Variability in Medicaid Coverage for Gender-affirming Surgeries Across U.S. States.

[OBJECTIVE] To describe the current Medicaid coverage landscape for gender-affirming surgery across the United States at the procedure level and identify factors associated with coverage.

[BACKGROUND] Medicaid coverage for gender-affirming surgery differs by state, despite a federal ban on gender identity-based discrimination in health insurance. States that cover gender-affirming surgery also differ in which procedures are included in Medicaid coverage, leading to confusion among patients and clinicians.

[METHODS] State Medicaid policies in 2021 for gender-affirming surgery were queried for each of the 50 states and the District of Columbia (D.C.). State partisanship, state-level Medicaid protections, and coverage of gender-affirming procedures in 2021 were recorded. The linear correlation between electorate partisanship and total procedures covered was assessed. Pairwise t tests were used to compare coverage based on state partisanship and the presence or absence of state-level Medicaid protections.

[RESULTS] Medicaid coverage for gender-affirming surgery was covered in 30 states and Washington, D.C. The most commonly covered procedures were genital surgeries and mastectomy (n = 31), followed by breast augmentation (n = 21), facial feminization (n = 12), and voice modification surgery (n = 4). More procedures were covered in Democrat-controlled or leaning states, as well as in states with explicit protections for gender-affirming care in Medicaid coverage.

[CONCLUSIONS] Medicaid coverage for gender-affirming surgery is patchwork across the United States and is especially poor for facial and voice surgeries. Our study provides a convenient reference for patients and surgeons detailing which gender-affirming surgical procedures are covered by Medicaid within each state.
