About 0TW577Z

0TW577Z is the ICD-10-PCS code for a revision procedure on the kidney using a via natural or artificial opening approach with autologous 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 0TW977Z (ureter), 0TWB77Z (bladder) and 0TWD77Z (urethra).

The same procedure with a different approach is coded 0TW507Z (open), 0TW537Z (percutaneous), 0TW547Z (percutaneous endoscopic), 0TW587Z (via natural or artificial opening endoscopic) and 0TW5X7Z (external).

With a different device, use 0TW570Z (drainage device), 0TW572Z (monitoring device), 0TW573Z (infusion device), 0TW57CZ (extraluminal device), 0TW57DZ (intraluminal device), 0TW57JZ (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.
