About 0W3C4ZZ

0W3C4ZZ is the ICD-10-PCS code for a control procedure on the mediastinum using a percutaneous endoscopic approach. In ICD-10-PCS, control means stopping, or attempting to stop, postprocedural or other acute bleeding.

In plain terms, this corresponds to control of hemorrhage following vascular surgery, the ICD-9-CM procedure title it maps to (39.41).

For a different body part, codes include 0W304ZZ (head), 0W314ZZ (cranial cavity), 0W324ZZ (face), 0W334ZZ (oral cavity and throat), 0W344ZZ (upper jaw), 0W354ZZ (lower jaw) and 16 more.

The same procedure with a different approach is coded 0W3C0ZZ (open) and 0W3C3ZZ (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 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.
