Prior Authorization Required and Coverage Variability

Prior authorization is required for the gender-affirming procedures listed in the CPT/HCPCS code sections when applicable and when medical-necessity criteria in this policy are not clearly met. Coverage and prior authorization requirements vary by payer and by the member’s specific benefit plan; always verify benefits before scheduling.

• Prior authorization required for listed CPT/HCPCS codes when medical necessity criteria are not met or unclear
• Coverage varies by plan — check member-specific benefits and plan exclusions

Coverage Determined by Plan Benefits

Authorization and coverage determinations are governed by the member’s benefit plan terms. Even when procedures meet the medical necessity criteria in this policy, coverage is subject to the member’s contract, plan limits, and any applicable Clinical Policy Bulletins (CPBs).

• Benefits, limits, and exclusions in the member’s evidence of coverage control payment
• Clinical Policy Bulletins may further define coverage — verify applicability to the member’s plan

Denial Triggers — Cosmetic or Not Medically Necessary

Services that are cosmetic or otherwise not medically necessary per this policy will be denied. Examples include procedures identified as cosmetic in the policy (e.g., routine facial gender-affirming procedures considered cosmetic, hair removal except for limited preoperative graft preparation, and multiple breast augmentations beyond medically necessary replacement).

• Claims for procedures listed as cosmetic or not medically necessary may be denied
• Elective procedures without documented medical necessity or required documentation are denial triggers

Incorrect CPT Use for Mastectomy (Billing Guidance)

Do not routinely bill mastectomy codes intended for breast cancer (e.g., CPT 19303) for chest masculinization (female-to-male) procedures. Reduction mammaplasty codes (e.g., CPT 19318) describe the work typically performed for chest masculinization and include nipple/areola work that may be incidental to the procedure; use the code that accurately reflects the work performed.

• CPT 19303 is for breast cancer-related mastectomy and is not appropriate for gender-affirming chest procedures
• Use CPT 19318 (reduction mammaplasty) or other codes that reflect performed work for transmasculine chest surgery

Incorrect Use of Nipple Reconstruction Code (Billing Guidance)

Do not report CPT 19350 (nipple/areola reconstruction) at the same operative session when the work performed is included in the primary reduction/mastectomy/reconstruction code (e.g., CPT 19318). CPT 19350 describes a separate, more involved nipple construction and is generally an incidental-to edit when billed with codes such as 19318.

• CPT 19350 is typically incidental to CPT 19318 and should not be separately reported when nipple/areola modification is part of the primary procedure
• When true nipple reconstruction as defined by CPT 19350 is performed as a distinct procedure, document the additional work to support separate reporting

Procedure-Specific Documentation Requirements

Provide procedure-specific documentation to support the chosen CPT/HCPCS code(s) and to describe the extent of work performed. Include operative reports that detail surgical technique, structures addressed, and any grafting or implant work to justify the selected codes.

• Operative report describing technique, tissues removed or preserved, grafts, implants, and intraoperative findings
• If unlisted codes are used, include detailed operative note and rationale for code selection

Mental Health Evaluation and Provider Qualifications

A signed letter from a qualified mental health professional documenting readiness for physical treatments and assessment of marked and sustained gender dysphoria is required for most gender-affirming surgeries. The mental health professional must meet the qualifications described in the Appendix (WPATH SOC-8 guidance).

• Signed readiness assessment letter from a qualified mental health professional (see Appendix for qualifications)
• Documentation of marked and sustained gender dysphoria per DSM-5 criteria

Surgical and Adolescent Provider Qualifications

Surgeons performing gender-affirming procedures should have documented training and experience in gender-affirming surgery, maintain an active practice and outcome tracking, and engage in continuing education per WPATH SOC-8. Providers who treat adolescents must meet the Appendix qualifications for adolescent care.

• Surgeon documentation of training/supervision in gender-affirming procedures and maintenance of active practice
• Adolescent care providers should have postgraduate pediatric/adolescent expertise and training in gender identity development

Hormone Therapy Prerequisites (Provider Action)

Hormone therapy prerequisites must be documented when required by the procedure-specific criteria: typically six months of continuous hormone therapy for adults (12 months for adolescents under 18) as appropriate to the member’s gender goals, unless hormone therapy is not desired or is medically contraindicated.

• Document duration and type of hormone therapy when required (e.g., 6 months feminizing therapy prior to breast augmentation; 6 months appropriate therapy for other procedures)
• If hormone therapy was not desired or was medically contraindicated, include documentation supporting that exception

Preoperative Hormone Therapy Recommendation for Breast Augmentation

For transfeminine persons undergoing breast augmentation, document completion of feminizing hormone therapy for a minimum of six months prior to augmentation (12 months for adolescents), unless hormones are not desired or medically contraindicated. This preoperative hormone therapy is recommended to maximize breast growth and optimize surgical results.

• Record start and end dates of feminizing hormone therapy and any clinical rationale for exceptions
• Preoperative hormone therapy documentation supports clinical decision-making and prior authorization reviews

Required Clinical Documentation for Authorization

Include the following required clinical documentation with requests for authorization: signed mental health readiness letter, documentation of marked and sustained gender dysphoria (DSM-5 criteria), exclusion of other causes of incongruence, assessment of mental/physical comorbidities and capacity to consent, and cancer-risk assessment when applicable. For adolescents, include documentation of hormone therapy duration or contraindication.

• Signed readiness letter from qualified mental health professional
• DSM-5–based documentation of marked and sustained gender dysphoria
• Assessment of other causes, comorbidities, capacity to consent, and cancer risk factors
• Hormone therapy documentation or rationale for exceptions for adolescents

Coverage Administration Note

Coverage decisions and prior authorization processing are administered per the member’s benefit plan and may be further informed by Clinical Policy Bulletins (CPBs). Always reference the applicable CPBs and the member’s plan documents when determining coverage eligibility.

• Verify applicability of related CPBs (e.g., implant removal, cosmetic surgery) to the member’s claim
• Confirm member-specific plan coverage, exclusions, and prior authorization pathways
