Medicare Opt-Out Form PDF: A Comprehensive Guide (Updated 12/17/2025)
Navigating the Medicare opt-out process requires a completed affidavit form, readily available from the Centers for Medicare & Medicaid Services (CMS).
This detailed guide, updated today – December 17, 2025 – provides essential information regarding the form, its completion, and associated requirements for practitioners seeking to opt-out.
What is the Medicare Opt-Out Option?
The Medicare opt-out option, established under Section 1802 of the Social Security Act, allows eligible healthcare providers to voluntarily withdraw from participation in the Medicare program. This means they choose not to submit claims to Medicare for their services. However, opting out isn’t a simple decision; it necessitates adhering to specific regulations and fulfilling certain obligations.
Since January 1, 1998, physicians and practitioners have had the right to opt-out, enabling them to establish private contractual agreements directly with Medicare beneficiaries. These contracts allow providers to set their own fees, potentially exceeding Medicare’s established limits. However, a crucial element is the mandatory two-year opt-out period, automatically renewed unless a provider actively re-enters the Medicare program. Successfully opting out requires submitting a valid Opt Out Affidavit to Medicare.
Eligibility Requirements for Opting Out

To be eligible to opt-out of Medicare, a provider must be a physician or practitioner as defined by Medicare regulations. This generally includes doctors, dentists, podiatrists, psychologists, and other healthcare professionals authorized to provide services under Medicare. Importantly, groups or organizations cannot opt-out; only individual practitioners are eligible.
Before submitting the Opt Out Affidavit, practitioners must ensure they intend to serve all Medicare beneficiaries on a private contract basis. They cannot selectively opt-out for certain patients. Furthermore, providers must not have any outstanding Medicare claims or debts. A clean billing record is essential. The decision to opt-out is a significant one, requiring careful consideration of its implications and adherence to all CMS guidelines.
Understanding Section 1802 of the Social Security Act
Section 1802 of the Social Security Act is the foundational legal basis for the Medicare opt-out provision. Enacted in 1998, it permits physicians and practitioners to voluntarily withdraw from Medicare participation. This allows them to establish private contractual arrangements directly with Medicare beneficiaries, bypassing Medicare’s fee schedule and claim submission processes.
However, this freedom comes with strict stipulations. Section 1802 mandates a two-year opt-out period and requires a valid Opt Out Affidavit be filed with Medicare. It also outlines the necessity of a written private contract with each beneficiary, detailing agreed-upon charges. Understanding this section is crucial, as non-compliance can lead to penalties and re-entry restrictions into the Medicare program.
Why Would a Provider Opt-Out of Medicare?
Providers choose to opt-out of Medicare for various reasons, primarily centered around financial and practice autonomy. Many seek to establish direct patient relationships, setting their own fees outside of Medicare’s statutory charge limits. This is particularly appealing for specialists offering services where Medicare reimbursement rates are perceived as inadequate.
Opting-out allows practitioners to offer potentially more comprehensive or specialized care without the constraints of Medicare guidelines. However, this requires diligent adherence to the Opt Out Affidavit requirements and the establishment of private contracts with each beneficiary. It’s a strategic decision balancing increased financial control with the responsibility of direct billing and patient communication regarding costs.
The Two-Year Mandatory Opt-Out Period
Upon submitting a valid Opt Out Affidavit to Medicare, providers commit to a mandatory two-year opt-out period. This isn’t a temporary arrangement; once the affidavit is processed, the practitioner cannot bill Medicare for any services rendered to beneficiaries during these 24 months. This commitment is legally binding and crucial for maintaining compliance.

The two-year timeframe begins from the date Medicare officially acknowledges receipt of the completed Opt Out Affidavit. Furthermore, this opt-out election is automatically renewed for another two-year period unless the provider actively submits a new affidavit to re-enter the Medicare program. Careful planning is essential, as prematurely billing Medicare during this period can result in significant penalties.
Automatic Renewal of Opt-Out Election
The Medicare opt-out isn’t a one-time decision; it features automatic renewal unless proactively addressed. Following the initial two-year mandatory period established by the Opt Out Affidavit, the election to remain outside the Medicare system continues indefinitely, renewing automatically every two years. This means practitioners don’t need to resubmit the affidavit to maintain their non-participating status.
However, if a provider wishes to re-enter the Medicare program before the automatic renewal, they must submit a new affidavit specifically requesting reinstatement. Failing to do so will result in continued exclusion from Medicare billing. Understanding this automatic renewal is vital for avoiding unintended consequences and ensuring compliance with Medicare regulations regarding the Opt Out Affidavit process.

