A lawmaker has filed a bill seeking to limit Florida's authority to operate a Medicaid privatization experiment even as state officials have begun to take a stand against the troubled pilot program. The proposal seeks to revoke the Agency for Health Care Administration's power to get money from the federal agency which helps fund the pilot program. Rep. Elaine Schwartz, D-Hollywood, filed the proposal and said her office is flooded with residents who can't get doctor's appointments and medicine.
