Summary
This policy establishes that CT perfusion imaging of the brain is only considered medically necessary for selecting patients with anterior large-vessel stroke for mechanical embolectomy. All other uses of CT perfusion imaging are considered investigational and not covered.
Action Required
Immediately: Billing team must verify that CT perfusion imaging claims are only submitted for patients with anterior large-vessel stroke who are candidates for mechanical embolectomy. Ensure proper documentation of stroke type and treatment plan is included with claims. Claims for other indications (subarachnoid hemorrhage, brain tumors, head trauma) will likely be denied as investigational.
