Medicare Health Maintenance Organizations (HMOs) are a type of Medicare Advantage plan.
Medicare HMOs are offered by private insurance companies that contract with Medicare to provide healthcare coverage to eligible beneficiaries.
Like other HMOs, Medicare HMOs have a network of hospitals, doctors, and other healthcare providers to which they refer patients.
Under a Medicare HMO, beneficiaries must receive healthcare services from providers within the HMO network, except in cases of emergency or urgent care. The HMO typically has a primary care physician (PCP) who coordinates the beneficiary's care and provides referrals to specialists within the network.
