Provider Actions & Requirements

Prior Authorization

Prior Authorization Required

Authorizations are required for elective gender transition/affirmation surgeries and related services. Authorizations are valid for 12 months from the date of approval. If the authorized service is not completed within 12 months, a new authorization must be submitted. Submit authorization requests through the payer's standard prior authorization process and include all required documentation per policy.

Authorizations valid 12 months from approval date
New authorization required if procedure not completed within 12 months
Submit prior authorization requests via the payer's standard process

Documentation Required

Mental Health Recommendation — content & timing

A qualifying letter or supporting documentation from a licensed mental health professional is required for many procedures (see policy-specific criteria). The documentation must confirm the diagnosis of gender dysphoria and recommend or support the requested surgery or procedure. For prospective requests, the letter or medical record documentation must be based on a pre-surgery evaluation, psychotherapy, or treatment conducted within the last 12 months. For retrospective requests, the documentation must be based on an evaluation, psychotherapy, or treatment in the 12 months immediately preceding the surgery. Clinicians providing the recommendation must meet the licensing/qualification requirements described in this policy (licensed mental health professional). A 2-year reuse exception for letters may apply when specifically allowed by the policy—verify the applicable guideline in the documentation requirements section.

Background & Evidence

Gender transition/affirmation surgery is intended to align a person's sexual characteristics (genitals, breasts, and in some cases face or trunk) with their identified gender and is typically performed after diagnosis of gender dysphoria and completion of preparatory treatments (counseling, consideration of hormone therapy when desired, and readiness assessment).

The policy lists covered procedures (top and bottom surgeries, augmentation mammoplasty, facial/body procedures, hair removal, voice surgery, medical tattooing, and related facility/anesthesia charges) and the criteria required for coverage. This policy applies only when the individual's Plan includes these benefits; consult the member contract or customer service for plan-specific coverage, customized criteria, or exclusions.

Evidence source	Key point
WPATH SOC v7
Defines transsexualism criteria including persistent identification and >=2 years persistence as threshold for consideration
Hormone therapy presurgery evidence
Evidence is very low quality for presurgery hormone therapy in adults; no credible evidence it improves surgical or psychiatric outcomes
Breast augmentation studies (2022-2023)
Two observational studies (n=181 total) suggested limited clinical value of pre-augmentation hormone therapy; surgical augmentation improved feminine self-perception and QoL
Adolescent evidence reviews
Systematic and national reviews conclude evidence for adolescent gender-affirming surgery is weak to insufficient; WPATH v8 supports adolescent interventions but acknowledges limited evidence
Update 2023 references added
2023 updates removed hormone therapy prerequisite for augmentation mammoplasty and added investigational status for uterine and penile transplantation with supporting references

Site of service: the location where the surgical procedure is performed (examples: off‑campus outpatient hospital/medical center, on‑campus outpatient hospital/medical center, ambulatory surgical center, or inpatient hospital/medical center).

Qualifying mental health recommendation: a recommendation or support (letter or medical record documentation) that meets the policy's minimum content requirements (supports the specific proposed surgery or gender transition surgery in general; specifies dates of evaluation/treatment within the prior 12 months or demonstrates frequency showing recent evaluation; confirms diagnosis of Gender Dysphoria and documents persistence or other transition actions; assesses comorbidities and decision‑making capacity).

Gender dysphoria / transsexualism: per referenced standards (WPATH/DSM), marked incongruence between experienced/expressed gender and assigned gender with persistence and clinically significant distress/impairment (WPATH v7 characterization and DSM‑5 criteria referenced).

Qualifying mental health recommendation reuse definition: a mental health recommendation that meets the policy's specified documentation elements and timing such that a new recommendation is not required for subsequent surgery/procedure requests made within 2 years of a prior qualifying recommendation/authorization (subject to the policy's timing rules and exceptions).

