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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 047B includes procedures performed to dilate arterial lumens in the inferior mesenteric artery. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs an endoluminal or angioplasty-type dilation to restore patency of the inferior mesenteric artery. Accurate coding within the ICD-10-PCS 047B group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and supports clinical documentation accuracy.

Inferior Mesenteric Artery Dilation Procedure Overview

Procedures in the ICD-10 PCS 047B group involve dilation of the inferior mesenteric artery, a lower arteries target that supplies blood to portions of the large intestine. These procedures expand the lumen of the artery to restore or improve blood flow through the inferior mesenteric artery. Accurate ICD-10-PCS coding ensures inpatient records reflect the specific vascular intervention and supports correct case mix assignment and reimbursement.

When to Use

Use a code from this group when an inpatient procedure specifically performs dilation of the inferior mesenteric artery to treat stenosis or occlusion affecting colonic perfusion. Do not use these codes for diagnostic angiography alone or for procedures on other arterial branches.

Typical Clinical Scenarios

An elderly patient with known atherosclerotic peripheral vascular disease presents with acute-onset severe abdominal pain and signs of colonic ischemia. Imaging reveals critical stenosis of the inferior mesenteric artery causing compromised perfusion; during urgent endovascular intervention the team performs balloon angioplasty without stent placement to restore lumen patency. A percutaneous approach using a drug-coated balloon is chosen to reduce restenosis risk in this high-risk vascular territory. Typical codes: 047B3Z1
A middle-aged patient with chronic progressive claudication-like left lower quadrant postprandial pain and weight loss undergoes elective vascular intervention for symptomatic high-grade inferior mesenteric artery stenosis diagnosed on elective angiography. The planned inpatient procedure is percutaneous placement of a single drug-eluting intraluminal stent following dilation to improve long-term vessel patency. The elective nature allows use of a percutaneous intraluminal device with drug-eluting properties. Typical codes: 047B341
A patient previously treated with angioplasty for inferior mesenteric artery stenosis returns with recurrent mesenteric ischemia symptoms and imaging-confirmed restenosis at the prior treatment site. During the inpatient re-intervention the surgeon deploys two intraluminal devices to scaffold the artery after repeat dilation to re-establish durable flow. The case represents a revision of prior endoluminal therapy requiring placement of multiple devices. Typical codes: 047B3EZ
