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 04H2 includes procedures performed to insert monitoring or similar devices in the gastric artery of the lower arteries. These ICD-10-PCS codes are used for inpatient documentation when a device is placed into the gastric artery to monitor or otherwise support vascular physiological function. Accurate coding within the ICD-10-PCS 04H2 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Gastric Artery Insertion Procedure Overview

This group includes procedures that involve insertion of nonbiological appliances into the gastric artery to monitor, assist, perform, or prevent physiological functions of the lower arteries. These procedures target the lower arteries of the gastrointestinal circulation and require precise documentation of device type and vascular location. Accurate coding is important for inpatient reimbursement because it captures the specific vascular insertion performed and supports correct case mix and payment.

Typical Clinical Scenarios

An unstable postoperative patient after partial gastrectomy develops sudden unexplained gastrointestinal bleeding with hemodynamic compromise; interventional vascular access to the gastric artery is required for direct monitoring of arterial flow and delivery of vasoconstrictive agents while coordinating resuscitation. A device is inserted into the gastric artery via an open surgical field when percutaneous access is not feasible due to recent abdominal surgery or contamination. Typical codes: 04H203Z, 04H20DZ
An elective preoperative procedure for a patient with chronic mesenteric ischemia scheduled for complex gastric arterial reconstruction; intra-arterial monitoring is planned to provide continuous arterial pressure and allow targeted intra-arterial infusion of vasodilators during the operation. The device is placed percutaneously under fluoroscopic guidance into the gastric artery before the reconstructive procedure to optimize hemodynamic management. Typical codes: 04H233Z, 04H23DZ
A patient with a previously placed gastric artery monitoring catheter presents with signs of catheter malfunction and recurrent ischemic symptoms; the inpatient team performs a revision, removing the failed intraluminal device and replacing it using a percutaneous endoscopic approach to restore monitoring and intravascular therapy capability. Typical codes: 04H243Z, 04H24DZ
