About 0THB4MZ

0THB4MZ is the ICD-10-PCS code for a insertion procedure on the bladder using a percutaneous endoscopic 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 bladder stimulator, the ICD-9-CM procedure title it maps to (57.96).

For a different body part, codes include 0TH94MZ (ureter).

The same procedure with a different approach is coded 0THB0MZ (open), 0THB3MZ (percutaneous), 0THB7MZ (via natural or artificial opening) and 0THB8MZ (via natural or artificial opening endoscopic).

With a different device, use 0THB41Z (radioactive element), 0THB42Z (monitoring device), 0THB43Z (infusion device), 0THB4LZ (artificial sphincter) and 0THB4YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 662 (Minor Bladder Procedures with MCC), DRG 663 (Minor Bladder Procedures with CC) and DRG 664 (Minor Bladder Procedures without CC/MCC), under the surgical category “Minor Bladder Procedures”.

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