Billing and coding guidance in this policy complements and references Local Coverage Determination L34425; claims should be supported per the documentation requirements specified in LCD L34425.
The medical record must document the medical necessity for performing MRI of the brain in addition to MRI of the orbit, face, and/or neck when both procedures are done on the same day.
Pre-imaging documentation should include screening for contraindications (presence/absence of implanted neurostimulators, cochlear implants, pacemakers per CMS guidance, retained metal fragments in the eye, magnetic ocular implants, and intracranial aneurysm clips).
When contrast material is administered, documentation should support the clinical indication for contrast-enhanced MRI.

No specific clinical indications are listed in this billing/coding guidance; coverage determinations for MRI of the head and neck follow Local Coverage Determination L34425.
MRI of the orbit, face, and/or neck is medically reasonable and necessary to diagnose or characterize pathology of the eye, nasopharynx, oropharynx, and neck including tumors, infection, soft-tissue pathologies, and congenital abnormalities.
MRI with intravenous gadolinium-based or other indicated contrast agents may be used when contrast enhancement is required to visualize a body system or structure.
An MRI of the brain may be performed on the same day as MRI of the orbit, face, and/or neck when clinically necessary, provided the medical record documents the medical necessity for both procedures.
