Authorization and Documentation Requirements

Prior Authorization

Prior Authorization Required

Prior authorization is required for all neck, face, or orbit MRI procedures. The requesting provider must submit the required information before authorization review.

Applies to all neck, face, or orbit MRI procedures.
Submit a standard written order, medical-record information and medical-necessity documentation, and correct service coding.

Documentation Required

TMJ Trauma: Indeterminate Preliminary Imaging

MRI for TMJ trauma is medically necessary when assessment of meniscal position and integrity is needed and the preliminary plain X-ray or CT scan is indeterminate.

Document trauma to the TMJ and the need to assess meniscal position and integrity.
Submit the indeterminate plain X-ray or CT result as part of the preliminary-imaging pathway.

Clinical Context

MRI of the neck, face, and orbit is used to evaluate infection, trauma, masses, and abnormalities involving the external eye and nose. It may also support therapy planning and follow-up for face and neck neoplasms, evaluation of vocal-cord lesions, and assessment of cervical lymphadenopathy. Cancer-related imaging is evaluated using NCCN as a primary reference together with current medical references and specialty-society guidance.