The Opt-Out Affidavit Form
The cornerstone of opting out of Medicare is the official affidavit form (CMS Form), a legally binding document. Accurate completion and submission are crucial for a valid election.
Obtaining the Medicare Opt-Out Affidavit Form (CMS Form)
Accessing the necessary Medicare Opt-Out Affidavit Form (CMS Form) is a straightforward process, primarily facilitated through the Centers for Medicare & Medicaid Services (CMS) resources. Practitioners can directly download the current version of the form as a PDF document from the official CMS website. This ensures you are utilizing the most up-to-date iteration, crucial for compliance.
Alternatively, you may request a physical copy of the form through the CMS Expert Help Desk. While digital access is generally faster, a mailed copy is available for those preferring a tangible document. It’s important to verify the form’s validity upon receipt, confirming it aligns with the current year’s requirements. Ensure the downloaded or received form is complete and legible before beginning the completion process, as incomplete or illegible forms may cause delays or rejection.
CMS Expert Help Desk Contact Information
For direct assistance regarding the Medicare Opt-Out Affidavit form and the opt-out process, the CMS Expert Help Desk serves as a valuable resource. While specific contact details may evolve, generally, practitioners can reach the help desk via email. As of recent information, a primary email address for inquiries is protected, ensuring secure communication regarding sensitive information.
It’s important to note that response times may vary depending on the volume of inquiries. The CMS website also provides a comprehensive FAQ section addressing common questions about opting out; Additionally, the U.S. government’s official website offers further resources and guidance. When contacting the help desk, clearly articulate your specific question or concern to facilitate a prompt and accurate response. Keep a record of all communication, including dates and reference numbers, for future reference.
Key Components of the Opt-Out Affidavit
The Medicare Opt-Out Affidavit (CMS Form) is a legally binding document with several crucial components. It begins with identifying information for the practitioner, including name, address, and Taxpayer Identification Number (TIN). A clear statement of intent to opt-out of all Medicare programs is central, specifying the effective date of this election.
The affidavit requires a detailed acknowledgement of the practitioner’s responsibilities, including direct billing to beneficiaries and adherence to statutory charge limits. A section dedicated to attestation confirms the accuracy of the provided information and understanding of the two-year mandatory opt-out period. Finally, the form necessitates a signature and date, solidifying the practitioner’s commitment. Careful review of each section is paramount before submission.
Information Required on the Affidavit

Completing the Medicare Opt-Out Affidavit (CMS Form) demands precise and comprehensive information. Practitioners must provide their full legal name, practice address, and unique Taxpayer Identification Number (TIN). Detailed contact information, including phone number and email, is also essential for CMS communication.
The affidavit requires specifying the exact date the opt-out election will become effective. Practitioners must clearly indicate their understanding of the two-year commitment and automatic renewal. Furthermore, information regarding any previous Medicare participation, including enrollment dates, may be requested. Accurate attestation regarding private contracting with beneficiaries is critical. Any omissions or inaccuracies can lead to processing delays or rejection of the affidavit.
Completing the Affidavit Accurately
Meticulous attention to detail is paramount when completing the Medicare Opt-Out Affidavit. Ensure all information provided aligns precisely with official records, including your Taxpayer Identification Number (TIN) and National Provider Identifier (NPI). Double-check dates, especially the proposed effective date of the opt-out election, as this initiates the two-year commitment.
Any discrepancies or omissions can cause significant delays or outright rejection of your affidavit; Carefully review the attestation regarding private contracts with Medicare beneficiaries; confirm your understanding of the requirements. Use black ink and print legibly if submitting a physical copy. Retain a copy of the completed affidavit for your records. Accuracy safeguards a smooth opt-out process and avoids potential compliance issues.

