What's The Difference Between HMO and PPO Plans?

It’s good to have choices. When it comes to health insurance, you have your choice of several plan types. Two you’ve probably heard of are a Health Maintenance Organization (HMO) and a Preferred Provider Organization (PPO). Generally speaking, the difference between HMO and PPO plans includes the size of the plan network, ability to see specialists, plan costs, and coverage for out-of-network services.

Let’s take a closer look at each plan type to see how they're alike, how they differ, and how you can choose the type of plan that meets your needs.

HMO Health Insurance Plans

An HMO gives you access to certain doctors and hospitals within its network. A network is made up of providers that have agreed to lower their rates for plan members and also meet quality standards. But unlike PPO plans, care under an HMO plan is covered only if you see a provider within that HMO’s network. There are few opportunities to see a non-network provider. There are also typically more restrictions for coverage than other plans, such as allowing only a certain number of visits, tests or treatments.

Some other key points about HMOs:

  • Some plans may require you to select a primary care physician (PCP), who will determine what treatment you need.
  • With some plans, you may need a PCP referral to be covered when you see a specialist or have a special test done.
  • If you opt to see a doctor outside of an HMO network, there is no coverage, meaning you will have to pay the entire cost of medical services.
  • Premiums are generally lower for HMO plans, and there is usually no deductible or a low one.

Some HMO plans, including those offered by Medical Mutual, don't require you to select a PCP or have a referral to see a specialist.

PPO Health Insurance Plans

PPO plans provide more flexibility when picking a doctor or hospital. They also feature a network of providers, but there are fewer restrictions on seeing non-network providers. In addition, your PPO insurance will pay if you see a non-network provider, although it may be at a lower rate.

Here are some key features:

  • You can see the doctor or specialist you’d like without having to see a PCP first.
  • You can see a doctor or go to a hospital outside the network and you may be covered. However, your benefits will be better if you stay in the PPO network.
  • Premiums tend to be higher, and it’s common for there to be a deductible.

HMO Versus PPO: Plan Comparison

HMOs tend to be more affordable, but you’ll usually get less coverage and more restrictions. PPOs are more flexible and provide greater coverage, but come with a higher price tag and probably a deductible. Here’s a summary of some of the key comparison points.

HMO PPO
Access to a network of doctors, hospitals and other healthcare providers
Ability to see the doctor you want without a PCP to authorize treatment
Referral from a PCP not needed to see a specialist
Low or no deductible and generally lower premiums
Coverage for medical expenses outside the plan’s network Possibly

Deciding Between an HMO and a PPO

If you have a choice between these two types of plans, consider your medical needs, availability of HMOs in your area and income. If you’re looking at an HMO, take a close look at the network to determine if the choices of doctors and medical facilities are enough to meet your needs. A PPO gives you more freedom, including the potential to be covered for medical bills outside the network, but your costs may be higher.
