About 04SY4ZZ

04SY4ZZ is the ICD-10-PCS code for a reposition procedure on the lower artery using a percutaneous endoscopic approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to other repair of vessel, the ICD-9-CM procedure title it maps to (39.59).

For a different body part, codes include 04S04ZZ (abdominal aorta), 04S14ZZ (celiac artery), 04S24ZZ (gastric artery), 04S34ZZ (hepatic artery), 04S44ZZ (splenic artery), 04S54ZZ (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04SY0ZZ (open) and 04SY3ZZ (percutaneous).

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 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Other Vascular Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Other O.R.
