About 0TH903Z

0TH903Z is the ICD-10-PCS code for a insertion procedure on the ureter using an open 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 0TH503Z (kidney), 0THB03Z (bladder) and 0THD03Z (urethra).

The same procedure with a different approach is coded 0TH933Z (percutaneous), 0TH943Z (percutaneous endoscopic), 0TH973Z (via natural or artificial opening) and 0TH983Z (via natural or artificial opening endoscopic).

With a different device, use 0TH901Z (radioactive element), 0TH902Z (monitoring device), 0TH90MZ (stimulator lead) and 0TH90YZ (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.
