What Does “Opting Out” Mean?

Opting out, or private contracting, is allowed under Section 4507 of the 1997 Balanced Budget Act.

This provision states that physicians can enter private contracts with Medicare beneficiaries, as long as specific conditions are met.

These conditions include the physician agreeing not to submit Medicare claims or receive payment for two years.

If you opt-out, neither Medicare nor Medicare Advantage plans will pay you or any entity to whom you might assign payment rights, except for emergency or urgent care services.

Before opting out

Before deciding to opt out of Medicare, carefully consider the following factors:

Financial impact

Assess the financial impact of opting out by reviewing patient mix, practice costs, and payment levels.

Expect a potential loss of Medicare patients if you choose private contracting.

While reducing overhead is a benefit, private contracting brings administrative tasks.

Consider the gain in fees against the percentage of lost Medicare patients for a balanced decision.

Prepare for a short-term revenue drop and ensure financial stability during the transition.

Contractual obligations

Your agreements with hospitals, health plans, or other entities, such as your employer, may mandate your participation as a Medicare physician.

Opting out of Medicare could potentially endanger or breach your contractual commitments and pose risks to various facets of your practice, such as credentialing.

It is advisable to thoroughly examine your contracts to ascertain whether Medicare participation is obligatory and, if so, understand the repercussions of choosing to opt-out.

Other considerations.

Several additional factors should be taken into account when determining whether opting out is the right choice.

Consider whether opting out aligns with your practice philosophy if it will enhance your job satisfaction, and how it might impact your practice’s reputation within the community—specifically, how non-Medicare patients and potential patients will respond.

Additionally, assess how opting out will influence your practice’s marketing strategy.

How To Opt Out

After choosing to withdraw from Medicare, you must proceed by completing the following actions:

1. Notify your patients, colleagues, and others.

Compose a letter to inform patients about your decision to opt-out, providing the reasons behind it and outlining options for their ongoing care.

Dispatch the communication well in advance, and extend a similar notification to relevant colleagues and entities with whom contractual ties exist.

Establish and document effective communication channels with patients before and after opting out to address potential misunderstandings or concerns.

2. Notify Medicare.

You must submit a written affidavit to each relevant Medicare contractor, signed by you and including your full name, address, and phone number, along with your NPI, billing number, or UPIN if applicable.

If you lack an NPI or UPIN, provide your tax identification number.

3. Privately contract with the Medicare patients you continue to care for.

Medicare beneficiaries choosing to receive non-urgent or non-emergency care from you are required to sign a private contract before undergoing treatment.

The contract must be composed in an easily readable, large typeface.

It is essential to retain a signed copy in your records and furnish the patient with their own signed copy.

4. Initiate appropriate office procedures

After executing affidavits and private contracts, establish office procedures to comply with opt-out rules.

Implement protocols to identify and notify Medicare patients of opt-out decisions, reminding them of payment arrangements.

In practices with both opting-out and non-opting-out doctors, develop procedures to identify each patient’s status and handle services accordingly.

Institute measures to avoid filing claims for services by opt-out physicians with private contracts with Medicare patients, using the emergency and urgent care exception cautiously.

5. Mark your calendar to renew your opt-out status.

The last task in this process is to schedule a regular reminder in your calendar.

Every two years, submit a new affidavit to ensure the continuation of your opt-out status.

Neglecting to renew your opt-out affidavit will result in engaging in private contracts with patients without Medicare approval.

These contracts will be considered invalid, and you will be required to submit claims retroactively for all the services provided.

If, after a two-year opt-out period, you decide to re-enroll in Medicare, follow the same procedure as a new participant.

Complete a new Medicare physician enrollment form to formalize your re-enrollment into the program.


If opting out of Medicare, follow proper procedures to maintain valid private contracts.

Failure to comply may void contracts.

You have a 90-day window post-opt-out to return without consequences.

Inform carriers and refund private contract funds.
