About 0TH90MZ

0TH90MZ is the ICD-10-PCS code for a insertion procedure on the ureter using an open approach with stimulator lead. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.

In plain terms, this corresponds to implantation of electronic ureteral stimulator, the ICD-9-CM procedure title it maps to (56.92).

For a different body part, codes include 0THB0MZ (bladder).

The same procedure with a different approach is coded 0TH93MZ (percutaneous), 0TH94MZ (percutaneous endoscopic), 0TH97MZ (via natural or artificial opening) and 0TH98MZ (via natural or artificial opening endoscopic).

With a different device, use 0TH901Z (radioactive element), 0TH902Z (monitoring device), 0TH903Z (infusion device) and 0TH90YZ (other 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 “” and “Kidney and Ureter Procedures for Non-Neoplasm”.

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