Geographic Differences in Patient Demographics and Performance of Gender-Affirming Surgery From 2016 to 2019

Although legislation prohibiting gender identity discrimination in health insurance has shown some improvement in insurance coverage for gender-affirming surgery (GAS), recent bills criminalizing GAS providers in the South and Midwest regions pose threats to patient care.

To investigate the influence of US census region on patient demographics and GAS rates in the ambulatory surgery setting.

Individuals with gender dysphoria who underwent GAS in the ambulatory setting from 2016 to 2019 were identified in the Nationwide Ambulatory Surgery Sample (NASS) with billing codes. Demographic and clinical characteristics were analyzed and stratified by US census region.

The data set included a weighted estimate of 33,174 encounters with 72.8% (95% CI, 69.1-76.2) for chest reconstruction; 24.1% (95% CI, 20.9-27.5) for surgery on the genitals and reproductive organs; and 6.0% (95% CI, 4.6-7.8) for facial surgery. Overall, the rates of GAS increased by 187%, from 4320 encounters in 2016 to 12,396 encounters in 2019. In the Midwest, GAS increased by 257% compared to 203% in the Northeast, 218% in the South, and 154% in the West. Compared to patients in the West, those in other regions had higher odds of anxiety and depression (odds ratio, 1.57; 95% CI, 1.09-2.26; P < .05) and were more likely to have lower incomes than other ambulatory surgery patients in the region (P < .001).

Between 2016 and 2019, there was substantial growth of GAS in the Midwest, South, and Northeast. Regional differences in insurance coverage, socioeconomic status, availability of facial surgery, and comorbidities were observed.
