HMO Plans
HMO Plans, or Health Maintenance Organization Plans, include a network of providers, doctors, and hospitals. With HMOs, you may be required to choose a primary care physician, and receive a referral to see a specialist. Also, if you receive care outside of the network, you will not be covered.
These plans offer lower premiums compared to PPO Plans.
PPO Plans
PPO Plans, or Preferred Provider Organization Plans, also have a network of providers, doctors, and hospitals. However, unlike HMOs, PPOs do not always require you to receive care within the network. PPOs also do not require you to choose a primary care physician or receive referrals.
MSA Plans
MSA Plans, or Medicare Medical Savings Account Plans, include a high deductible plan and savings account that goes toward paying your medical costs. After you pay the high deductible, your coverage will begin. As for the savings account, the plan provider will deposit funds into the account each year. These funds can go towards paying on the deductible.
MSA Plans also have provider networks, but they also cover out-of-network care.
