What are the 3 types of medical care plans?

The three main types of medical care plans are Health Maintenance Organizations (HMOs), Preferred Provider Organizations (PPOs), and Exclusive Provider Organizations (EPOs). HMOs require members to choose a primary care physician and obtain referrals for specialists, focusing on a network of providers. PPOs offer more flexibility in choosing healthcare providers and do not require referrals, although staying within the network reduces costs. EPOs combine elements of both, requiring members to use a network of providers but typically not needing referrals for specialists.
