If you are planning on enrolling in Medicare, you might be considering either original Medicare with add-ons or a comprehensive Medicare Advantage plan. There are a handful of different types of Medicare Advantage plans, but the most popular are the Medicare Advantage HMO plans. If you enroll in a Medicare Advantage HMO, your care will be provided by in-network providers.

Let’s look at what Medicare Advantage HMO plans offer, how to enroll, and some of the advantages and disadvantages of choosing a Medicare Advantage HMO plan over original Medicare.

Medicare Advantage is a type of Medicare coverage that is offered by private insurance companies. With Medicare Advantage plans, you are covered for Medicare Part A, Medicare Part B, and some additional health coverage options, such as prescription drugs, dental, vision, and more. Medicare Advantage plans can have different plan structures, such as HMOs, PPOs, SNPs, and more.

Medicare Advantage HMOs, or Health Maintenance Organization plans, are based around in-network medical care. This means that you are given a list of in-network providers to choose from when you need medical services. If you decide to select a provider who is out of network, you may owe a higher cost or the full out-of-pocket amount for those services.

All Medicare Advantage HMO plans must cover at least:

  • hospital insurance (Medicare Part A), including skilled nursing and home health care, as well as hospice care
  • medical insurance (Medicare Part B), including preventative and diagnostic healthcare

Most Medicare Advantage HMO plans also include:

To enroll in a Medicare Advantage HMO plan, you must already be enrolled in Medicare parts A and B. Once this is done, you are eligible to enroll in a Medicare Advantage HMO plan in your state.

So, how exactly do Medicare Advantage HMOs work? What happens if you need out-of-network emergency medical care? Do specialist visits require a referral?

Here are some commonly asked questions about Medicare Advantage HMOs.

How do Medicare Advantage HMOs work?

Medicare Advantage HMO plans rely on services from in-network healthcare providers, hospitals, and other providers. If you choose to use services from out-of-network providers, you might be charged more or the full cost of those services.

An exception to this rule is if you need emergency care or are traveling and require urgent care or a dialysis visit. When you enroll in your plan, you will be provided a list of in-network providers and specific rules regarding out-of-network care.

There are some types of Medicare Advantage HMO plans that allow you to seek services from out-of-network providers. These point of service (POS) plans usually have different rules than regular HMO plans.

Can I keep my doctor?

If your doctor is part of the plan network, you will be able to keep visiting them for services. However, if they are outside of the network, you will either need to enroll in an HMO-POS plan or choose a different primary care physician (PCP) to avoid paying out-of-pocket costs.

A PCP is a family medicine doctor, nurse practitioner, physician assistant, internist, pediatrician, or geriatrician. PCPs treat a wide range of health issues and can help coordinate your medical treatment with various specialists.

Do I need a referral to see a specialist?

With a Medicare Advantage HMO plan, most specialist visits require a referral from your PCP. However, certain preventative visits, such as screening mammograms, do not require specialist referral.

Do they cover prescription drugs?

Each Medicare Advantage HMO plan stipulates what type of coverage it offers in addition to Medicare parts A and B. However, most Medicare Advantage HMO plans cover prescription drugs. If you require prescription drug coverage, make sure it’s included in the plan you select.

Do I have to go to a medical center for my services or prescription drugs?

With a Medicare Advantage HMO, you can visit any office, medical center, or pharmacy that is accepted in your plan’s network.

How do Medicare Advantage HMOs compare to original Medicare?
