Purpose: Transgender people face disparities in access to reproductive and sexual health services; however, differences in receipt of contraceptive services have not been quantified. We compare contraceptive patterns between cisgender women and trans masculine people in insurance claims databases. Methods: We analyzed 2014-2018 Truven MarketScan data, using diagnostic and procedural codes to identify sex assigned at birth, and existing coding methodology to identify transgender and nonbinary people. We compared contraceptive patterns between cisgender women and trans masculine people aged 15-49 in Medicaid and commercial databases. Results: We identified 4700 people in the commercial and 1628 people in the Medicaid databases as trans masculine. Trans masculine people were prescribed fewer oral contraceptive pills (Medicaid: 17.44%, commercial: 16.62%) compared to cisgender women (Medicaid: 24.96%, commercial: 27.85%), less long-acting reversible contraception (LARC) use (Medicaid: 7.62%, commercial: 7.49% vs. Medicaid: 12.79%, commercial: 8.51%), had more hysterectomies (Medicaid: 5.77%, commercial: 8.45% vs. Medicaid: 2.15%, commercial: 2.48%), and less evidence of any contraception (Medicaid: 34.21%, commercial: 32.28% vs. Medicaid: 46.80%, commercial: 39.81%). Hysterectomies and LARC use varied by insurance type. Conclusion: We found significant differences in contraceptive patterns between trans masculine people and cisgender women. Data suggest potential differences in hysterectomy occurrences by trans masculine people, and long-acting reversible contraceptive use by cisgender women, in Medicaid versus commercial insurance cohorts. Appropriate counseling, insurance coverage, and removal of structural barriers are needed to ensure adequate access to contraception methods for people of all genders-regardless of whether they are being employed for contraception, menstrual management, or gender affirmation.
