Legislations Mandating Insurance Coverage Are Highly Effective in Delivering Surgical Care of Transgender Patients

Although gender-affirming surgery is increasingly performed, few studies have examined any temporal correlation between legislations mandating transgender care and the actuation of such surgical care.

We assembled a retrospective cohort utilizing the National Inpatient Sample database from 2000 to 2018. We stratified utility trends of gender-affirming surgery based on insurance payer types and regions in a crisscrossing effort to detect any temporal or cause-effect relationship between legislations and outcomes. All regions according to the latest National Inpatient Sample categorization were examined based on the nature of their member state's legislations relating to gender-affirming care coverage. Diametrically, opposite regions were selected for further comparisons. Interrupted time series analyses were used to demonstrate any significant uptrend since implementation of relevant legislations.

In states with explicit inclusion of gender-affirming care, our interrupted time series analyses showed a significant increase in the number of patients on state-dependent insurance (Medicaid and private insurance) receiving gender-affirming surgery around the time during which state legislations began mandating care (P < 0.01) and thereafter (P < 0.01). This significance was not seen in the same regions among patients under nonstate-dependent payers (Medicare and self-pay), nor was it seen in either payer group in states without explicit inclusion of gender-affirming care. At the federal level, statistical significance was noted among Medicare recipients across all states around the time federal legislations took effect and thereafter.

Legislations mandating coverage seem highly effective in actuating surgical care of transgender patients in corresponding jurisdictions, which may provide a roadmap for further care expansion.
