Diagnostic examinations of joint(s) performed on Magnetic Resonance Imaging (MRI) units are covered if they are:

  • Reasonable and medically necessary for the individual patient.
  • Performed on a unit that has received federal FDA approval. Such a unit(s) must be operated within the parameters specified by that approval.
  • Compliant with ACR quality standards. Note: Refer to the guidelines listed below for office-based MRI.

Office-Based MRI

In order to maintain appropriate quality in office-based MRI, the MRI Accreditation Program Requirements serve as a pertinent performance benchmark, and, using such as a reference document, it is intended that the following guidelines be followed with respect to:
Staff Competency
A provider who performs the interpretation and written report of an MRI of a joint (professional component) must possess the knowledge, skills, training and experience minimally necessary for this component of the service. Medicare coverage of these services is conditional on the competence of the individual who performs and interprets the service. Medicare expects that any provider who seeks and receives payment for the professional components of these radiographic services will be prepared to substantiate his training and/or experience if asked by Medicare to do so. Numerous pathways for achieving and maintaining competency for providing these services by physicians and technologists exist.
The qualified physician’s continuing education should be in accordance with the ACR Practice Guideline for Continuing Medical Education (CME) or should include CME in MRI as is appropriate to the physician’s practice needs.Technologists practicing MRI scanning should be licensed in the jurisdiction in which he/she practices, if state licensure for MRI technologists exists. The continuing education for a technologist should be 15 hours of Category A CME in MRI every three years.
An MRI of a joint may be personally performed by a physician or a technologist. When performed by a technologist,one of the following standards must be met:
  • Facility must be accredited for MRI by the American College of Radiology (ACR)
  • For testing performed in non-ACR accredited office facilities, the technologist must have received credentials in MRI technology as a Certified Radiologic Technologist (CRT) from the American Registry of Radiologic Technologists (ARRT).


Coverage Guidance

Coverage Indications, Limitations, and/or Medical Necessity

    Magnetic Resonance Imaging (MRI) is a non-invasive imaging technique used for a variety of diagnostic visualizations.

    MRI provides superior tissue contrast when compared to CT, is able to image in multiple planes, is not affected by bone artifact, provides vascular imaging capability, and makes use of safer contrast media.

    MRI can enhance diagnostic sensitivity and facilitate early diagnosis in a limited number of articular disorders and is indicated in selected circumstances when conventional radiography is not adequate.

    MRI of any joint of the lower extremities (73721-73723) will be considered medically reasonable and necessary under the following conditions:

    · Avascular necrosis;

    · Osteomyelitis;

    · Intraarticular derangement; and

    · Villonodular synovitis.

    Contraindications and non-covered uses

    MRI is not covered when the following patient-specific contraindications are present:

    • MRI is not covered for patients with cardiac pacemakers or with metallic clips on vascular aneurysms unless the Medicare beneficiary meets the provisions of the following exceptions:

    Effective for claims with dates of service on or after July 7, 2011, the contraindications will not apply to pacemakers when used according to the FDA-approved labeling in an MRI environment, or effective for claims with dates of service on or after February 24, 2011, CMS believes that the evidence is promising although not yet convincing that MRI will improve patient health outcomes if certain safeguards are in place to ensure that the exposure of the device to an MRI environment adversely affects neither the interpretation of the MRI result nor the proper functioning of the implanted device itself. We believe that specific precautions (as listed below) could maximize benefits of MRI exposure for beneficiaries enrolled in clinical trials designed to assess the utility and safety of MRI exposure. Therefore, CMS determines that MRI will be covered by Medicare when provided in a clinical study under section 1862(a)(1)(E) (consistent with section 1142 of the Act) through the Coverage with Study Participation (CSP) form of Coverage with Evidence Development (CED) if the study meets the criteria in each of the three paragraphs in CMS Pub 100-03, CMS National Coverage Determination Manual, Chapter 1, Section 220.2.C.1.

    · Patients with a viable pregnancy.

    · Patients with devices containing ferromagnetic materials.

    · Patients who are claustrophobic.

    Nationally Non-Covered Indications:


    CMS has determined that MRI of cortical bone and calcifications, and procedures involving spatial resolution of bone and calcifications, are not considered reasonable and necessary indications within the meaning of section 1862(a)(1)(A) of the Act, and are therefore non-covered.

