About 0TW970Z

0TW970Z is the ICD-10-PCS code for a revision procedure on the ureter using a via natural or artificial opening approach with drainage 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 Ureterotomy, the ICD-9-CM procedure title it maps to (56.2).

For a different body part, codes include 0TW570Z (kidney), 0TWB70Z (bladder) and 0TWD70Z (urethra).

The same procedure with a different approach is coded 0TW900Z (open), 0TW930Z (percutaneous), 0TW940Z (percutaneous endoscopic), 0TW980Z (via natural or artificial opening endoscopic) and 0TW9X0Z (external).

With a different device, use 0TW972Z (monitoring device), 0TW973Z (infusion device), 0TW977Z (autologous tissue substitute), 0TW97CZ (extraluminal device), 0TW97DZ (intraluminal device), 0TW97JZ (synthetic substitute) and 3 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 “” and “Kidney and Ureter Procedures for Non-Neoplasm”.

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