About 0TW50DZ
0TW50DZ is the ICD-10-PCS code for a revision procedure on the kidney using an open approach with intraluminal 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 0TW90DZ (ureter), 0TWB0DZ (bladder) and 0TWD0DZ (urethra).
The same procedure with a different approach is coded 0TW53DZ (percutaneous), 0TW54DZ (percutaneous endoscopic), 0TW57DZ (via natural or artificial opening), 0TW58DZ (via natural or artificial opening endoscopic) and 0TW5XDZ (external).
With a different device, use 0TW500Z (drainage device), 0TW502Z (monitoring device), 0TW503Z (infusion device), 0TW507Z (autologous tissue substitute), 0TW50CZ (extraluminal device), 0TW50JZ (synthetic substitute) 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.
