Step-by-step explanation:
When someone becomes a member of an HMO, they must choose a primary care physician.
This statement is true. A health maintenance organization (HMO) is a type of health insurance plan that requires members to select a primary care physician (PCP). The PCP serves as the main point of contact for the member's medical care and is responsible for coordinating any necessary specialist care. By having a designated PCP, HMOs aim to provide coordinated and comprehensive healthcare services to their members.
