A Medicare non-participating provider decides whether to accept assignment on a basis

You can get the lowest cost if your doctor or other health care provider accepts the Medicare-approved amount  as full payment for a covered service. This is called “accepting assignment.” If a provider accepts assignment, it’s for all Medicare-covered Part A and Part B services.

Using a provider that accepts assignment

Most doctors, providers, and suppliers accept assignment, but always check to make sure that yours do.

If your doctor, provider, or supplier accepts assignment:

  • Your out-of-pocket costs may be less.
  • They agree to charge you only the Medicare deductible and coinsurance amount, and usually wait for Medicare to pay its share before asking you to pay your share.
  • They have to submit your claim directly to Medicare and can't charge you for submitting the claim.

Using a provider that doesn't accept Medicare as full payment

Some providers who don’t accept assignment still choose to accept the Medicare-approved amount for services on a case-by-case basis. These providers are called "non-participating."

If your doctor, provider, or supplier doesn't accept assignment:

  • You might have to pay the full amount at the time of service.
  • They should submit a claim to Medicare for any Medicare-covered services they give you, and they can’t charge you for submitting a claim. If they refuse to submit a Medicare claim, you can submit your own claim to Medicare. Get the Medicare claim form.
  • They can charge up to 15% over the Medicare-approved amount for a service, but no more than that. This is called "the limiting charge."  

Does the limiting charge apply to all Medicare-covered services?

Using a provider that "opts-out" of Medicare

  • Doctors and other providers who don’t want to work with the Medicare program may "opt out" of Medicare.
  • Medicare won’t pay for items or services you get from provider that opts out, except in emergencies.
  • Providers opt out for a minimum of 2 years. Every 2 years, the provider can choose to keep their opt-out status, accept Medicare-approved amounts on a case-by-case basis ("non-participating"), or accept assignment.

Find providers that opted out of Medicare.

Private contracts with doctors or providers who opt out

  • If you choose to get services from an opt-out doctor or provider you may need to pay upfront, or set up a payment plan with the provider through a private contract.
  • Medicare won’t pay for any service you get from this doctor, even if it’s a Medicare-covered service.

Question What is the difference between participating and non-participating providers for Medicare? What are the options for audiologists in being able to participate in either manner?

Answer Editor's note: Effective 9-9-09, the information in this Ask the Expert has been updated, specifically with regard to audiologists "opting-out" of participation with Medicare. Please refer to the new, updated Ask the Expert here: /askexpert/display_question.asp?question_id=654Every audiologist must decide if they should participate or not with Medicare, as well as, other third party payors. Most seniors and people in general do look for providers who accept their insurance, so choosing not to participate can have devastating negative affects on a healthcare business. That said, randomly participating with all third party payors without understanding the terms of that participation including reimbursement levels and potential risks can also be devastating to an audiology business.With Medicare, audiologists basically have three choices;participate as a "participating provider", participate as a "non-participating provider", or "opt-out". One's chosen status with Medicare will dictate who you bill, how much you collect for a given procedure, the responsible party, whether or not you must have a "private contract" with beneficiaries, and what that private contract must include to name a few things.Although Medicare is a federally funded program, it is also administered by state or regional intermediaries who have been know to interpret Medicare (federal) policy differently. It is always wise to identify, contact, and document in writing any information that is provided to you by your intermediary.As a general rule: (adsbygoogle = window.adsbygoogle || []).push({}); "Participating Providers" accept assignment from Medicare. The provider bills Medicare at their usual and customary fee;however, Medicare pays the provider 80% of the "allowed amount" for each CPT code. Patients are responsible for 20% of the allowed amount and this 20% should not be waived. The provider cannot bill patients for amounts in excess of the allowed amount and must write off the difference between the allowed amount and usual and customary fees."Non-participating Providers" do in fact participate with Medicare. Non-par providers generally do not accept assignment on a regular basis;however, can choose to accept assignment on a case-by-case basis and be reimbursed at the non-par level. Non-par providers must bill Medicare, but Medicare reimburses the patient versus the provider. The amount patients receive from Medicare will be 5% less than the par-allowed amount and the patient pays the provider for services rendered.A non-par provider can legitimately increase reimbursement by charging the "limiting fees", which represent the maximum allowable reimbursement. Limiting fees, as well as, par and non-par allowed fees can vary by region, state, and even city and can be found at www.cms.gov."Opting-Out" (Editor's note - effective 9-9-09, this information is no longer up to date. Please refer to the latest information here: /askexpert/display_question.asp?question_id=654). If an audiologist sees Medicare beneficiaries and chooses not to participate with Medicare, they must opt-out and in many states sign an opt-out affidavit. That opt-out affidavit also includes private contract requirements. If you choose to opt-out, you cannot re-apply for Medicare participation status for two years. It is very important to understand the impact third party payor participation can have on one's practice before committing to any level of provider status or choosing to opt-out.Note: "Audiologists" are not specifically listed under physicians or practitioners who are eligible to contract privately;however, audiologists do meet the criteria of being "legally authorized to practice by the state and otherwise meet Medicare requirements". Various Medicare intermediaries can interpret this differently.Kathy Foltner, AuD, is CEO of AuDNet, Inc.

What does non

A non-participating provider has agreed to accept Medicare insurance but not accept assignment. Consequently, non-participating providers may charge up to 15% above the Medicare approved amount for the Medicare-covered service. This extra payment is called the limiting charge.

What does it mean when a provider does not accept assignment?

These providers are called "non-participating." If your doctor, provider, or supplier doesn't accept assignment: You might have to pay the full amount at the time of service. They should submit a claim to Medicare for any Medicare-covered services they give you, and they can't charge you for submitting a claim.

What does it mean when a provider accepts assignment?

Assignment means that your doctor, provider, or supplier agrees (or is required by law) to accept the Medicare-approved amount as full payment for covered services. This means that for Medicare to cover the entire cost of a covered service, you'll need to go to a service provider who accepts assignment.

What is the difference between a participating and non

Participating provider versus non-participating Provider - Reimbursement is 5 percent higher than the non-participating amount. - Medigap information is transferred. - A non-participating provider has not entered into an agreement to accept assignment on all Medicare claims.
