MONTGOMERY, Ala. (AP) -- Alabama's top health officer says state Medicaid is facing a major funding shortfall.

The director of the Alabama Department of Public Health, Dr. Don Williamson, says federal changes will add $30 million to the state's Medicaid funding needs for 2014.

Reports suggest that state officials didn't know about the additional cost when voters approved using $437 million from a state fund to plug the Medicaid budget in September.

Williamson says the state is looking at the additional money just to keep the program where it is without fundamental changes in the program.

Williamson has said Alabama Medicaid will likely switch to a managed-care system to save money.
