In a California HMO plan, the member's Primary Care Physician (PCP) is responsible for making referrals and requesting authorizations on behalf of the member.
An HMO, or Health Maintenance Organization, is a type of health insurance plan where a primary care physician serves as the main point of contact for all healthcare needs.
