What is the difference between an HMO, EPO and PPO?

Buying a health plan that caters to both your expectations and budget can be a little tricky. Things get all the more difficult because of the industry jargon and terminology. So, you must be aware of certain acronyms, their benefits, and their shortcomings to make a better choice and go for a health plan that addresses your concerns aptly. This article aims to explain the meaning and differences between HMO, EPO, and PPO, enabling you to make an educated choice. 

Key Highlights

  • You should know the difference between EPO, HMO, and PPO plans in order to make a well-informed choice.
  • HMO plans are the cheapest. They require you to select a PCP, or Primary Care Physician.
  • PPO plans come with a greater degree of flexibility but can feel heavy on your pocket.

Epo, PPO and HMO explained

Let’s understand the three most common health plan types. 

HMO or Health Maintenance Organization, is one of the most affordable plans and operates within a relatively smaller network of healthcare providers. It requires you to opt for a Primary Care Physician (PCP). In case you require a specialist, the same PCP will refer you to one from within the HMO network. It serves as a prepaid health plan and covers healthcare services such as hospital stays, x-rays, lab tests, surgeries, etc. 

EPO stands for Exclusive Provider Organization. These health plans offer a fixed set of doctors, pharmacies, labs, and hospitals. But the network is comparatively larger than the HMO networks. Insurers have to choose services from within the EPO network when they want their expenses covered. However, there are certain special cases in EPO plans where an insurer can opt for out-of-network services without paying any additional costs.

PPO or Preferred Provider Organisations are more flexible than HMO plans. Insurers enjoy a higher degree of flexibility as compared to HMO or EPO plans. They can go with specialists or opt for out-of-network services without seeking the referral of a PCP. However, this flexibility can feel heavy on your pocket as the premiums of PPO plans tend to go quite high.

FAQs

The in-network coverage allows you to seek medical care within the HMO and EPO networks of healthcare providers and facilities. You pay less as the participating healthcare providers charge less, and your plans cover a major chunk of the expenses. On the other hand, the out-of-network coverage allows you to visit healthcare providers outside the network and charges a heavy premium for the same.
