Diagnostic imaging
Reports contrast-enhanced cerebral CT perfusion analysis when performed with CT and CTA, commonly during imaging evaluation of suspected acute stroke.
This service adds cerebral perfusion analysis to contrast-enhanced head imaging that includes CT and CTA. Perfusion processing produces maps of cerebral blood flow and related measures that can help clinicians assess suspected acute ischemic stroke and impaired brain perfusion. A radiologist typically interprets the study in a hospital or imaging facility; acquisition and postprocessing require the appropriate CT equipment and staff.
Report 70472 only with its designated primary procedure, not as a stand-alone perfusion service. The record should support contrast-enhanced perfusion acquisition, the associated CT and CTA imaging, postprocessing, and the interpreting physician’s findings. CMS treats it as an add-on paid within the primary procedure’s global period. The diagnostic test may be billed globally, or its interpretation with modifier 26 and its technical service with modifier TC; billing without either modifier represents the global service.

Ct cere prfu aly c+wo ct/cta
Both codes report cerebral perfusion analysis, but 70472 is the variant with CT and CTA, while 70473 is the variant without CT and/or CTA.
70450 reports a noncontrast head CT. It does not represent the contrast-enhanced cerebral perfusion analysis reported by 70472.
Ct angiography head
70496 reports CT angiography of the head. It is not a cerebral perfusion analysis code and does not replace 70472 when perfusion analysis is performed.

70472 is the cerebral perfusion analysis variant that includes CT and CTA. 70473 is the related variant without CT and/or CTA; select according to the imaging actually performed and the code descriptor.
No. CMS identifies it as an add-on code, so it must be reported with its designated primary procedure.
Yes. The interpreting physician may report modifier 26, and the entity providing the equipment and staff may report modifier TC. Without either modifier, the claim represents the global service.
Document the contrast-enhanced cerebral perfusion acquisition, the CT and CTA imaging, the perfusion postprocessing, and the interpretation. The record should also identify the associated primary procedure.
CMS pays 70472 within the global period of its primary procedure. Report it only in conjunction with that primary service.
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