Private Contracting with Medicare Beneficiaries
Opting out necessitates establishing private contracts with Medicare patients, outlining agreed-upon fees and services, ensuring transparency and a legally sound provider-patient relationship.
The Necessity of a Private Contract
When a provider elects to opt-out of Medicare, a legally sound private contract with each Medicare beneficiary becomes absolutely essential. This isn’t merely a formality; it’s a fundamental requirement dictated by Section 1802 of the Social Security Act. Since January 1, 1998, physicians have had the option to pursue this route, allowing them to establish direct financial relationships with their patients.
The private contract serves as a clear agreement, detailing the charges for services rendered, which can differ from Medicare’s established fee schedule. Without a properly executed contract before providing services, the provider risks being considered to have accepted assignment, potentially leading to billing complications and legal repercussions. The contract must be in writing and signed by both the provider and the beneficiary, demonstrating a mutual understanding of the financial terms.
Essentially, the private contract replaces Medicare’s payment system with a direct payment arrangement, offering both the provider and patient greater control over healthcare costs and service delivery.
Essential Elements of a Valid Private Contract
A legally defensible private contract, required when opting out of Medicare, must contain specific elements to ensure its validity. First and foremost, it must clearly state the patient is choosing to receive healthcare services from the provider instead of having Medicare pay. The contract needs a precise description of the services covered, along with the associated charges for each service – these charges are not subject to Medicare’s limitations.
Crucially, the contract must explicitly state the patient is responsible for the full payment at the time of service. It should also include a clear explanation of the patient’s right to revoke the contract at any time. Finally, both the provider and the beneficiary must sign and date the contract, signifying their agreement to the terms.
Maintaining meticulous records of these contracts is paramount, as they serve as proof of the agreed-upon financial arrangement.
Patient Acknowledgement and Agreement
A cornerstone of the opt-out process is securing informed consent from Medicare beneficiaries. The patient must explicitly acknowledge they understand the implications of receiving care outside of the Medicare system. This acknowledgement should detail their responsibility for full payment, without Medicare coverage, and the absence of statutory charge limits.
The agreement must clearly state the patient voluntarily chooses to enter into a private financial arrangement with the provider. It’s vital the patient understands their right to revoke this agreement at any point, resuming standard Medicare coverage.
Documentation is key; a signed and dated statement from the patient confirming their understanding and agreement is essential. This demonstrates the patient’s informed decision and protects both the provider and the beneficiary.
Record Keeping Requirements for Private Contracts
Maintaining meticulous records of all private contracts is paramount for providers opting out of Medicare. These records must be readily available for CMS review and demonstrate full compliance with program regulations. Each contract should include a copy of the signed patient acknowledgement and agreement, confirming their informed consent to forgo Medicare benefits.
Providers are required to retain these contracts for a minimum of six years from the date of service, aligning with standard Medicare documentation retention policies. Accurate record-keeping is crucial for defending against potential audits or investigations.
Detailed documentation should include the date of the contract, the services covered, and the agreed-upon charges. Proper organization and accessibility of these records are vital for a smooth audit process.

