About 0TTC4ZZ

0TTC4ZZ is the ICD-10-PCS code for a resection procedure on the bladder neck using a percutaneous endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to partial cystectomy, the ICD-9-CM procedure title it maps to (57.6).

For a different body part, codes include 0TT04ZZ (right kidney), 0TT14ZZ (left kidney), 0TT24ZZ (bilateral kidneys), 0TT34ZZ (right kidney pelvis), 0TT44ZZ (left kidney pelvis), 0TT64ZZ (right ureter) and 3 more.

The same procedure with a different approach is coded 0TTC0ZZ (open), 0TTC7ZZ (via natural or artificial opening) and 0TTC8ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 653 (Major Bladder Procedures with MCC), DRG 654 (Major Bladder Procedures with CC), DRG 655 (Major Bladder Procedures without CC/MCC), DRG 707 (Major Male Pelvic Procedures with CC/MCC), DRG 708 (Major Male Pelvic Procedures without CC/MCC) and DRG 749 (Other Female Reproductive System O.R. Procedures with CC/MCC), under the surgical categories “Major Bladder Procedures”, “Major Male Pelvic Procedures”, “Other Female Reproductive System O.R. Procedures” and 4 more.

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