American Eldercare Inc., the only statewide winner of Florida Medicaid long-term-care managed-care contracts, is about to become part of Humana, the latter company said in a news release. This will propel Humana into the role of major player in the rollout of the new state program for elderly Medicaid recipients, which begins Aug. 1. American Eldercare, which is privately held, specializes in keeping residents of assisted-living facilities (ALFs) stable and out of nursing homes.
