    MUSCULOSKELETAL IMAGING GUIDELINES

    MS-1~GENERAL GUIDELINES

    A current clinical evaluation (within 60 days) is required before advanced imaging can be considered.

    The clinical evaluation should include a relevant history and physical examination, appropriate laboratory studies, and non-advanced imaging modalities such as x-ray. o Other meaningful contact (telephone call, electronic mail or messaging) by an

    established patient can substitute for a face-to-face clinical evaluation. o A clinical diagnosis for many musculoskeletal bone, joint and soft tissue pain,

    and injury disorders are based on examination and plain x-ray.

    Many episodes of pain, particularly those involving the joints, should be evaluated with appropriate plain x-rays and then managed with at least 6 weeks of non-surgical care prior to considering advanced imaging.

    Conservative treatment may include NSAIDS, oral steroids, injection; a physician directed home exercise program or physical therapy, or bracing/immobilization.

    Orthopedic specialist evaluation can be helpful in determining the need for advanced imaging. o The need for repeat advanced imaging should be carefully considered and may not

    be indicated if prior imaging has been performed. o Serial advanced imaging, whether CT or MRI, for surveillance of healing or

    recovery from musculoskeletal disease is not supported in the majority of musculoskeletal conditions.

    Computer-Assisted Musculoskeletal Surgical Navigation Procedures: The Category III code used to describe computer-assisted navigation in orthopedic

    surgery with CT/MRI image guidance is: +0055T. o Computer-assisted navigation (CAN) in orthopedic procedures describes the use of

    computer-enabled tracking systems to facilitate alignment in a variety of surgical procedures and verification of an intended implant placement.

    o Code +0055T is intended to be used in addition to the code for the primary surgical procedure.

    o CT/MRI imaging acquisition for preoperative planning, in the absence of written payor instructions, is not to be reported with a diagnostic CT or MRI code

    MUSCULOSKELETAL IMAGING GUIDELINES

    MS-2~Imaging Techniques

    Plain X-Ray

    Should be done prior to advanced imaging in most musculoskeletal conditions to rule out those situations that do not require advanced imaging, such as osteoarthritis, acute/healing fracture, dislocation, osteomyelitis, acquired/congenital deformities, and tumors of bone amenable to biopsy or radiation therapy (in known metastatic disease), etc.

    MRI or CT

    MRI is often the preferred imaging modality in musculoskeletal conditions because it is superior in imaging the soft tissues and can also define physiological processes in some instances, e.g. edema, loss of circulation (AVN), and increased vascularity (tumors).

    CT is better at imaging bone and joint anatomy; thus, it is useful for studying complex fractures (particularly of the joints and vertebra), dislocations, and assessing delayed union or non-union of fractures if plain x-rays are equivocal. CT may be the procedure of choice in patients who cannot have MRI, such as those with pacemakers.

    Contrast Issues

    Most musculoskeletal imaging (MRI or CT) is without contrast, except for the following: o Tumors and osteomyelitis (without and with contrast) o Post-MR arthrography (with contrast only) o MRI for rheumatoid arthritis (contrast as requested) o In postoperative MRIs of the joints, MRI arthrography can be approved if

    requested, MRI without contrast is indeterminate.

    PET At the present time there is inadequate evidence to support the medical necessity of

    this study for the routine assessment of musculoskeletal disorders, other than for neoplastic disease. It should be considered experimental or investigational and will be forwarded to Medical Director Review.

    MS-3~3D RENDERING

    Indications for musculoskeletal 3-D image post-processing: o Complex fractures (comminuted or displaced) of any joint or the pelvis/acetabulum o Spine fractures o Preoperative planning when conventional imaging is insufficient

    The code assignment for 3-D rendering depends upon whether the 3-D post-processing is performed on the scanner workstation (CPT76376) or on an independent workstation (CPT76377). o 2-dimensional reconstruction (i.e., reformatting axia
