DESCRIPTION:

Magnetic resonance angiography (MRA) is a noninvasive imaging technology used for the evaluation and imaging of vessels in the head and neck. MRA may be performed after abnormal results are found on carotid duplex imaging. A contrast agent (gadolinium) may be used to enable visualization of a body system or body structure and may be used in individuals who have a history of contrast allergy and who are at high risk of kidney failure.

POSITION STATEMENT:

Documentation Requirements

Documentation containing the medical necessity of the magnetic resonance angiography (MRA) of the neck and imaging results (e.g., images, clinical reports) should be maintained in the member’s medical record. Documentation may be requested as part of the review process.

Magnetic resonance angiography (MRA) of the neck meets the definition of medical necessity for the following:

Evaluation of vascular disease:

• Evaluation of members with an abnormal ultrasound of the neck or carotid duplex imaging

• Evaluation of head trauma in a member with closed head injury for suspected carotid or vertebral artery dissection

Evaluation of known or suspected tumor/mass:

• Evaluation of carotid body tumors (also called paragangliomas)

• Evaluation of pulsatile neck mass

Pre-operative evaluation:

• Pre-operative evaluation for surgery (e.g., carotid endarterectomy)

Post-operative/procedural evaluation (e.g., carotid endarterectomy):

A follow-up study may be needed to help evaluate a member’s progress after treatment, procedure, intervention or surgery. Documentation requires a medical reason that clearly indicates why additional imaging is needed for the type and area(s) requested.

Indications for combination studies:

Neck MRA/Brain MRA:

• Evaluation of members who have had a stroke or transient ischemic attack (TIA) within the past 2 weeks

• Evaluation of members with a sudden onset of one-sided weakness, inability to speak, vision defects or severe dizziness

• Evaluate suspected vertebral basilar insufficiency (VBI) with symptoms such as vision changes, vertigo, abnormal speech

Evaluation of head trauma in a member with closed head injury for suspected carotid or vertebral artery dissection

Neck MRA/Brain MRI:

Confirmed carotid occlusion of >60%, surgery or angioplasty candidate (significant lesion can flip off emboli, looking for stroke)