Not Covered / Investigational

Other not medically necessary determinations: surgery to reverse a prior gender transition/affirmation procedure is generally considered not medically necessary except when there is a serious medical barrier to completing transition, the development of a serious medical condition necessitating reversal, or when a complication is causing or likely to cause a medical/surgical emergency.

Revisions, corrections, or repairs are considered not medically necessary when the original surgery was determined to be not medically necessary. Exceptions exist for corrective surgery that addresses complications causing pain or functional impairment or is likely to cause such impairment, and when documentation shows the prior surgery met applicable criteria at the time it was performed.

Revision History

2016-05-01age_threshold_affirmed

Minimum age for gender transition/affirmation surgery affirmed as 18 years (rationale cites developmental maturity and brain maturation literature).

2023-01-01hormone_prerequisite_removed

Removed requirement for hormone therapy prior to augmentation mammoplasty/breast augmentation; augmentation may be via implants, fat transfer, or both.

2023-10-01mh_timing_changed

Timing requirement for mental health recommendation/support changed: recommendations/support must be based on evaluation/treatment within the last 12 months (increased from 6 months); single letter acceptable for genital surgery (changed from two).

On This Page

All of the following for initial augmentation mammoplasty/breast augmentation (male-to-female): one letter of recommendation or medical record documentation from a licensed mental health professional based on a pre-surgery evaluation or psychotherapy/mental health treatment within the last 12 months (for retrospective requests, documentation must be from the 12 months immediately preceding the surgery); diagnosis of gender dysphoria confirmed by the licensed mental health professional; individual is aged 18 years or older.

Nipple reconstruction or areolar procedures may be part of reconstruction following covered chest/breast surgery when clinically appropriate.

Operator grouping 'any' for additional/secondary breast procedures: additional breast augmentation following an initial augmentation mammoplasty and other breast/chest cosmetic procedures for feminization, masculinization, or non-binary transition are considered under the same documentation and medical necessity review as initial procedures and require mental health documentation as specified unless plan language states otherwise.

Genital ("bottom") surgery

Any of the following for clitoroplasty, hysterectomy, and vaginoplasty when indicated: one letter of recommendation or medical record documentation from a licensed mental health professional based on a pre-surgery evaluation or psychotherapy/mental health treatment conducted within the last 12 months (for retrospective requests, documentation must be from the 12 months immediately preceding the surgery); diagnosis of gender dysphoria confirmed by the licensed mental health professional; individual is aged 18 years or older.

Any of the following other genital procedures are listed as potential gender transition/affirmation surgeries subject to plan coverage and documentation requirements: labiaplasty; metoidioplasty; orchiectomy; penectomy (male-to-female or as appropriate for male-to-non-binary); penile prostheses for female-to-male patients; phalloplasty; placement of testicular prostheses for female-to-male patients; salpingo-oophorectomy; scrotoplasty; urethroplasty; vaginectomy.

Operator 'any' applies: at least one of the above genital procedures may be requested and each is reviewed against the policy's documentation, mental health, age, and timing requirements.

Hair removal

All of the following for hair removal related to genital surgery: hair removal (laser or electrolysis) when required to prepare donor tissue or surgical fields for genital reconstruction is medically necessary when performed in conjunction with or prior to covered genital surgery per the timing and documentation requirements in this policy.

All of the following for facial/body/extremity hair removal for feminization or non-binary transition: hair removal (laser or electrolysis) for feminization or non-binary gender-affirming care of the face, body, or extremities is medically necessary when documented as part of the gender transition plan and when performed by approved provider types in appropriate settings; this branch removes a separate mental health recommendation requirement when the procedure is for feminization/non-binary care (see Hair removal (facial/body/extremity and pre-genital surgery) for provider requirements).

Not medically necessary: non-genital hair removal solely for masculinization (e.g., chest or body hair removal for masculinizing goals) is considered not medically necessary under this policy unless contract language specifies otherwise.

