About 0TW50KZ

0TW50KZ is the ICD-10-PCS code for a revision procedure on the kidney using an open approach with nonautologous tissue substitute. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to Nephrotomy, the ICD-9-CM procedure title it maps to (55.01).

For a different body part, codes include 0TW90KZ (ureter), 0TWB0KZ (bladder) and 0TWD0KZ (urethra).

The same procedure with a different approach is coded 0TW53KZ (percutaneous), 0TW54KZ (percutaneous endoscopic), 0TW57KZ (via natural or artificial opening), 0TW58KZ (via natural or artificial opening endoscopic) and 0TW5XKZ (external).

With a different device, use 0TW500Z (drainage device), 0TW502Z (monitoring device), 0TW503Z (infusion device), 0TW507Z (autologous tissue substitute), 0TW50CZ (extraluminal device), 0TW50DZ (intraluminal device) and 2 more.

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” and “Other O.R. Procedures for Injuries”.

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