About 0THB4YZ

0THB4YZ is the ICD-10-PCS code for a insertion procedure on the bladder using a percutaneous endoscopic approach with other 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 cystotomy, the ICD-9-CM procedure title it maps to (57.19).

For a different body part, codes include 0TH54YZ (kidney), 0TH94YZ (ureter) and 0THD4YZ (urethra).

The same procedure with a different approach is coded 0THB0YZ (open), 0THB3YZ (percutaneous), 0THB7YZ (via natural or artificial opening) and 0THB8YZ (via natural or artificial opening endoscopic).

With a different device, use 0THB41Z (radioactive element), 0THB42Z (monitoring device), 0THB43Z (infusion device), 0THB4LZ (artificial sphincter) and 0THB4MZ (stimulator lead).

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

It was added in FY2018, effective October 1, 2017.
