About 0T8C4ZZ

0T8C4ZZ is the ICD-10-PCS code for a division procedure on the bladder neck using a percutaneous endoscopic approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.

In plain terms, this corresponds to sphincterotomy of bladder, the ICD-9-CM procedure title it maps to (57.91).

For a different body part, codes include 0T824ZZ (bilateral kidneys).

The same procedure with a different approach is coded 0T8C0ZZ (open) and 0T8C3ZZ (percutaneous).

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.
