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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0616 includes procedures performed to bypass venous structures in the inferior mesenteric vein. These ICD-10-PCS codes are used for inpatient documentation when a bypass is performed to reroute venous flow around an obstruction or damaged segment of the inferior mesenteric vein. Accurate coding within the ICD-10-PCS 0616 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Inferior Mesenteric Vein Bypass Procedure Overview

Procedures in this group involve creating an alternate pathway to alter the route of venous blood flow in the inferior mesenteric vein, which is part of the lower veins system. These bypass operations reroute blood around an obstruction or damaged segment of the vein to restore or improve venous drainage. Accurate ICD-10-PCS coding of these procedures supports appropriate inpatient reimbursement and reflects the clinical complexity of vascular interventions.

When to Use

Use a code from this group when an operative bypass of the inferior mesenteric vein is performed to reroute venous blood flow. This includes situations where the vein is obstructed, thrombosed, or otherwise compromised and an alternate venous route is created.

Typical Clinical Scenarios

An adult patient presents emergently with acute mesenteric venous thrombosis causing progressive congestion of the distal colon and signs of venous outflow obstruction. Imaging demonstrates an obstructing thrombus in the inferior mesenteric vein not amenable to endovascular thrombectomy alone, and intraoperative decision is made to create an open bypass using an autologous venous graft to restore venous drainage. The procedure is performed via open abdominal approach to reroute flow around the thrombosed segment. Typical codes: 061609Y
A patient with chronic mesenteric venous stenosis causing progressive lower bowel edema and recurrent abdominal pain is scheduled electively for surgical reconstruction. Preoperative planning determines an open bypass from the inferior mesenteric vein to a patent lower vein using a synthetic conduit to bypass the fibrotic segment and improve long-term venous drainage. The elective open operation aims to relieve symptoms and prevent further ischemic complications. Typical codes: 06160JY
A patient with previous inferior mesenteric vein repair presents with recurrent obstruction at the repair site due to graft failure and scarring, with worsening venous hypertension and ischemic symptoms. During reoperation a percutaneous endoscopic-assisted bypass is performed using an autologous tissue substitute harvested at the time of surgery to reestablish venous outflow around the failed repair. The minimally invasive approach is chosen to limit additional open dissection in a reoperative field. Typical codes: 061647Y
