About 0T18477

0T18477 is the ICD-10-PCS code for a bypass procedure on the bilateral ureters using a percutaneous endoscopic approach with autologous tissue substitute (qualifier: left ureter). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

In plain terms, this corresponds to Transureteroureterostomy, the ICD-9-CM procedure title it maps to (56.75).

For a different body part, codes include 0T13477 (right kidney pelvis), 0T14477 (left kidney pelvis), 0T16477 (right ureter) and 0T17477 (left ureter).

The same procedure with a different approach is coded 0T18077 (open).

With a different device, use 0T184J7 (synthetic substitute), 0T184K7 (nonautologous tissue substitute) and 0T184Z7 (no device).

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”, “Other Male Reproductive System O.R. Procedures” and 5 more.

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