What Is a HMO (Health Maintenance Organization)?
HMO plans require you to choose a primary care physician who coordinates your care. You need referrals to see specialists, and out-of-network care is generally not covered except in emergencies. HMOs typically have the lowest premiums of any plan type.
Best for: people who want lower premiums and are comfortable using a primary care physician for coordination and referrals.
Watch out for: HMOs can be restrictive if you have established specialist relationships or may need care outside your local area. Always confirm your specific doctors are in the HMO network before enrolling.
