Insurance: health insurers; coverage for the dispensing of a 12-month supply of birth control; require. Amends 1956 PA 218 (MCL 500.100 - 500.8302) by adding sec. 3406jj.

HB 4496 amends Michigan's insurance code to require health insurance policies to cover a 12-month supply of prescription contraceptives. It mandates that insurers provide coverage for these contraceptives, which are on the health plan's formulary, to be dispensed all at once unless otherwise requested or instructed by a prescriber. The bill also requires coverage for necessary outpatient services related to prescribing or dispensing contraceptives, if other prescription drugs are covered by the policy. While standard cost-sharing like copayments and deductibles can apply, insurers are prohibited from imposing utilization controls that limit the supply to less than 12 months. This measure applies to health insurance policies beginning December 31, 2025.
