Because the neurologist generally will not have confirmed a stroke diagnosis (434.91, Cerebral artery occlusion, unspecified; with cerebral infarction) prior to testing, you must rely on signs and symptoms diagnoses to support medical necessity for diagnostic scans, says Marvel J. Hammer, RN, CPC, CHCO, owner of MJH Consulting, a healthcare reimbursement consulting firm in Denver.

Typical signs and symptoms for stoke victims include cerebral atherosclerosis (437.0), paralysis (344.9), hemiplegia (342.91), loss of vision (369.9), occlusion of arteries (434.9x or 433.1x, as applicable), transient cerebral ischemia (435.9), aneurysms (442.9), stenosis (447.1), speech problems (784.5), and injury to blood vessels (904.9), among others.
