Head and Neck CTA With CTP Analysis
Fall 2025 pages 7-15 CLINICAL EXAMPLE 2 Head and Neck CTA With CTP Analysis CLINICAL INDICATION A 76-year-old male presents with right-sided facial droop and weakness concerning for a stroke. PROCEDURE Computed tomography (CT) angiography (CTA) of the head was performed without and with contrast, neck CTA with contrast, and CT cerebral perfusion (CTP) imaging with contrast. TECHNIQUE CTA of the head and neck was performed from the skull base to the skull vertex without intravenous (IV) contrast and from the aortic arch to the skull vertex with IV contrast. Three-dimensional (3D) CTA images were generated. CT perfusion of...

Article Overview
This premium article explains how a head and neck CTA with cerebral perfusion analysis is documented and coded for stroke-related imaging cases. It is aimed at coders, radiology staff, and billing professionals who need to understand the applicable CPT and ICD-10-CM reporting framework, the transition to newer CPT codes in 2026, and the related MIPS references discussed in the example and analysis. The article also addresses imaging-session scope, post-processing concepts, and how the cited guidance changes across effective dates.
Why This Topic Matters
Accurate reporting of advanced stroke imaging depends on matching the documented study type to the correct code set and effective date. This article helps readers follow the coding framework used for combined vascular and perfusion imaging and understand the surrounding policy context.
