About 04U23KZ

04U23KZ is the ICD-10-PCS code for a supplement procedure on the gastric artery using a percutaneous approach with nonautologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

In plain terms, this corresponds to repair of blood vessel with unspecified type of patch graft, the ICD-9-CM procedure title it maps to (39.58).

For a different body part, codes include 04U03KZ (abdominal aorta), 04U13KZ (celiac artery), 04U33KZ (hepatic artery), 04U43KZ (splenic artery), 04U53KZ (superior mesenteric artery), 04U63KZ (right colic artery) and 24 more.

The same procedure with a different approach is coded 04U20KZ (open) and 04U24KZ (percutaneous endoscopic).

With a different device, use 04U237Z (autologous tissue substitute) and 04U23JZ (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
