Home » Resources » Does Medicare Cover a Knee MRI?

We understand the importance of obtaining accurate and reliable information when it comes to Medicare coverage for medical procedures. In this article, we aim to provide you with a comprehensive guide to whether Medicare covers a knee MRI. We will delve into the various aspects of Medicare coverage, eligibility requirements, and other essential details to help you make informed decisions about your healthcare needs.

Understanding Medicare Coverage

Medicare is a federal health insurance program primarily designed for individuals aged 65 and older, as well as certain younger individuals with disabilities or specific medical conditions. It consists of different parts, namely Part A, Part B, Part C (Medicare Advantage), and Part D (prescription drug coverage).

Medicare Part B and Diagnostic Imaging

When it comes to diagnostic imaging, such as a knee MRI, Medicare Part B typically provides coverage. Medicare Part B is the component of Medicare that covers outpatient services, including medically necessary diagnostic tests, procedures, and preventive services.

Criteria for Medicare Coverage of a Knee MRI

To determine whether Medicare will cover a knee MRI, certain conditions must be met. First and foremost, the knee MRI must be deemed medically necessary by a qualified healthcare provider. The physician or specialist must establish that the MRI is essential for diagnosing or evaluating a specific medical condition related to the knee joint.

Furthermore, the knee MRI should be performed at a facility that accepts Medicare assignment. Medicare assignment means that the facility has agreed to accept the Medicare-approved amount as full payment for the services rendered. It is essential to verify with the healthcare provider or facility in advance to ensure they accept Medicare assignment.

Medicare Coverage and Cost

Under Medicare Part B, coverage for a knee MRI is typically provided at 80% of the Medicare-approved amount. Beneficiaries are responsible for the remaining 20% coinsurance. It’s worth noting that deductibles and other factors may apply, so it’s always advisable to review your specific Medicare plan details or contact Medicare directly for precise information regarding costs and coverage.

Additional Considerations

While Medicare coverage for knee MRIs is generally available, it is crucial to understand that certain limitations or exceptions may apply. For example, if a knee MRI is performed for screening purposes rather than to diagnose or evaluate a medical condition, Medicare coverage may not be extended.

It’s also important to note that coverage rules and guidelines may vary depending on your specific Medicare plan or location. Therefore, we highly recommend consulting with your healthcare provider or contacting Medicare directly to obtain accurate and up-to-date information regarding your coverage options.


In conclusion, Medicare Part B generally covers knee MRIs when deemed medically necessary by a qualified healthcare provider. However, it’s crucial to confirm that the knee MRI will be performed at a facility that accepts Medicare assignments. Understanding the coverage criteria and potential costs associated with a knee MRI under Medicare can help you make informed decisions about your healthcare needs.

In case you have further questions or require more specific information regarding Medicare coverage for knee MRIs, we encourage you to reach out to your healthcare provider or contact Medicare directly. Their expertise and resources will provide you with the most accurate and up-to-date information tailored to your unique situation.
