Temporal trends in gender-affirming surgery among transgender patients in the United States

IMPORTANCE Little is known about the incidence of gender-affirming surgical procedures for transgender patients in the United States. OBJECTIVES To investigate the incidence and trends over time of gender-affirming surgical procedures and to analyze characteristics and payer status of transgender patients seeking these operations. DESIGN, SETTING, AND PARTICIPANTS In this descriptive observational study from 2000 to 2014, data were analyzed from the National Inpatient Sample, a representative pool of inpatient visits across the United States. The initial analyses were done from June to August 2015. Patients of interest were identified by International Classification of Diseases, Ninth Revision, diagnosis codes for transsexualism or gender identity disorder. Subanalysis focused on patients with procedure codes for surgery related to gender affirmation. MAIN OUTCOMES AND MEASURES Demographics, health insurance plan, and type of surgery for patients who sought gender-affirming surgery were compared between 2000-2005 and 2006-2011, as well as annually from 2012 to 2014. RESULTS This study included 37 827 encounters (median [interquartile range] patient age, 38 [26-49] years) identified by a diagnosis code of transsexualism or gender identity disorder. Of all encounters, 4118 (10.9%) involved gender-affirming surgery. The incidence of genital surgery increased over time: in 2000-2005, 72.0% of patients who underwent gender-affirming procedures had genital surgery; in 2006-2011, 83.9% of patients who underwent gender-affirming procedures had genital surgery. Most patients (2319 of 4118 [56.3%]) undergoing these procedures were not covered by any health insurance plan. The number of patients seeking these procedures who were covered by Medicare or Medicaid increased by 3-fold in 2014 (to 70) compared with 2012-2013 (from 25). No patients who underwent inpatient gender-affirming surgery died in the hospital. CONCLUSIONS AND RELEVANCE Most transgender patients in this national sample undergoing inpatient gender-affirming surgery were classified as self-pay; however, an increasing number of transgender patients are being covered by private insurance, Medicare, or Medicaid. As coverage for these procedures increases, likely so will demand for qualified surgeons to perform them.