Medical tattooing

All of the following for medical tattooing: tattooing performed in conjunction with or after an authorized gender transition/affirmation surgery to restore or reconstruct appearance (for example, areola tattooing after breast reconstruction or pigmentation to improve surgical outcomes) is medically necessary when the intent is restorative/reconstructive and the procedure is performed by qualified practitioners in appropriate settings; timing must be in conjunction with or following an authorized and covered surgery.

Uterine and penile transplantation

Uterine and penile transplantation (Investigational/Not covered)

Any of the following are considered investigational and not covered: uterine transplantation; penile transplantation.

Revision, correction, reversal, and complications

All of the following for revisions due to dissatisfaction: revision surgery to address patient dissatisfaction when the original procedure was performed for gender transition/affirmation and met the policy criteria at the time it was performed may be considered medically necessary when the revision is to correct a functional problem or anatomic complication rather than solely for cosmetic dissatisfaction; documentation must demonstrate functional impairment or complication.

All of the following for correction of incomplete or incorrectly performed surgery: procedures to complete an incomplete transition surgery or to correct incorrectly performed surgery are medically necessary when documentation shows the previous surgery did not achieve intended, durable functional or anatomic outcomes and the original procedure met coverage criteria at the time it was performed.

All of the following for reversal procedures: reversal of prior gender transition/affirmation surgery may be considered medically necessary when clinically indicated and when documentation supports medical necessity; if the original surgery was covered and met criteria at the time, reversal may be covered subject to medical necessity review.

All of the following for correction/repair of complications: procedures to diagnose or treat surgical complications (including infection, hemorrhage, wound dehiscence, prosthesis complications, or other complications) are medically necessary when they address a documented complication. Emergency or urgent procedures to address complications may be authorized without meeting standard preoperative mental health letter timing requirements; however, documentation of the complication and emergent indication must be provided.

Operational note: For coverage of revisions, corrections, or reversals, the policy requires that any prior gender transition/affirmation surgery being revised or reversed met the policy's criteria at the time it was originally performed; exceptions are limited to genuine emergencies or when the Plan authorizes otherwise.

Preservation of fertility

All of the following: procurement, cryopreservation, and storage of sperm, oocytes, and/or embryos prior to gender transition/affirmation surgery are medically necessary when performed to preserve fertility before procedures that may impair reproductive capacity. Exception: services are not covered for plans that do not include assisted reproduction benefits per the member contract.

Non-surgical services cross-references

Refer to the following medical policies for non-surgical gender-affirming services: voice therapy and speech therapy (see related medical policy for voice/communication services); hormone therapy (refer to endocrine/pharmacy policies and 5.01.625 Gonadotropin Releasing Hormone (GnRH) Analogs where applicable); counseling and behavioral health services (refer to mental health benefits and counseling policies).

Recommendations by Licensed Mental Health Professionals - requirements

All of the following are required in letters/recommendations from licensed mental health professionals supporting gender transition/affirmation surgery or procedures: clear statement of the professional's licensure and qualifications; documentation that the clinician has evaluated the patient and confirmed diagnosis of gender dysphoria; description of relevant mental health treatment or psychotherapy and dates; confirmation that the patient has capacity to consent to surgery; assessment and documentation of stability of any comorbid psychiatric disorders and that these are reasonably managed such that they do not contraindicate surgery; statement of the specific procedure(s) recommended and clinical rationale linking procedure to gender dysphoria treatment; attestation that the clinician has discussed risks, benefits, and alternatives.

Clinician qualifications: licensed mental health professionals include psychiatrists, psychologists, licensed clinical social workers, licensed professional counselors, or other licensed behavioral health clinicians as defined by state law and the Plan. Co-signature: trainees may contribute to documentation but the supervising licensed clinician must sign and provide credentials unless plan permits specific co-signature exceptions. Virtual visits: evaluations and recommendations may be provided via telehealth/virtual visit provided they meet the same documentation standards and the clinician is licensed to practice in the state where the patient resides or as allowed by applicable law/regulation.

