About 0T9440Z

0T9440Z is the ICD-10-PCS code for a drainage procedure on the left kidney pelvis 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 other incision of perirenal or periureteral tissue, the ICD-9-CM procedure title it maps to (59.09).

For a different body part, codes include 0T9040Z (right kidney), 0T9140Z (left kidney), 0T9340Z (right kidney pelvis), 0T9640Z (right ureter), 0T9740Z (left ureter), 0T9840Z (bilateral ureters) and 3 more.

With a different device, use 0T944ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 656 (Kidney and Ureter Procedures for Neoplasm with MCC), DRG 657 (Kidney and Ureter Procedures for Neoplasm with CC), DRG 658 (Kidney and Ureter Procedures for Neoplasm without CC/MCC), DRG 659 (Kidney and Ureter Procedures for Non-Neoplasm with MCC), DRG 660 (Kidney and Ureter Procedures for Non-Neoplasm with CC) and DRG 661 (Kidney and Ureter Procedures for Non-Neoplasm without CC/MCC), under the surgical categories “”, “Kidney and Ureter Procedures for Non-Neoplasm”, “Other Male Reproductive System O.R.
