About 0W9J40Z

0W9J40Z is the ICD-10-PCS code for a drainage procedure on the pelvic cavity using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to incision of peritoneum, the ICD-9-CM procedure title it maps to (54.95).

For a different body part, codes include 0W9040Z (head), 0W9140Z (cranial cavity), 0W9240Z (face), 0W9340Z (oral cavity and throat), 0W9440Z (upper jaw), 0W9540Z (lower jaw) and 13 more.

The same procedure with a different approach is coded 0W9J00Z (open), 0W9J30Z (percutaneous), 0W9J70Z (via natural or artificial opening) and 0W9J80Z (via natural or artificial opening endoscopic).

With a different device, use 0W9J4ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC) and DRG 356 (Other Digestive System O.R. Procedures with MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Circulatory System O.R. Procedures”, “Other Digestive System O.R. Procedures” and 3 more.

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