Kaiser Permanente operates as a consortium comprising three distinct but interdependent entities: the Kaiser Foundation Health Plan (KFHP) and its regional subsidiaries, Kaiser Foundation Hospitals, and the regional Permanente Medical Groups. As of 2024, Kaiser Permanente serves eight states as well as the District of Columbia and is the largest managed care organization in the United States.
