Medicare assignment is a term used to describe how a healthcare provider agrees to accept the Medicare-approved amount. Depending on how you get your Medicare coverage, it could be essential to understand what it means and how it can affect you.

What is Medicare assignment?

Medicare sets a fixed cost to pay for every benefit they cover. This amount is called Medicare assignment.

You have the largest healthcare provider network with over 800,000 providers nationwide on Original Medicare. You can see any doctor nationwide that accepts Medicare.

Understanding the differences between your cost and the difference between accepting Medicare and accepting Medicare assignment could be worth thousands of dollars.

Doctors that accept Medicare

Your healthcare provider can fall into one of three categories:

  1. Medicare participating provider and Medicare assignment
  2. Medicare participating providers not accepting Medicare assignment
  3. Medicare non-participating provider

More than 97% of healthcare providers nationwide accept Medicare. Because of this, you can see almost any provider throughout the United States without needing referrals.

Let’s discuss the three categories the healthcare providers fall into.

Medicare participating provider and Medicare assignment

Participating providers are doctors or healthcare providers who accept assignment. This means they will never charge more than the Medicare-approved amount.

Medicare participating providers not accepting Medicare assignment

Some non-participating providers accept Medicare but not Medicare assignment. This means you can see them the same way a provider accepts assignment.

You need to understand that since they don’t take the assigned amount, they can charge up to 15% more than the Medicare-approved amount.

Since Medicare will only pay the Medicare-approved amount, you’ll be responsible for these charges. The 15% overcharge is called an excess charge. A few states don’t allow or limit the amount or services of the excess charges. Only about 5% of providers charge excess charges.

Medicare non-participating provider

Opt-out providers don’t accept Original Medicare, and these healthcare providers are in the minority in the United States. If healthcare providers don’t accept Medicare, they won’t be paid by Medicare.

This means choosing to see a provider that doesn’t accept Medicare will leave you responsible for 100% of what they charge you. These providers may be in-network for a Medicare Advantage plan in some cases.

Avoiding excess charges

Excess charges could be large or small depending on the service and the Medicare-approved amount. Avoiding these is easy. The simplest way is to ask your provider if they accept assignment before service.

If they say yes, they don’t issue excess charges. Or, on Medicare.gov, a provider search tool will allow you to look up your healthcare provider and show if they accept Medicare assignment or not.

Medicare Supplement and Medicare assignment

Medigap plans are additional insurance that helps cover your Medicare cost-share. If you are on specific plans, they’ll pay any extra costs from healthcare providers that accept Medicare but not Medicare assigned amount. Most Medicare Supplement plans don’t cover the excess charges.

The top three Medicare Supplement plans cover excess charges if you use a provider that accepts Medicare but not Medicare assignment.

Medicare Advantage and Medicare assignment

Medicare assignment does not affect Medicare Advantage plans since Medicare Advantage is just another way to receive your Medicare benefits. Since your Medicare Advantage plan handles your healthcare benefits, they set the terms.

Most Medicare Advantage plans require you to use network providers. If you go out of the network, you may pay more. If you’re on an HMO, you’d be responsible for the entire charge of the provider not being in the network.
