OK SB176

Defines "contraceptive drugs" as all FDA-approved drugs used to prevent pregnancy, including hormonal drugs administered orally, transdermally, and intravaginally.

Requires health benefit plans offering contraceptive drug coverage to provide a three-month supply on the first fill and a six-month supply on all subsequent fills of the same drug.

Limits enrollees to obtaining only one six-month supply of a covered prescription drug during each six-month period.

Permits enrollees and prescribing providers to request or prescribe smaller supplies if supported by clinical utility and medical appropriateness.

Explicitly excludes medications that could be used to terminate an existing pregnancy from coverage requirements and becomes effective November 1, 2025.
