About 0TW50YZ

0TW50YZ is the ICD-10-PCS code for a revision procedure on the kidney using an open approach with other device. 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 0TW90YZ (ureter), 0TWB0YZ (bladder) and 0TWD0YZ (urethra).

The same procedure with a different approach is coded 0TW53YZ (percutaneous), 0TW54YZ (percutaneous endoscopic), 0TW57YZ (via natural or artificial opening) and 0TW58YZ (via natural or artificial opening endoscopic).

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.
