CPT 70472: CT Cerebral Perfusion Analysis (add-on)

Medicare pays $109 on average nationally for this procedure.

CPT code 70472 describes CT cerebral perfusion analysis performed at the same session as a head CT or CTA; the service includes imaging with and without contrast and image postprocessing to measure regional brain blood flow and is an add-on imaging study reported alongside a primary head CT or CTA, typically provided in an outpatient radiology or hospital imaging setting during the same encounter as the primary CT/CTA.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult presenting to the emergency department with acute neurologic deficits such as sudden hemiparesis, aphasia, or altered consciousness suspicious for acute ischemic stroke. After rapid triage and noncontrast head CT to exclude hemorrhage, the ordering provider requests a CT angiography (CTA) of the head and neck to assess vessel occlusion and, at the same session, CT cerebral perfusion analysis to evaluate areas of reduced cerebral blood flow, cerebral blood volume, and mean transit time. The CT perfusion service 70472 is performed during the same imaging encounter as the primary head CT or CTA and includes acquisition with and without contrast plus postprocessing to generate perfusion maps. Typical workflow: emergency clinician orders stroke protocol CT → patient transported to CT suite → technologist performs noncontrast CT ± CTA → contrast bolus and dynamic perfusion acquisition performed → radiologist or trained imaging specialist performs postprocessing and interprets perfusion maps to guide acute reperfusion decisions (e.g., thrombectomy candidacy, IV thrombolysis window extension). Typical site of service is the hospital-based emergency department and inpatient radiology department with CT capability; outpatient imaging centers may perform this if appropriate for non-emergent indications.

CPT Code	Description	Relationship to This Procedure
`70450`	Computed tomography, head or brain; without contrast material	Often the initial noncontrast study in stroke evaluation performed immediately prior to perfusion imaging.
`70460`	Computed tomography, head or brain; with contrast material(s)	May be performed when contrast-enhanced imaging is needed in addition to noncontrast CT and perfusion.
`70496`	Computed tomography, angiography, head/neck, with contrast and image postprocessing; without CT perfusion	CTA of head/neck is commonly performed alongside perfusion; `70472` is an add-on for perfusion analysis performed at the same session.
`70544`	Magnetic resonance imaging, brain (MR), without contrast material, followed by with contrast material and further sequences (dynamic perfusion-specific MR codes exist but CT perfusion is distinct)	MR perfusion is an alternative modality; listed for clinical workflow alternatives but not billed with `70472` in same session.
