Introduction In the United States, 1.4–1.65 million people identify as transgender, many of whom will seek genital gender-affirming surgery (GAS). The number of surgeons, geographic proximity thereof, and exclusionary insurance policies has limited patient access to genital GAS. Aim To assess the accessibility of both feminizing and masculinizing genital GAS (vaginoplasty, metoidioplasty, and phalloplasty) by identifying the location of GAS surgeons, health insurance, or payment forms accepted. Methods Between February and April 2018, genital GAS surgeons were identified via Google search. Surgeons’ offices were contacted by telephone or e-mail. Main Outcome Measure We queried the type of genital GAS performed, the health insurance or payment forms accepted, and the type of medical practice (academic, private, or group managed-care practice). Results We identified 96 surgeons across 64 individual medical centers offering genital GAS. The survey response rate was 83.3%. Only 61 of 80 (76.3%) surgeons across 38 of 53 (72%) locations confirmed offering genital GAS. Only 20 (40%) U.S. states had at least one genital GAS provider. 30 of 38 (79%) locations reported accepting any form of insurance. Only 24 of 38 (63%) locations (14 academic; 10 private/group) accepted Medicaid ( P = .016); 18 of 38 (47%) locations (13 academic; 5 private/group) accepted Medicare ( P = .001). Clinical Translation Reconciliation of the public policies regarding insurance coverage for GAS with the actual practices of the providers is necessary for improving access to GAS for transgender individuals. Strengths & Limitations We purposefully used a methodology mirroring how a patient would find GAS surgeons, which also accounts for key limitations: only surgeons whose services were featured on the internet were identified. We could not verify the services or insurance-related information surgeons reported. Conclusion This study suggests that access to genital GAS is significantly limited by the number of providers and the uneven geographic distribution across the United States, in which only 20 of 50 U.S. states have at least one genital GAS surgeon.
