About 0TU477Z

0TU477Z is the ICD-10-PCS code for a supplement procedure on the left kidney pelvis using a via natural or artificial opening approach with autologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

In plain terms, this corresponds to other repair of kidney, the ICD-9-CM procedure title it maps to (55.89).

For a different body part, codes include 0TU377Z (right kidney pelvis), 0TU677Z (right ureter), 0TU777Z (left ureter), 0TUB77Z (bladder), 0TUC77Z (bladder neck) and 0TUD77Z (urethra).

The same procedure with a different approach is coded 0TU407Z (open), 0TU447Z (percutaneous endoscopic) and 0TU487Z (via natural or artificial opening endoscopic).

With a different device, use 0TU47JZ (synthetic substitute) and 0TU47KZ (nonautologous tissue substitute).

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 “” and “Kidney and Ureter Procedures for Non-Neoplasm”.

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