About 0T9B0ZZ

0T9B0ZZ is the ICD-10-PCS code for a drainage procedure on the bladder using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from 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 0T900ZZ (right kidney), 0T910ZZ (left kidney), 0T930ZZ (right kidney pelvis), 0T940ZZ (left kidney pelvis), 0T960ZZ (right ureter), 0T970ZZ (left ureter) and 3 more.

The same procedure with a different approach is coded 0T9B3ZZ (percutaneous), 0T9B4ZZ (percutaneous endoscopic), 0T9B7ZZ (via natural or artificial opening) and 0T9B8ZZ (via natural or artificial opening endoscopic).

With a different device, use 0T9B00Z (drainage 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), DRG 664 (Minor Bladder Procedures without CC/MCC), DRG 907 (Other O.R.