Timing requirements for mental health recommendations

Any of the following: standard timing requirement is that mental health evaluations/recommendations used to support prospective surgical authorization must be based on evaluation or psychotherapy within the prior 12 months; retrospective requests must have documentation from the 12 months immediately preceding the surgery.

Exception branch: a two-year exception may be considered when the licensed mental health professional provides clear documentation explaining why a more remote evaluation (up to 24 months) remains clinically valid; however, unless the two-year exception is applied, letters older than 12 months do not meet the standard requirement.

Authorization validity: prior authorization for a surgery is valid for 12 months. If the operation is not performed within 12 months, a new authorization request must be submitted and all required documentation, including updated mental health recommendations if over 12 months old, must be provided.

DSM-5 criteria reference for Gender Dysphoria (adults/adolescents)

DSM-5 summary for adults: marked incongruence between experienced/expressed gender and assigned gender lasting at least 6 months, manifested by clinically significant distress or impairment in social, occupational, or other important areas of functioning; presence of at least two specified indicators (e.g., strong desire to be of another gender, strong desire for primary/secondary sex characteristics of another gender, strong desire to be treated as another gender).

DSM-5 summary for adolescents: similar diagnostic criteria adapted for adolescents, including marked incongruence lasting at least 6 months with clinically significant distress or impairment, and relevant age-appropriate indicators as listed in DSM-5. These DSM-5 criteria are referenced for diagnostic confirmation by licensed mental health professionals providing recommendations.

Authorizations

All of the following: prior authorizations are valid for 12 months from the date of approval; if the authorized surgery is not completed within 12 months, a new authorization is required and all policy requirements, including updated mental health documentation if older than 12 months, must be met for each new request; exceptions to re-submission of mental health documentation may be considered only when the Plan documents a standing exception (for example, urgent/emergent procedures or specific two-year mental health exception documented by the clinician).

Site of service for elective surgical procedures

All of the following sites are considered medically necessary for elective gender transition/affirmation surgical procedures when appropriate: off campus-outpatient hospital/medical center; on campus-outpatient hospital/medical center; ambulatory surgical center.

Inpatient hospital/medical center is considered medically necessary only when the patient has clinical conditions that increase the risk for complications, including any of the following: anesthesia risk (personal history of complication of anesthesia; documentation of alcohol dependence or history of cocaine use); prolonged surgery > 3 hours; cardiovascular risks (uncompensated chronic heart failure NYHA class III or IV; recent MI < 3 months; poorly controlled, resistant hypertension defined as requiring 3 or more drugs; recent cerebrovascular accident < 3 months; increased risk for cardiac ischemia such as drug-eluting stent placed <1 year or angioplasty <90 days; symptomatic cardiac arrhythmia despite medication; significant valvular heart disease); liver risk (advanced liver disease, MELD score > 8); pulmonary risk (COPD with FEV1 < 50%; poorly controlled asthma with FEV1 < 80% despite treatment; moderate to severe OSA with AHI ≥15); renal risk (end stage renal disease on dialysis); other risks including morbid obesity (BMI ≥ 50), pregnancy, bleeding disorder requiring replacement factor or blood products (DDAVP does not meet this criterion), or anticipated need for transfusion(s).

Not medically necessary: inpatient hospital/medical center site of service is not medically necessary for elective procedures when the above inpatient criteria are not met.

Clinical thresholds and requirements (background and updates)

WPATH references: care and recommendations are informed by standards such as WPATH SOC; policy aligns with established professional guidance while applying Plan-specific documentation and medical necessity criteria.

Minimum age statement: individuals must be aged 18 years or older for procedures requiring age minimum per this policy unless contract language or specific policy section provides otherwise.

Hormone therapy position: hormone therapy is not universally required prior to surgery under this policy; absence of hormone therapy does not by itself preclude coverage when other criteria are met and when plan language does not mandate hormone therapy.

Investigational procedures note: certain procedures (for example uterine and penile transplantation) are considered investigational and not covered.

