Bill No. 1683 mandates that health benefit plans in Oklahoma, effective November 1, 2025, must provide coverage for contraceptive drugs as defined by the bill. Specifically, the legislation requires that any health benefit plan offering coverage for these drugs must allow enrollees to obtain a three-month supply of a contraceptive drug at once upon their initial prescription and a twelve-month supply at once for subsequent prescriptions, regardless of prior enrollment status. However, enrollees are limited to one twelve-month supply of a covered prescription drug within a twelve-month period.

The bill also clarifies that enrollees can request smaller supplies of contraceptive drugs, and prescribing providers can prescribe smaller amounts if deemed clinically appropriate. Importantly, the legislation does not require coverage for contraceptive drugs that are not intended for regular or routine use. This new section will be codified as Section 6060.3b of Title 36 in the Oklahoma Statutes.
