ICD-10-PCS Code For Colic Artery, Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0477 includes procedures performed to dilate arterial structures in the left colic artery. These ICD-10-PCS codes are used for inpatient documentation when an endovascular or open dilation of the left colic artery is performed to restore or improve luminal patency. Accurate coding within the ICD-10-PCS 0477 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Colic Artery, Left Dilation Procedure Overview

This procedure group includes dilation of the left colic artery within the lower arteries body system. Procedures involve expanding the lumen of the left colic artery to improve blood flow to the colon and may use catheters, balloons, or other intravascular devices. Accurate inpatient coding of these dilation procedures is important to reflect the intervention performed and to support appropriate reimbursement and clinical documentation.

Typical Clinical Scenarios

An 82-year-old patient presents to the hospital with acute-onset left lower quadrant abdominal pain and hematochezia. CT angiography demonstrates high-grade focal stenosis of the left colic artery with signs of impending ischemia to the distal descending colon; symptoms are progressive despite medical management. An urgent endovascular dilation of the left colic artery is performed using percutaneous balloon angioplasty with placement of a single drug-eluting stent to restore luminal patency and reduce restenosis risk. Typical codes: 0477341, 047734Z
A 68-year-old patient with progressive exertional abdominal pain and weight loss undergoes elective evaluation for chronic mesenteric ischemia. Angiography identifies moderate-to-severe stenosis localized to the left colic artery; the team elects planned percutaneous endovascular dilation with balloon angioplasty alone to improve mesenteric perfusion and relieve symptoms. The scheduled inpatient procedure is performed via a percutaneous approach using a drug-coated balloon to minimize neointimal hyperplasia. Typical codes: 04773DZ, 04773Z1
A 74-year-old patient with prior endovascular intervention to the left colic artery returns with recurrent postprocedural symptoms and angiographic evidence of in-stent restenosis. During an inpatient revision procedure, the left colic artery undergoes repeat dilation and placement of two intraluminal devices to address recurrent narrowing and reestablish adequate flow to the colon. The intervention is performed percutaneously with implantation of two drug-eluting devices. Typical codes: 047735Z, 04773EZ