Submitting the Opt-Out Affidavit
A completed and signed affidavit must be filed with Medicare to initiate the opt-out process. The effective date aligns with submission, and confirmation of receipt is crucial.
Where to File the Opt-Out Affidavit
To officially submit the Medicare Opt-Out Affidavit (CMS Form), practitioners must send it to the designated Medicare administrative contractor (MAC) responsible for processing claims in their jurisdiction. The specific address varies depending on the provider’s location and the services they offer, so verifying the correct mailing address is paramount.
Currently, providers can also submit the affidavit electronically through the Provider Electronic Submission (PES) system, offering a faster and more efficient method. However, electronic submission may require specific software and adherence to established security protocols.
It’s vital to retain a copy of the submitted affidavit for your records, alongside proof of mailing or electronic submission confirmation. Ensure the affidavit is complete and accurately reflects your intent to opt-out of Medicare to avoid delays or rejection of your request. Incorrectly filed affidavits can significantly postpone the effective date of your opt-out election.
Effective Date of the Opt-Out
The effective date of your Medicare opt-out isn’t necessarily the date you submit the affidavit. Generally, the opt-out becomes active on the first day of the month following a 30-day period after the Medicare Administrative Contractor (MAC) receives a complete and valid affidavit. This processing timeframe allows Medicare to update its systems.
However, if the affidavit is received after the 15th of the month, the effective date typically defaults to the first day of the second month following receipt. Therefore, timely submission is crucial for minimizing delays.
Providers should clearly communicate this effective date to their Medicare beneficiaries, ensuring a smooth transition to private contracting. Billing Medicare for services rendered after the effective date will be considered improper and may result in penalties.
Confirmation of Receipt
While Medicare doesn’t automatically issue a confirmation upon receiving your opt-out affidavit, it’s vital to retain proof of submission. This could be a certified mail receipt if you mailed the form, or a confirmation email/delivery receipt if submitted electronically through the CMS portal (if available). Maintaining this documentation is crucial for your records.
If you haven’t received any communication within 60 days of submitting the affidavit, contacting the CMS Expert Help Desk is recommended to inquire about its status. Proactive follow-up can prevent potential billing issues.
Remember, the absence of a confirmation doesn’t invalidate the opt-out, but having proof of submission strengthens your position should any discrepancies arise. Keep your records organized and readily accessible.

Consequences of Opting Out
Opting out allows direct billing to beneficiaries, but requires adherence to statutory charge limits and necessitates valid private contracts with each patient.
Billing Medicare Beneficiaries Directly
When a provider successfully opts out of Medicare, they gain the ability to bill beneficiaries directly for their services. This means the provider assumes responsibility for submitting claims and collecting payment, rather than relying on Medicare’s reimbursement system. However, this freedom comes with crucial stipulations. Providers must establish a private contract with each Medicare beneficiary before rendering services.
This contract outlines the agreed-upon charges, which cannot exceed the Medicare statutory charge limits. Failure to adhere to these limits can result in significant penalties. The provider is then responsible for all billing functions, including generating invoices and managing collections. Detailed record-keeping of these private contracts is essential for compliance and potential audits. Essentially, opting out shifts the financial responsibility to the patient, but demands diligent adherence to specific regulations.
Statutory Charge Limits and Opt-Out
Even after opting out of Medicare, providers are not entirely free from financial regulations when billing beneficiaries directly. A critical aspect of the opt-out process involves adhering to statutory charge limits established by Medicare. These limits represent the maximum amount a provider can charge a beneficiary for a specific service, even within a private contract.

Exceeding these limits can trigger repercussions, potentially including the requirement to refund excess charges to the beneficiary and facing penalties from Medicare. The statutory charge limits are based on the Medicare fee schedule and are subject to periodic updates. Providers must remain informed of these changes to ensure compliance. Maintaining accurate records of charges and comparing them to the current limits is paramount for a successful opt-out arrangement.
Impact on Medicare Claims
Opting out of Medicare fundamentally alters how a provider handles claims for services rendered to Medicare beneficiaries. Once a valid opt-out affidavit is on file, the provider is no longer permitted to submit claims to Medicare for payment on behalf of those beneficiaries. This means the provider assumes full financial responsibility for collecting payment directly from the patient, as outlined in the private contract.
However, it’s crucial to understand that opting out doesn’t eliminate a beneficiary’s right to submit claims to Medicare for reimbursement. Medicare may reimburse the beneficiary, but at the standard Medicare rates, not the provider’s potentially higher private charges. Providers must clearly communicate this to patients before establishing a private contract, ensuring they understand the implications for their out-of-pocket costs.
Re-entering the Medicare Program
After completing the mandatory two-year opt-out period, a provider wishing to re-enter the Medicare program must take specific steps to reinstate their participation. Simply ceasing to opt-out does not automatically restore billing privileges. Providers must actively re-enroll with Medicare and meet all current enrollment requirements, including background checks and credentialing verification.
It’s important to note that re-enrollment isn’t guaranteed and is subject to Medicare’s approval. Any outstanding debts or compliance issues could hinder the re-enrollment process. Providers should allow sufficient time for processing their re-enrollment application to avoid disruptions in billing. A new National Provider Identifier (NPI) may be required in some cases, depending on the circumstances of the initial opt-out and subsequent re-enrollment.
