Can Non-Credentialed Physicians Bill Medicare? Demystifying Enrollment and Payment

No, in most circumstances, non-credentialed physicians cannot directly bill Medicare for services rendered. However, there are specific exceptions and pathways that allow for indirect billing or payment under certain arrangements.

Understanding Medicare Credentialing

The Medicare program, a cornerstone of healthcare in the United States, relies on a network of enrolled and credentialed providers to deliver services to its beneficiaries. Can Non-Credentialed Physicians Bill Medicare? The answer is complex and depends on several factors, primarily related to enrollment status and the nature of the services provided. Medicare enrollment signifies that a physician has met the program’s stringent requirements, including licensing, qualifications, and adherence to specific standards. Without this formal enrollment, direct billing to Medicare is generally prohibited.

Benefits of Medicare Credentialing

Becoming a credentialed Medicare provider unlocks significant advantages:

Direct Reimbursement: Enrolled physicians can directly bill Medicare for services, streamlining the payment process.
Patient Access: Beneficiaries are more likely to seek care from credentialed providers, expanding a physician’s patient base.
Enhanced Reputation: Credentialing signifies adherence to Medicare standards, boosting a physician’s credibility.
Referral Opportunities: Credentialed physicians can readily refer patients to other Medicare providers.

The Medicare Enrollment Process

The Medicare enrollment process is comprehensive and requires careful attention to detail. Here are the general steps involved:

Application Submission: Physicians must complete and submit the required Medicare enrollment application (CMS-855I).
Credential Verification: Medicare thoroughly verifies the physician’s credentials, including licensing, education, and professional history.
Background Checks: Criminal background checks are conducted to ensure the physician meets the program’s integrity standards.
Site Visit (Potentially): In some cases, Medicare may conduct a site visit to assess the physician’s practice location and operations.
Enrollment Approval: Upon successful completion of the verification process, the physician is enrolled as a Medicare provider.

Exceptions to the Rule: When Non-Credentialed Physicians Can Receive Payment

While direct billing by non-credentialed physicians is generally prohibited, some exceptions exist. These scenarios often involve indirect payment mechanisms:

“Incident To” Billing: Services performed by non-credentialed staff, including some physicians, may be billed under the supervising credentialed physician’s National Provider Identifier (NPI). Strict rules apply regarding the level of supervision required and the types of services that qualify.
Locum Tenens Arrangements: A credentialed physician may temporarily use the NPI of another credentialed physician for a limited period (typically 60 days), such as when covering for a physician on leave. This requires specific documentation and notification to Medicare.
Institutional Billing: Hospitals and other institutions may bill Medicare for services provided by physicians they employ, regardless of whether the individual physicians are individually credentialed. The payment goes to the institution, which then compensates the physician.
“Opt-Out” Physicians: Physicians who formally “opt out” of Medicare are not enrolled and cannot bill Medicare directly. Instead, they enter into private contracts with patients, who are responsible for paying the physician directly. Medicare will not reimburse either the patient or the physician.

Common Mistakes to Avoid

Navigating the Medicare enrollment and billing process can be complex. Common mistakes that can lead to claim denials or enrollment delays include:

Incomplete Applications: Ensure all sections of the enrollment application are completed accurately and thoroughly.
Incorrect Information: Double-check all information provided, including NPI, license numbers, and practice addresses.
Failure to Update Information: Keep Medicare informed of any changes to your practice, such as address changes or changes in ownership.
Misunderstanding “Incident To” Rules: Carefully adhere to the guidelines for “incident to” billing, ensuring proper supervision and documentation.
Ignoring Deadlines: Be aware of deadlines for submitting applications and renewals.
Lack of Understanding of Locum Tenens Rules: Strictly adhere to all locum tenens requirements to avoid violating Medicare regulations.

The Importance of Compliance

Adherence to Medicare’s rules and regulations is crucial. Failure to comply can result in penalties, fines, or even exclusion from the Medicare program. Regular audits and reviews are conducted to ensure compliance.

Resources for Physicians

Medicare Learning Network (MLN): Provides educational resources and guidance for healthcare professionals.
Centers for Medicare & Medicaid Services (CMS): Offers comprehensive information about Medicare policies and procedures.
National Government Services (NGS): One of several Medicare Administrative Contractors (MACs) that process claims and provide support to providers. Your regional MAC can provide tailored guidance.
Professional Medical Billing Companies: Hiring an experienced billing company can help navigate the complexities of Medicare billing.

Frequently Asked Questions (FAQs)

If I am not credentialed with Medicare, can I still get paid if a patient pays me directly?

No, unless you have formally opted-out of Medicare. If you are not enrolled and have not opted-out, you are technically obligated to bill Medicare for covered services. If you accept direct payment from a beneficiary, you may be subject to penalties. Opting-out allows you to enter into private contracts with Medicare beneficiaries.

What is “incident to” billing, and how does it allow a non-credentialed physician to be paid?

“Incident to” billing allows services provided by non-credentialed staff, including some physicians, to be billed under the supervising credentialed physician’s NPI. These services must be an integral part of the patient’s treatment course, commonly furnished in a physician’s office, and provided under the direct supervision of a credentialed physician.

How long does the Medicare credentialing process typically take?

The Medicare credentialing process can vary depending on several factors, including the completeness of the application and the workload of the Medicare Administrative Contractor (MAC). On average, it can take anywhere from 3 to 6 months.

What happens if I perform a service that is not covered by Medicare?

If you perform a service that is not covered by Medicare, you can bill the patient directly, but you must provide the patient with advance notice and obtain their agreement to be responsible for the cost. This is typically done using an Advance Beneficiary Notice of Noncoverage (ABN) form.

What is the difference between enrollment and participation in Medicare?

Enrollment refers to the process of becoming a recognized Medicare provider. Participation refers to agreeing to accept Medicare’s allowed amount as full payment for all covered services. Participating providers receive higher reimbursement rates and are listed in Medicare’s online provider directory.

Can a non-credentialed physician supervise a diagnostic test that is billed to Medicare?

In general, no. Supervision of diagnostic tests billed to Medicare typically requires the supervising physician to be enrolled and credentialed with Medicare. Specific requirements may vary depending on the type of test and the setting in which it is performed.

What should I do if my Medicare application is denied?

If your Medicare application is denied, you will receive a notification explaining the reason for the denial. You have the right to appeal the decision. Carefully review the denial notice and follow the instructions for submitting an appeal.

What are the consequences of submitting fraudulent claims to Medicare?

Submitting fraudulent claims to Medicare is a serious offense that can result in severe penalties, including fines, imprisonment, and exclusion from the Medicare program. It is essential to ensure that all claims submitted are accurate and truthful.

How often do I need to revalidate my Medicare enrollment?

Medicare requires providers to revalidate their enrollment periodically, typically every five years. This process helps ensure that the information on file with Medicare is accurate and up-to-date.

If I work as a hospital employee, do I still need to be individually credentialed with Medicare?

In many cases, no. Hospitals can bill for services provided by their employed physicians under the hospital’s provider number. However, some hospitals may still require their physicians to be individually credentialed with Medicare for certain purposes. Check with your employer.

Is it possible to bill Medicare for services provided outside of the United States?

Generally, Medicare does not cover services provided outside of the United States. There are limited exceptions, such as for emergency services in Canada or Mexico under specific circumstances.

How can I find out if a physician is credentialed with Medicare?

You can use the Medicare Provider Directory on the CMS website to search for credentialed physicians. The directory provides information about providers who are enrolled and participating in Medicare. Can Non-Credentialed Physicians Bill Medicare? This directory helps patients confirm a provider’s enrollment status.
