About 0YJ50ZZ

0YJ50ZZ is the ICD-10-PCS code for a inspection procedure on the right inguinal region using an open approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to incision of abdominal wall, the ICD-9-CM procedure title it maps to (54.0).

The same procedure with a different approach is coded 0YJ53ZZ (percutaneous), 0YJ54ZZ (percutaneous endoscopic) and 0YJ5XZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC), DRG 356 (Other Digestive System O.R. Procedures with MCC), DRG 357 (Other Digestive System O.R. Procedures with CC), DRG 358 (Other Digestive System O.R.
