About 0TH543Z

0TH543Z is the ICD-10-PCS code for a insertion procedure on the kidney using a percutaneous endoscopic approach with infusion device. 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 other miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

For a different body part, codes include 0TH943Z (ureter), 0THB43Z (bladder) and 0THD43Z (urethra).

The same procedure with a different approach is coded 0TH503Z (open), 0TH533Z (percutaneous), 0TH573Z (via natural or artificial opening) and 0TH583Z (via natural or artificial opening endoscopic).

With a different device, use 0TH541Z (radioactive element), 0TH542Z (monitoring device) and 0TH54YZ (other device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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