About 04CS0ZZ

04CS0ZZ is the ICD-10-PCS code for a extirpation procedure on the left posterior tibial 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, lower limb arteries and Endarterectomy, lower limb arteries, the ICD-9-CM procedure titles it maps to (00.40, 38.08 and 38.18).

The same procedure with a different approach is coded 04CS3ZZ (percutaneous) and 04CS4ZZ (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.
