RICHMOND, Va. (AP) - A bill advancing in the General Assembly would require health insurance companies to cover a 12-month supply of prescription birth control.

A Senate committee approved the measure Monday. It has already passed the House of Delegates with only one no vote.

The bill's sponsor, Del. Eileen Filler-Corn, says it will ease a burden for women and prevent unwanted pregnancies and abortions. Three physicians testified in support of the measure.

The bill doesn't require that providers write a 12-month prescription.

Opponents, including insurance industry representatives, said the bill could lead to waste.