Adolescent evidence summary: evidence for adolescents is limited; when adolescent procedures are considered, documentation and criteria must follow both this policy and applicable pediatric/adolescent standards and contract terms; additional review may be required.

Timing and validity of authorizations and mental health recommendations

All of the following: prior authorizations are valid for 12 months; mental health recommendations used to support authorization must be current within 12 months unless a documented two-year exception is applied by the licensed mental health professional; if surgery is not performed within 12 months of authorization, a new authorization and updated documentation are required for subsequent requests.

Hair removal (facial/body/extremity and pre-genital surgery)

All of the following: approved provider types for laser/electrolysis hair removal include licensed physicians, physician assistants, nurse practitioners, registered nurses, licensed practical nurses under supervision as allowed by state law, or licensed electrologists where state regulations permit; services should be performed in appropriate clinical settings or accredited facilities when required by state law or local regulations.

Settings and provider rules: hair removal performed in medical settings by qualified clinical providers is covered when medically necessary for pre-operative preparation of donor sites or when performed for feminization/non-binary transition goals as described in the Hair removal criteria; services performed at spas or non-licensed facilities are not covered unless performed by an appropriately licensed provider operating within their scope of practice and as allowed by the Plan.

Mental health requirement removal: when hair removal is for facial/body/extremity feminization or non-binary transition (non-genital), the separate mental health recommendation requirement is removed per policy branch; pre-genital hair removal (to prepare donor tissue/surgical field) remains considered medically necessary and tied to an authorized surgery.

Surgery revisions, corrections, complications, and reversal

All of the following policy clarifications: coverage for revisions, corrections, and reversals requires that the original gender transition/affirmation surgery met the policy's coverage criteria at the time it was performed; if the prior surgery did not meet policy criteria when performed and was not authorized by the Plan, subsequent revision/reversal requests are evaluated and are generally not covered except in emergencies or when the Plan approves coverage for other reasons.

Emergency exceptions: procedures required to address acute surgical complications or life/limb/threatening conditions may be authorized regardless of prior authorization status; documentation must support the emergent nature of the intervention.

Documentation requirements: for revision/correction/reversal requests include operative reports from the original procedure, current clinical evaluation describing the problem or complication, and supporting imaging or specialist evaluations as needed to justify medical necessity.

Mental health recommendations and documentation requirements

All of the following required elements in mental health documentation: clinician identification and licensure; statement confirming diagnosis of gender dysphoria per DSM-5 criteria; description of history and duration of gender dysphoria symptoms; summary of relevant mental health treatment or psychotherapy and dates; assessment of co-occurring psychiatric conditions and documentation they are sufficiently stable or treated to proceed with surgery; confirmation of informed consent capacity; explicit statement recommending the specific surgical procedure(s) and medical rationale linking the procedure to treatment of gender dysphoria; dates of evaluation(s) and signature of the licensed clinician.

Virtual visits and licensing: telehealth/virtual evaluations are acceptable if the clinician is licensed to provide services in accordance with state law and the evaluation meets all documentation standards; trainees may participate but a licensed supervisor must sign unless otherwise permitted.

Comorbid psychiatric disorders handling: documentation must address co-occurring disorders and provide clinical justification that such conditions do not contraindicate surgery or are being managed to a level compatible with proceeding.

Clinical items and miscellaneous coverage clarifications

Hormone therapy: hormone therapy prior to surgery is not universally required by this policy and lack of hormone therapy alone does not preclude coverage when other criteria are met unless the member contract specifically requires hormone therapy.

Penile prostheses and related devices: coverage guidance for penile prostheses and testicular prostheses follows medical necessity review; these may be covered for gender transition/affirmation when documentation supports medical necessity and device indications.

Imaging for facial surgery: CT imaging for facial feminization/masculinization is covered when clinically necessary to plan surgery and when documented in the medical record.

Hair removal distinctions: hair removal required for genital surgery preparation is medically necessary; non-genital hair removal for feminization/non-binary care may be covered per the policy branches; masculinization-targeted non-genital hair removal is not covered unless contract language states otherwise.

