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 0495 includes procedures performed to drain fluids or gases from arterial structures in the superior mesenteric artery. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs a drainage procedure on the superior mesenteric artery to remove blood, thrombus, embolus, or infectious material causing compromise. Accurate coding within the ICD-10-PCS 0495 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Superior Mesenteric Artery Drainage Procedure Overview

Procedures in this group involve drainage of the superior mesenteric artery and target the lower arteries of the abdominal vasculature. These interventions remove fluids or gases from the superior mesenteric artery to relieve obstruction, infection, or hematoma. Accurate coding is important because it ensures proper inpatient documentation of vascular drainage procedures and supports appropriate reimbursement.

Typical Clinical Scenarios

An elderly patient presents to the emergency department with sudden onset severe abdominal pain, palpable abdominal tenderness, and signs of mesenteric ischemia on imaging with evidence of intraluminal thrombus within the superior mesenteric artery causing reduced perfusion. Interventional access is used emergently to evacuate thrombus and restore flow; a drainage catheter is left in place to remove residual blood product and prevent re-occlusion. An open approach with placement of a drainage device is performed because endovascular options are not feasible given vessel anatomy and clot burden. Typical codes: 049500Z
A middle-aged patient with a history of infected pseudoaneurysm of the superior mesenteric artery is admitted for planned operative management. During the scheduled procedure the surgeon performs controlled drainage of purulent material from the arterial sac to control infection prior to definitive repair; due to anticipated contaminated field and need for direct visualization an open approach without additional diagnostic intent is used. A drainage maneuver is performed to evacuate infectious material and reduce sepsis risk before reconstruction. Typical codes: 04950ZZ
A patient who underwent percutaneous thrombectomy of the superior mesenteric artery several days prior develops a persistent arterial hematoma with ongoing localized fluid collection on follow-up imaging and worsening abdominal pain. A percutaneous drainage procedure is performed under imaging guidance to aspirate the collection and a drainage catheter is left in place to allow ongoing evacuation and monitoring. The percutaneous approach with drainage device placement is selected to avoid reoperation. Typical codes: 049530Z
