If your doctor is part of the plan network, you'll be able to keep visiting them for services. However, if they are outside of the network, you will either need to enroll in an HMO-POS plan or choose a different PCP to avoid paying out-of-pocket costs.
A PCP is a family medicine doctor, nurse practitioner, physician assistant, internist, pediatrician, or geriatrician. PCPs treat a wide range of health issues and can help coordinate your medical treatment with various specialists.
