HMO vs EPO – Quick Answer

Here’s the short version:

HMO: You need a primary care doctor and referrals to see specialists.
EPO: You can see any specialist in-network without a referral, but there’s no coverage for out-of-network care.

Examples:

HMO Example: You have a cough. You visit Dr. Smith (your primary doctor), who then refers you to a lung specialist.
EPO Example: You feel chest pain and directly book an appointment with a cardiologist in your network.
Cost Example: HMO plans usually have lower premiums, while EPOs might be slightly more expensive but save time on referrals.

The Origin of HMO vs EPO

The terms HMO and EPO come from the United States.

HMO started in the 1970s to help people get preventive care and control costs.
EPO came later, giving people more flexibility than HMOs but still keeping care inside a network.
