Select Tier 1 (HMO) benefit level offers comprehensive care at a lower cost to the member who uses Health Net's participating providers for care. Select Tier 1 is similar to a traditional HMO plan. The member chooses a primary care physician (PCP) who is responsible for providing or coordinating the member's care. If the member requires services outside the PCP's scope of practice, the PCP refers the member to a specialist or other ancillary provider.
