revisions in which certain procedures were newly designated investigational or not medically necessary. Examples include additions and clarifications to the investigational/non-covered list and historic changes to statements on breast lift and electrolysis; these prior actions inform the current non-covered and investigational lists in the policy.
Coverage for the procedures and codes listed in this section is contingent on meeting the policy’s medical necessity criteria (referenced on pages 2–7). If those medical necessity criteria are not satisfied, the listed procedures and associated codes are not covered for the member.
Procedure and Diagnosis Codes
Prior Authorization, Documentation, and Billing Guidance
Prior Authorization Required
Precertification/preauthorization is required for all inpatient procedures described in this policy. For outpatient surgical services, prior authorization requirements vary by product — commercial managed care (HMO/POS), PPO/Indemnity, and Medicare HMO Blue generally require prior authorization for surgical services and fertility preservation; prior authorization is not required for surgically implanted puberty blockers for most products. Use the Prior Authorization Request for Gender Affirming Services (Form #901) or the Electrolysis form (#902) and fax to the numbers provided when seeking authorization.
- Inpatient procedures: precertification/preauthorization IS REQUIRED for all products.
- Outpatient procedures: prior authorization required for surgical services and fertility preservation for Commercial Managed Care (HMO/POS) and PPO/Indemnity; Medicare HMO Blue requires prior authorization for surgical services and select voice/speech services.
- Prior Authorization forms: Form #901 (Gender Affirming Services) and Form #902 (Electrolysis). Fax numbers: Medical and Surgical: 1-888-282-0780; Medicare Advantage: 1-800-447-2994; BCBSMA Employees: 617-246-4299.
Use Listed ICD-10-PCS Codes for Authorization Requests
When submitting authorization requests for inpatient procedures or when prior authorization is required for outpatient procedures, include the exact ICD-10-PCS procedure codes from the policy (e.g., the listed ranges for gender-affirming facial surgery and female-to-male procedures). Use the ICD-10-PCS codes provided in the policy when seeking authorization if required.
- Use the listed ICD-10-PCS codes for gender-affirming facial surgery and FTM procedures (see policy code lists).
- Precise procedure coding reduces claim processing issues and supports the authorization review.
Investigational CPT Codes — Potential Denial
Certain CPT codes are designated investigational for Commercial Members; prior authorization may be required but coverage is not provided for investigational procedures and authorization requests for these CPT codes are likely to be denied.
Medical Necessity Required for Coverage; No Separate Authorization Acceptance Criteria in Code Lists
Coverage for the listed surgical procedure codes is contingent upon meeting the medical necessity criteria (Table 1 and Table 2). The policy excerpt with the code lists does not itself provide additional authorization acceptance or explicit denial criteria beyond requiring that medical necessity criteria be met.
- The code lists are informational; inclusion does not guarantee coverage — the medical necessity criteria must be documented and met.
- The policy code lists do not specify separate authorization acceptance thresholds or explicit denial criteria beyond the medical necessity requirements.
Adolescent-Specific Documentation Required
For members under 18, providers must submit additional documentation when requesting surgery. This must demonstrate adequate home support, realistic expectations about surgical outcomes and long-term consequences, and assessment of co-existing mental health concerns; surgery for adolescents is considered on a case-by-case basis.
- Required adolescent-specific documentation: adequate home support; realistic expectations and understanding of long-term consequences; assessment and documentation of co-existing mental health concerns showing surgery is not an initial response to gender-dysphoric puberty.
- Members <18 are evaluated individually and additional evidence is required to justify medical necessity for surgery.
Diagnosis and Criteria Required on Claims
When submitting claims or authorization requests, include an ICD-10 diagnosis from the F64.x series (e.g., F64.0–F64.9) to correspond with the CPT/HCPCS/ICD-10-PCS procedure codes and demonstrate that the medical necessity criteria have been met.
- Required diagnosis codes: F64.0, F64.1, F64.2, F64.8, F64.9 when appropriate and supported by documentation.
- Documentation must support that the member meets Table 1 and Table 2 medical necessity criteria when submitting the procedure codes.
Code Lists Do Not Replace Required Clinical Documentation
The policy excerpts that list codes do not include full documentation templates or an exhaustive list of required supporting records; providers must still supply all clinical documentation demonstrating that the member meets the medical necessity criteria (e.g., provider notes, behavioral health letters, hormone therapy history where applicable).
- Code lists alone are not sufficient — include clinical records, letters of support, hormone therapy documentation, and any other evidence required by Table 1/Table 2 or product-specific authorization rules.
- If documentation demonstrating medical necessity is not provided, authorization or claims may be denied.
Step Therapy / Medication Sequencing
Step therapy and medication sequencing are not specified in this policy excerpt. Puberty blockers and gender-affirming hormone therapies are covered at the discretion of the treating provider and may be subject to formulary or tiering restrictions as applicable to the member's benefit plan.
- No step therapy requirements are listed in this excerpt for puberty blockers or hormone therapies.
- Coverage of medications remains subject to the member's pharmacy benefits, formulary placement, and any prior authorization requirements for the specific drug codes (note: certain HCPCS injection codes are exempt from prior authorization as noted in the policy).
Clinical Background and Scope
Gender dysphoria describes a marked incongruence between assigned sex at birth and the individual’s experienced gender identity. Treatment options addressed in this policy include puberty suppression, gender-affirming hormone therapy, behavioral health and voice services, fertility preservation, and surgical interventions. The policy references accepted standards (for example WPATH) as part of recommended minimum criteria for some services.
