Description 

It is an expectation that all patients receive care/services from a licensed clinician.  All appropriate supporting documentation, including recent pertinent office visit notes, laboratory data, and results of any special testing must be provided.  If applicable: All prior relevant imaging results and the reason that alternative imaging cannot be performed must be included in the documentation submitted. 

Where a specific clinical indication is not directly addressed in this guideline, medical necessity determination will be made based on widely accepted standard of care criteria. These criteria are supported by evidence-based or peer-reviewed sources such as medical literature, societal guidelines and state/national recommendations.

Purpose
MRI
Magnetic resonance imaging shows the soft tissues and bones. With its multiplanar capabilities, high contrast, and high spatial resolution, it is an accurate diagnostic tool for 
conditions affecting the joint and adjacent structures. 

Special Note

• Plain radiographs must precede MRI evaluation unless otherwise indicated 
• Some indications are for MRI, CT, or MR or CT Arthrogram (more than one should not be approved at the same time)
• If an MR Arthrogram fits approvable criteria below, approve as MRI

Policy  
INDICATIONS FOR UPPER EXTREMITY MRI
Joint or Muscle Pain (1,2)
Negative Findings on Orthopedic Exam and after X-Ray Completed

NOTE: Does not apply to young children (up to age 12)

• Persistent joint or musculotendinous pain unresponsive to conservative treatment*, within the last 6 months which includes active medical therapy (physical therapy, chiropractic treatments, and/or physician supervised exercise**) of at least four (4) weeks
• With progression or worsening of symptoms during the course of conservative treatment

Joint Specific Provocative Exam Tests and Suspected Injuries
Approvable Orthopedic Test

With a positive orthopedic sign, an initial x-ray is always preferred; however, it is not required to approve advanced imaging. A positive sign is weakness or pain. In addition, any test that suggests joint instability requires further imaging (the below list is not all inclusive)

Shoulder Dislocations (16,17,18,19)

• Recurrent
• First time in any of the situations below that increase the risk of repeated dislocation
  • Anterior glenoid or humeral(Hill-Sachs lesion) bone loss on x-ray

• Pathologic fracture on x-ray or CT
• Suspected ligamentous/tendon injury with known fractures on x-ray/CT that may require surgery

Fracture Nonunion (21)
Nonunion or delayed union as demonstrated by no healing between two sets of x-rays. If a fracture has not healed by 4-6 months, there is delayed union. Incomplete healing by 6-8 months is nonunion. CT is the preferred study

Osteochondral Lesions (22,23)

Osteonecrosis (25)
To further characterize a prior abnormal x-ray or CT suggesting osteonecrosis

• Normal x-rays but symptomatic and high-risk (e.g., glucocorticosteroid use, renal transplant recipient, glycogen storage disease, alcohol abuse, sickle cell anemia)
• Known osteonecrosis to evaluate a contralateral joint after initial x-rays 

e.g., Avascular Necrosis (AVN)

Joint Prosthesis/Replacement (26)
Suspected joint prosthesis loosening, infection, or dysfunction, after initial x-rays

Extremity Mass (27)

• Mass or lesion after non-diagnostic x-ray or ultrasound CT is better than MRI to evaluate mass calcification or bone involvement and may complement or replace MRI

Further Evaluation of Indeterminate Findings on Prior Imaging
Unless follow-up is otherwise specified within the guideline

• For initial evaluation of an inconclusive finding on a prior imaging report that requires further clarification
• One follow-up exam of a prior indeterminate MR/CT finding to ensure no suspicious interval change has occurred. (No further surveillance unless specified as highly suspicious or change was found on last follow-up exam.)

Infection of Bone, Joint, or Soft Tissue Abscess (33)

• Abnormal x-ray or ultrasound
• Negative x-ray or ultrasound but with a clinical suspicion of infection based on either of the following:

Post-Operative/Procedural Evaluation
When imaging, physical examination, or laboratory findings indicate joint infection, delayed or non-healing or other surgical/procedural complications.

Evaluation of Known or Suspected Autoimmune Disease

• Further evaluation of an abnormality or non-diagnostic findings on prior imaging
• Initial imaging of a single joint for diagnosis or response to therapy after plain films and appropriate lab tests (e.g., RF, ANA, CRP, ESR)
• To determine change in treatment or when diagnosis is uncertain prior to start of treatment
• Follow-up to determine treatment efficacy in the following:

Brachial Plexopathy (40,41)

• Traumatic Brachial Plexopathy: If mechanism of injury is highly suspicious for brachial plexopathy (such as mid-clavicular fracture, shoulder dislocation, contact injury to the neck (burner or stinger syndrome) or penetrating injury)(42)
• Non-traumatic Brachial Plexopathy when Electromyography/Nerve Conduction Velocity (EMG/NCV) studies are suggestive of brachial plexopathy

NOTE: Either Neck MRI, Shoulder MRI or Chest MRI may be appropriate depending on the location of the injury/plexopathy. Only ONE of these three studies is indicated.

Pediatrics (Up to Age 18)

• Chronic Recurrent Multifocal Osteomyelitis after initial work-up (labs (i.e., CRP/ESR and x-ray)(43,44)
  • Whole body Bone Marrow MRI is more appropriate when multiple joints requested see CAM 735 Bone Marrow MRI

Contraindication and Preferred Studies

• Contraindications and reasons why a CT/CTA cannot be performed may include: impaired renal function, significant allergy to IV contrast, pregnancy (depending on trimester)
• Contraindications and reasons why an MRI/MRA cannot be performed may include: impaired renal function, claustrophobia, non-MRI compatible devices (such as non-compatible defibrillator or pacemaker), metallic fragments in a high-risk location, patient exceeds wight limit/dimensions of MRI machine
