ICD-10-PCS Code For Gastric Artery: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 04L2 includes procedures performed to occlude arterial structures in the gastric artery. These ICD-10-PCS codes are used for inpatient documentation when a complete closure of the gastric artery lumen is performed to stop blood flow. Accurate coding within the ICD-10-PCS 04L2 group is essential for proper inpatient reimbursement, as it captures procedure performed and determines appropriate case mix and payment.

Gastric Artery Occlusion Procedure Overview

Procedures in this group involve completely closing the lumen of the gastric artery within the lower arterial system to stop blood flow to a targeted gastric territory. These occlusion procedures are performed on the lower arteries and typically involve embolization, ligation, or other occlusive techniques. Accurate coding of these procedures matters for inpatient reimbursement because it captures the definitive vascular intervention provided and supports appropriate case mix assignment.

2	Body Part	Gastric Artery

When to Use

Use a code from this group when a procedure completely closes the gastric artery lumen, such as by embolization or surgical ligation, during an inpatient stay. These codes apply when the primary action is occlusion of the gastric artery rather than partial restriction or repair.

Typical Clinical Scenarios

An elderly patient on warfarin presents to the emergency department with acute upper gastrointestinal hemorrhage and hemodynamic instability secondary to a bleeding gastric artery pseudoaneurysm identified on contrast CT angiography; the patient is admitted for stabilization and definitive endovascular control to stop bleeding by permanently occluding the affected gastric arterial branch. Typical codes: 04L23DZ, 04L23ZZ
A middle-aged patient with recurrent gastric ulcers refractory to medical therapy is scheduled for a planned elective procedure to reduce arterial inflow to a localized gastric region; during the inpatient admission an interventional radiology–guided embolization is performed to occlude the targeted gastric arterial supply permanently. Typical codes: 04L24DZ, 04L24ZZ
A postoperative patient who previously underwent partial gastrectomy develops a postoperative hemorrhage from an anastomotic arterial stump that fails endoscopic control; surgical exploration and ligation of the bleeding gastric artery branch are performed to completely close the lumen and secure hemostasis. Typical codes: 04L20CZ, 04L20ZZ
