The Closing the Contraception Coverage Gap Act would require Medicare to cover all contraceptive items and services with no cost-sharing starting January 1, 2026. This includes contraceptive drugs, devices, and related clinical services such as consultations, examinations, device insertion, and counseling, based on guidance established by the Public Health Service Act. The coverage applies to Medicare Part B, Part C (Medicare Advantage), and Part D (prescription drug plans), meaning beneficiaries would not pay deductibles, copayments, or coinsurance for these services. The bill also directs the Department of Health and Human Services to study prescription drug coverage gaps for Medicare beneficiaries with disabilities and requires government accountability offices to study contraceptive coverage requirements across commercial and public health insurance plans. The legislation aims to eliminate existing gaps in contraceptive coverage that currently affect Medicare recipients.
