With an HMO, you must choose a primary care physician (PCP) from a network of local healthcare providers when you join. This is the doctor you will see whenever you need medical care. Your PCP will be the provider with the best overall picture of your health and will be the one to coordinate any additional care you might need.
If you were to need the care of a specialist, you would first see your PCP. Then, if needed, he or she would provide a referral to a specialist within the HMO’s network.
For example, if you suffer from back pain you would first be examined by your PCP. If your doctor determined you needed the services of a specialist, he or she would refer you to an in-network specialist for care. Since the specialist is in your network, those services would be covered by your insurance after making any copays or coinsurance and meeting your deductible.
If you’d like to keep your current doctor and he or she does not belong to an HMO network, you might want to consider a preferred provider organization (PPO) plan instead.
