Amedisys provides home-based healthcare services across three lines: home health, hospice, and high acuity care. Home health — the largest segment — delivers skilled nursing, physical therapy, occupational therapy, speech therapy, and social work services to homebound patients recovering from surgery, managing chronic conditions, or avoiding hospital readmissions. Hospice provides end-of-life comfort care for terminally ill patients. High acuity care, the newest and smallest segment launched via the 2021 acquisition of Contessa Health, delivers hospital-level and SNF-level care at home through joint ventures with health system partners. Amedisys operates 519 care centers across 38 states, serving over 499,000 patients annually. Revenue is driven by clinical visits and care episodes, with roughly 70–74% of net service revenue coming from Medicare. Home health reimbursement operates under CMS's per-episode payment model, while hospice is reimbursed on a daily rate. High acuity care runs on risk-based contracts, where Amedisys receives a fixed episode payment and bears the cost of care — carrying more financial risk than the other two segments. Labor is the primary cost across all segments, so clinician utilization and visit efficiency are key margin drivers. In June 2023, UnitedHealth Group agreed to acquire Amedisys, which would fold the company into UnitedHealth's Optum division alongside its existing home health and hospice businesses.
