About 03ST0ZZ

03ST0ZZ is the ICD-10-PCS code for a reposition procedure on the left temporal artery using an open 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).

The same procedure with a different approach is coded 03ST3ZZ (percutaneous) and 03ST4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 037 (Extracranial Procedures with MCC), DRG 038 (Extracranial Procedures with CC), DRG 039 (Extracranial Procedures without CC/MCC), 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 categories “Extracranial Procedures”, “Other Vascular Procedures”, “Other O.R.
