NCDs and coverage provisions in interpretive manuals are not subject to the LCD Review Process (42 CFR 405.860[b] and 42 CFR 426 [Subpart D]). In addition, an administrative law judge may not review an NCD. See §1869(f)(1)(A)(i) of the Social Security Act.

Magnetic Resonance Imaging (MRI) is used to diagnose a variety of central nervous system disorders. Unlike computed tomography (CT) scanning, MRI does not make use of ionizing radiation or require iodinated contrast material (known for causing hypersensitivity reactions and nephrotoxicity in susceptible patients) to distinguish normal from pathologic tissue. Rather, the difference in the number of protons contained within hydrogen-rich molecules in the body (water, proteins, lipids, and other macromolecules) determines recorded image qualities and makes possible the distinction of spinal cord from intra- vertebral disc, tumor from normal tissue, and flowing blood within vascular structures.
MRI is able to image in multiple planes, a distinct advantage in the diagnosis of spinal cord and vertebral column anomalies. MRI is also superior to myelography, a riskier, more uncomfortable, and less informative procedure than MRI.
Medicare will consider Magnetic Resonance Imaging of the Spine medically reasonable and necessary when used to aid in the diagnosis and to assist in therapeutic decision making of the following:
• Lesions in the spinal cord;
• Syringomyelia;
• Spinal cord demyelination or inflammation;
• Tumors of the spine and spinal cord;
• Spinal cord infarcts;
• Spinal trauma;
• Discitis and osteomyelitis;
• Epidural abscess;
• Spinal dysraphism and other developmental abnormalities of the spine;
• Spinal stenosis;
• Spinal cord compression and post-operative scarring;
• Herniation of disc;
• Where soft tissue contrast is necessary;
• When bone artifacts limit CT, or coronal, coronosagittal or parasagittal images are desired; and/or
• For procedures in which iodinated contrast material are contraindicated.
Contraindications:
The 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.
• MRI during a viable pregnancy is also contraindicated at this time.
• The danger inherent in bringing ferromagnetic materials within range of MRI units generally constrains the use of MRI on acutely ill patients requiring life support systems and monitoring devices that employ ferromagnetic materials.
• In addition, the long imaging time and the enclosed position of the patient may result in claustrophobia, making patients who have a history of claustrophobia unsuitable candidates for MRI procedures.
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.

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.

General Information
Documentations Requirements
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 to Medicare 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.
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 study. The physician must state the clinical indication/medical necessity for the study in his order for the test.
