Geographic Variability of Genital Gender-Affirming Surgery Centers and Costs of Hospitalization.

Abstract

The cost of gender-affirming surgery (GAS) is an important component of healthcare accessibility for transgender patients. However, GAS is often prohibitively expensive, particularly as there are inconsistencies in insurance coverages. Variability in hospital costs has been documented for other types of nonplastic surgery procedures; however, this analysis has not been done for GAS. To better understand the financial barriers impairing access to equitable transgender care, this study analyzes the distribution of hospitals that perform genital GAS and the associated costs of inpatient genital GAS. This is a study of the 2016-2019 National Inpatient Sample database. Transgender patients undergoing genital GAS were identified using International Classification of Diseases, Tenth Revision, diagnosis and procedure codes, and patients undergoing concurrent chest wall GAS were excluded. Descriptive statistics were done on patient sociodemographic variables, hospital characteristics, and hospitalization costs. χ2 test was used to assess for differences between categorical variables and Mood's median test was used to assess for differences between continuous variable medians. A total of 3590 weighted genital GAS encounters were identified. The Western region (50.8%) and Northeast (32.3%) performed the greatest proportion of GAS, compared with the Midwest (9.1%) and the South (8.0%) (P < 0.0001). The most common payment source was private insurance (62.8%), followed by public insurance (27.3%). There were significant differences in the variability of median hospital costs across regions (P < 0.0001). The South and Midwest had the greatest median cost for vaginoplasty ($19,935; interquartile range [IQR], $16,162-$23,561; P = 0.0009), while the West had the greatest median cost for phalloplasty ($26,799; IQR, $19,667-$30,826; P = 0.0152). Across both procedures, the Northeast had the lowest median cost ($11,421; IQR, $9155-$13,165 and $10,055; IQR, $9,013-$10,377, respectively). There is significant regional variability in the number of GAS procedures performed and their associated hospitalization costs. The identified disparities in insurance coverage present an area of possible future improvement to alleviate the financial burden GAS presents to gender-discordant individuals. The variability in cost suggests a need to evaluate variations in care, leading to cost standardization.
