ICD-10-PCS Code For Vertebral Arteries: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group B32G includes procedures performed to image the vertebral arteries using computerized tomography in the bilateral vertebral arterial distribution. These ICD-10-PCS codes are used for inpatient documentation when multiplanar reformatted digital displays are generated from multiple external ionizing radiation exposures of the vertebral arteries. Accurate coding within the ICD-10-PCS B32G group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy for case mix and payment determination.

Vertebral Arteries Computerized Tomography Procedure Overview

This procedure group includes computerized tomography imaging of the vertebral arteries, bilateral, performed using external ionizing radiation to produce reformatted multiplanar digital displays. These procedures target the upper arterial system, specifically the vertebral arteries on both sides of the neck and posterior circulation. Accurate ICD-10-PCS coding of these inpatient imaging procedures ensures the procedure performed is captured correctly and supports appropriate case mix classification and reimbursement.

B	Section	Imaging
3	Body System	Upper Arteries
2	Operation	Computerized Tomography (CT Scan)
G	Body Part	Vertebral Arteries, Bilateral

When to Use

Use a code from this group when inpatient care includes CT imaging specifically performed to evaluate the vertebral arteries with reformatted multiplanar images derived from multiple exposures. These codes apply when the diagnostic or procedural record documents bilateral vertebral artery computerized tomography and generation of digital reformatted displays.

ICD-10-PCS Code	Description
B32G0ZZ	Computerized Tomography (CT Scan) of Bilateral Vertebral Arteries using High Osmolar Contrast
B32G1ZZ	Computerized Tomography (CT Scan) of Bilateral Vertebral Arteries using Low Osmolar Contrast

B32GZ2Z	Computerized Tomography (CT Scan) of Bilateral Vertebral Arteries using Intravascular Optical Coherence
B32GZZZ	Computerized Tomography (CT Scan) of Bilateral Vertebral Arteries

Typical Clinical Scenarios

An elderly patient presents to the emergency department with sudden-onset dizziness, ataxia, and posterior neck pain after a fall; concern for vertebrobasilar ischemia or traumatic vertebral artery injury prompts inpatient workup. A contrast-enhanced CT angiography with multiplanar reformatted images of both vertebral arteries is obtained to evaluate for dissection, occlusion, or traumatic extravasation. Typical codes: B32G1ZZ, B32GYZZ
A middle-aged patient admitted electively for evaluation of progressive transient ischemic attacks localized to posterior circulation; noninvasive tests are inconclusive and detailed vascular anatomy is needed before neurovascular intervention. Inpatient CT angiography of the bilateral vertebral arteries with computer reformatted multiplanar displays is performed to define stenosis, atherosclerotic plaque, or vascular variants. Typical codes: B32G0ZZ, B32G1ZZ
A patient hospitalized after endovascular stenting of a cervical vertebral artery returns with new neurological symptoms concerning for in-stent restenosis or thrombosis; urgent imaging is required to assess patency and guide further management. A bilateral vertebral artery CT with reformatted multiplanar images is performed, often using contrast, to visualize the stent and vessel lumen. Typical codes: B32GYZZ, B32G1ZZ
