If the Affordable Care Act is repealed, coverage of birth control with no co-payment is one of many benefits that Americans could lose. Now legislators in Oregon have introduced a bill intended to protect access to birth control in the state, along with a broad range of other reproductive health care services, including abortion.

The measure would require insurers in Oregon to cover all types of contraceptive drugs and devices approved by the Food and Drug Administration with no co-payment, co-insurance or deductible. It would extend the same requirement to a number of reproductive health services, including prenatal care, well-woman visits, screening for sexually transmitted infections, voluntary sterilization and abortion.

The bill also includes a provision that would prohibit insurers from discriminating against patients based on gender identity — for example, by refusing to cover gynecological exams for transgender women.

Under the Affordable Care Act, 30 million women gained co-pay-free access to preventive services like contraception, according to an estimate by the Department of Health and Human Services. An increase in the use of long-acting birth control methods has helped decrease the rates of unintended pregnancy and abortion nationwide.