Quality Control and Quality Assurance
There should be a well-documented office protocol for performing continuous quality control testing of instrumentation in tandem with periodic preventive maintenance, which is also properly documented in service records maintained by the MRI site. In addition, appropriately documented physician peer-review activities should be an integral portion of the staff competency guidelines discussed above.
The choice of the appropriate imaging modality should be determined at an individual level. In some cases, MRI may be an appropriate initial choice; in others, standard X-rays should be used for the initial evaluation. Generally, MRI of a joint is considered medically necessary when the following disorders are present or suspected and/or the necessary information is not available from standard X-rays. Joint MRIs are indicated for the following clinical conditions:
  • Tumors/masses or swelling involving or contiguous to a joint.
  • Rotator cuff tears or impingement.
  • Joint instability, deformities or internal derangement.
  • Intra-articular osteocartilaginous body(ies).
  • Occult joint injury, e.g., osteochondral injury.
  • Suspected nerve entrapment or mass close to a joint.
  • Suspected ligament or tendon injury.
  • Kienbock’s disease of the wrist.
  • Bone abnormalities of a joint related to soft tissue abnormalities.
  • Occult Avascular Necrosis (AVN) or follow-up of this condition.
  • Acute joint injuries.
  • Actual or suspected infection or inflammation on joints or surrounding structures.
  • Effect of other single or multiple system, non-joint disorders on joints and surrounding structures.
  • Pain/other sensory disturbances in joints or surrounding structures.
  • Weakness/other motor disturbances in joints or surrounding structures.
  • Decreased range of motion; stiffness, popping/clicking, instability or discoordination related to joints and surrounding structures.
  • Characterization of an abnormal finding in joints or surrounding structures detected on another test.
  • Meniscal and/or ligamentous tears.
  • Tendinopathy.
  • Assessment of joints and surrounding structures in preparation for an interventional procedure.
Usually an MRI of a joint is performed when standard X-rays are inconclusive and the patient may have failed a treatment regimen for a disorder clinically diagnosed from medical history and examination. MRIs of a joint are generally not indicated when a surgical exploration of the joint (arthroscopic or open) will be performed regardless of the results of the MRI, unless the MRI results are to be used to provide information for planning the optimal surgical approach.
The clinical necessity of performing a joint MRI must be noted in the medical record or easily inferred from the medical record. Screening imaging or unnecessary duplication of imaging is not considered medically necessary.
There are relative contraindications to MRI scanning. These include cardiac pacemakers, ferromagnetic clips, intraocular metal and cochlear implants. MRI scanning under these circumstances is only covered when the medical situation is clearly explained.

Contractors shall consider a service to be reasonable and necessary if the contractor determines that the service is:
  • Safe and effective.
  • Not experimental or investigational (exception: routine costs of qualifying clinical trial services with dates of service on or after September 19, 2000, which meet the requirements of the clinical trials NCD are considered reasonable and necessary).
  • Appropriate, including the duration and frequency that is considered appropriate for the service, in terms of whether it is:
    • Furnished in accordance with accepted standards of medical practice for the diagnosis or treatment of the patient’s condition or to improve the function of a malformed body member.
    • Furnished in a setting appropriate to the patient’s medical needs and condition.
    • Ordered and furnished by qualified personnel.
    • One that meets, but does not exceed, the patient’s medical need.
    • At least as beneficial as an existing and available medically appropriate alternative.

Bill Type Codes
Contractors may specify Bill Types to help providers identify those Bill Types typically used to report this service. Absence of a Bill Type does not guarantee that the policy does not apply to that Bill Type. Complete absence of all Bill Types indicates that coverage is not influenced by Bill Type and the policy should be assumed to apply equally to all claims.
12X, 13X, 18X, 21X, 22X, 23X, 71X, 83X, 85X
Revenue Codes
Contractors may specify Revenue Codes to help providers identify those Revenue Codes typically used to report this service. In most instances Revenue Codes are purely advisory; unless specified in the policy services reported under other Revenue Codes are equally subject to this coverage determination. Complete absence of all Revenue Codes indicates that coverage is not influenced by Revenue Code and the policy should be assumed to apply equally to all Revenue Codes.

CPT/HCPCS Codes

Documentation Requirements
Documentation supporting medical necessity should be legible, maintained in the patient’s medical record and made available to Medicare upon request.


The documentation of the study requires a formal written report, with clear identifying demographics, the name of the interpreting provider, reason for the test, and interpretive report and copies of all images obtained. The computerized data with image reconstruction should also be maintained.

    The medical record must contain documentation, including a written or electronic request for the procedure which fully supports the medical necessity of the procedure performed. This documentation includes, but is not limited to relevant medical history, physical examination, diagnosis (if known), pertinent signs and symptoms and results of pertinent diagnostic tests and/or procedures. This entire documentation-not just the test report or the findings/diagnosis on the order, must be made available upon request.

    When a CT scan and MRI are performed on the same day for the same anatomical area, the medical record must clearly reflect the medical necessity for performing both tests.

    Rules for Testing Facility to Furnish Additional Tests:
    If the testing facility cannot reach the treating physician/practitioner to change the order or obtain a new order and documents this in the medical record, then the testing facility may furnish the additional diagnostic test if all of the following criteria apply:

        The testing center performs the diagnostic test ordered by the treating physician/practitioner;
        The interpreting physician at the testing facility determines and documents that, because of the abnormal result of the diagnostic test performed, an additional diagnostic test is medically necessary;
        Delaying the performance of the additional diagnostic test would have an adverse effect on the care of the beneficiary;
        The result of the test is communicated to and is used by the treating physician/practitioner in the treatment of the beneficiary; and
        The interpreting physician at the testing facility documents in his/her report why additional testing was done.


    Rules for Testing Facility Interpreting Physician to Furnish Different or Additional Tests:

    The following applies to an interpreting physician of a testing facility who furnishes a diagnostic test to a beneficiary who is not a hospital inpatient or outpatient. The interpreting physician must document accordingly in his/her report to the treating physician/practitioner.

    Test Design:
    Unless specified in the order, the interpreting physician may determine, without notifying the treating physician/practitioner, the parameters of the diagnostic test (e.g., number of radiographic views obtained, thickness or tomographic sections acquired, use or non-use of contrast media).


    If the provider of the service is other than the ordering/referring physician, that provider must maintain hard copy documentation of test results and interpretation, along with copies of the ordering/referring physician's order for the studies. The physician must clearly state the clinical indication/medical necessity for the study in the order for the test.
