Topeka ? A new proposal for controlling the cost of mental health drugs to the Medicaid program in Kansas has advanced in the Legislature.

The Senate gave first-round approval Monday to a bill requiring a review of Medicaid’s mental health prescriptions. It also creates an advisory committee to draft guidelines on prescriptions for the needy and disabled covered by the program.

Senators expected to take final action Tuesday.

The measure had bipartisan support and arose from discussions between Republican Gov. Sam Brownback’s administration and mental health advocates.

The Senate last month rejected a bill repealing a 2002 law that blocks restrictions on mental health drugs for Medicaid participants.

Supporters of such efforts are looking for cost savings to help balance the state budget. They also worry some drugs are used improperly.
