To be eligible to join an HMO, you must live in that HMO's service area. HMO membership may not be available throughout an entire county; precise service areas are specified by home ZIP code. Because of the ongoing nature of HMO service territory changes, we recommend that you verify the service area and provider availability with each HMO.

See the Health Care Participation section for general information on eligibility for medical coverage, including coverage under an HMO.
