About 04BU0ZZ

04BU0ZZ is the ICD-10-PCS code for a excision procedure on the left peroneal artery using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to resection of vessel with anastomosis, lower limb arteries and other excision of vessels, lower limb arteries, the ICD-9-CM procedure titles it maps to (38.38 and 38.68).

For a different body part, codes include 04B00ZZ (abdominal aorta), 04B10ZZ (celiac artery), 04B20ZZ (gastric artery), 04B30ZZ (hepatic artery), 04B40ZZ (splenic artery), 04B50ZZ (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04BU3ZZ (percutaneous) and 04BU4ZZ (percutaneous endoscopic).

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), DRG 254 (Other Vascular Procedures without CC/MCC), DRG 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC) and DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), under the surgical categories “Other Vascular Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.
