ICD-10-PCS Code For Superior Mesenteric Artery: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group B424 includes procedures performed to image vascular structures in the superior mesenteric artery. These ICD-10-PCS codes are used for inpatient documentation when computerized tomography is performed with computer reformatted digital display of multiplanar images for the superior mesenteric artery. Accurate coding within the ICD-10-PCS B424 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Superior Mesenteric Artery Computerized Tomography Procedure Overview

This procedure group includes computerized tomography imaging of the superior mesenteric artery within the lower arterial system. These procedures involve acquisition and computer reformatting of multiplanar images from multiple exposures of external ionizing radiation to visualize the artery. Accurate ICD-10-PCS coding of these CT imaging procedures is important for inpatient reimbursement because it documents the exact imaging technique and anatomic target.

When to Use

Use a code from this group when inpatient computerized tomography with computer reformatting is performed specifically to evaluate the superior mesenteric artery. Codes apply when multiplanar digital display images are generated from multiple external ionizing radiation exposures for diagnostic or treatment planning purposes.

Typical Clinical Scenarios

An elderly patient with sudden onset severe abdominal pain, hypotension, and elevated lactate is admitted from the emergency department for suspected acute mesenteric ischemia; rapid inpatient vascular imaging is required to evaluate arterial occlusion or embolus in the superior mesenteric artery and to guide urgent management. A contrast-enhanced CT with computer-reformatted multiplanar images is performed to delineate vessel patency and plan possible endovascular or surgical intervention. Typical codes: B4241ZZ, B4240ZZ
A middle-aged patient with known atherosclerotic disease and chronic postprandial abdominal pain is admitted for diagnostic workup after progressive weight loss and food avoidance; inpatient CT angiography is obtained to assess the superior mesenteric artery for high-grade stenosis versus chronic occlusion as part of elective preprocedural planning. Computer-reformatted multiplanar CT images using appropriate contrast are acquired to map anatomy for potential revascularization. Typical codes: B4241ZZ, B424YZZ
A postoperative inpatient develops unexplained persistent abdominal pain and concern for branch vessel compromise after recent abdominal aortic aneurysm repair; clinicians order focused CT imaging to evaluate the superior mesenteric artery for iatrogenic injury, thrombosis, or compromised flow. High-resolution CT with multiplanar reformats is performed, sometimes using intravascular imaging adjuncts if available, to detect complications and guide further management.
