About 0Y9540Z

0Y9540Z is the ICD-10-PCS code for a drainage procedure on the right inguinal region 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 abdominal wall, the ICD-9-CM procedure title it maps to (54.0).

The same procedure with a different approach is coded 0Y9500Z (open) and 0Y9530Z (percutaneous).

With a different device, use 0Y954ZZ (no device).
