About 0WFD4ZZ

0WFD4ZZ is the ICD-10-PCS code for a fragmentation procedure on the pericardial cavity using a percutaneous endoscopic approach. In ICD-10-PCS, fragmentation means breaking solid matter in a body part into pieces.

In plain terms, this corresponds to other repair of heart and pericardium, the ICD-9-CM procedure title it maps to (37.49).

For a different body part, codes include 0WF14ZZ (cranial cavity), 0WF34ZZ (oral cavity and throat), 0WF94ZZ (right pleural cavity), 0WFB4ZZ (left pleural cavity), 0WFC4ZZ (mediastinum), 0WFG4ZZ (peritoneal cavity) and 4 more.

The same procedure with a different approach is coded 0WFD0ZZ (open), 0WFD3ZZ (percutaneous) and 0WFDXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC), DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Major Cardiovascular Procedures” and “Other O.R. Procedures for Injuries”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
