Does C8910 require prior authorization?

Yes, C8910 requires prior authorization (high confidence). At least one active policy explicitly requires prior authorization.

`C8910`, Magnetic resonance angiography without contrast, chest (excluding myocardium)

HCPCS/CPT

Prior Auth Required

At least one active policy explicitly requires prior authorization (high confidence)

For services requiring a referring/ordering physician, the claim must report the referring/ordering physician's name and NPI.
A valid ICD-10-CM diagnosis code that best describes the patient's condition for which the service was performed must be reported on the claim; claims without a valid code will be returned as incomplete.
For diagnostic MRA tests, report the result of the test if known; if not known, report the symptoms that prompted the test.

MRA is covered to evaluate blood flow in the internal carotid vessels of the head and neck.
MRA of peripheral arteries of the lower extremities is covered to determine the presence and extent of peripheral vascular disease and may substitute for conventional angiography (CA).
MRA is covered for pre-operative evaluation of patients undergoing elective abdominal aortic aneurysm (AAA) repair when it is comparable to CA for determining extent of AAA and evaluating aortoiliac occlusive disease and renal artery pathology necessary for surgical planning.
MRA of the renal arteries and aortoiliac arteries (in the absence of AAA or aortic dissection) is covered when MRA is expected to avoid CA, physician history/physical and standard assessments are insufficient, and obtaining MRA has a high probability of positively affecting patient management.
MRA of the chest is covered for diagnosis of suspected pulmonary embolism when the patient has a contraindication to receiving intravascular iodinated contrast material.
MRA of the chest is covered for pre-operative and post-operative evaluation of thoracic aortic dissection and thoracic aortic aneurysm and may be used as an alternative to other non-invasive imaging when clinically appropriate.