Transplants: uterine and penile transplants are investigational and not covered.

IHS site-of-service exception: the Site of Service medical necessity criteria within this policy do not apply to Indian Health Services (IHS) facilities; refer to the note in the policy header.

Must include diagnosis of gender dysphoria and recommendation/support for surgery
Prospective: evaluation or treatment within last 12 months
Retrospective: evaluation or treatment within 12 months immediately preceding surgery
Clinician must be a licensed mental health professional
2-year reuse exception applies only where explicitly allowed by policy

Documentation Required

Hair Removal — documentation & provider qualifications

Hair removal related to genital surgery requires documentation and must be performed or supervised by an approved provider in an appropriate clinic/office setting. When donor or genital sites are involved, documentation must specify the site(s) treated.

Approved provider types: licensed physicians, nurse practitioners, physician assistants, or other credentialed providers as specified by the plan
Hair removal must be provided in a clinic or office setting (not solely as an informal service)
Document donor and/or genital treatment sites when applicable

Documentation Required

Revision/Correction — required documentation

When a revision or correction to a prior gender transition/affirmation surgery is requested, documentation from the operating surgeon is required describing the clinical indication for the revision or correction and the planned procedure. If the original surgery was performed outside of the Plan or would not have been covered, documentation must demonstrate that the original surgery would have met coverage criteria.

Surgeon's documentation describing need for revision/correction and planned procedure
If original surgery was off-plan, provide evidence the original surgery met Plan coverage criteria

Billing Rule

Site of Service — select appropriate setting

Select the most appropriate, safe, and cost-effective site of service. Ambulatory surgical center (ASC) is the preferred site for many elective procedures when clinically appropriate. Inpatient hospital is medically necessary only when specified clinical risk factors are present (e.g., significant anesthesia or cardiac risk, prolonged surgery >3 hours, advanced comorbidities). Follow the policy's site-of-service criteria when planning care.

Preferred outpatient sites: Off-campus or on-campus outpatient hospital/medical center, Ambulatory Surgical Center (ASC)
Inpatient setting only when clinical risk factors increase complication risk (see policy list such as anesthesia risk, cardiovascular, pulmonary, liver, renal risks, morbid obesity, pregnancy, bleeding disorders, anticipated transfusion)
ASC may be appropriate for many elective gender-affirming surgeries when patient risk factors are absent

Denial Risk

Investigational procedures — denial risk

Uterine and penile transplantation are considered investigational. Claims for these procedures are subject to denial as investigational services under this policy.

Uterine transplantation — investigational
Penile transplantation — investigational
Claims for these services carry a high risk of denial

Documentation Required

Augmentation mammoplasty — hormone therapy not required

Augmentation mammoplasty (breast augmentation) is covered when criteria are met and hormone therapy is not a prerequisite for coverage. Document whether augmentation will be performed with implants or with autologous fat transfer.

Hormone therapy is not required for augmentation mammoplasty coverage
Document method: implant-based augmentation vs autologous fat transfer

Billing Rule

IHS exception — site of service review

The Site of Service Medical Necessity criteria in this policy does not apply to Indian Health Services (IHS) facilities—these facilities are exempt from the site's review requirements.

IHS facilities are excluded from site of service review requirements
Refer to policy for other documentation requirements

Documentation Required

Additional documentation & exception notes

Additional reminders and procedural notes to support documentation and billing: ensure mental health recommendation timing is within required 12-month window for prospective and retrospective requests; hair removal must be performed by approved providers in clinic/office settings and include treated site documentation; revisions for complications may have exceptions when addressing post-operative complications — document the complication, temporal relationship to original surgery, and the need for corrective procedure.

Mental health documentation must be current (within 12 months) for both prospective and retrospective reviews
Hair removal: provider qualification and clinic/office setting requirements must be met and documented
Revisions for complications: provide operative notes, complication description, and timeline to support coverage
