About 03CS0ZZ

03CS0ZZ is the ICD-10-PCS code for a extirpation procedure on the right temporal artery using an open approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to procedure on single vessel, incision of vessel, other vessels of head and neck and Endarterectomy, other vessels of head and neck, the ICD-9-CM procedure titles it maps to (00.40, 38.02 and 38.12).

The same procedure with a different approach is coded 03CS3ZZ (percutaneous) and 03CS4ZZ (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 143 (Other Ear, Nose, Mouth and Throat O.R.
