About 0TWB43Z

0TWB43Z is the ICD-10-PCS code for a revision procedure on the bladder using a percutaneous endoscopic approach with infusion device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

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 0TW543Z (kidney), 0TW943Z (ureter) and 0TWD43Z (urethra).

The same procedure with a different approach is coded 0TWB03Z (open), 0TWB33Z (percutaneous), 0TWB73Z (via natural or artificial opening), 0TWB83Z (via natural or artificial opening endoscopic) and 0TWBX3Z (external).

With a different device, use 0TWB40Z (drainage device), 0TWB42Z (monitoring device), 0TWB47Z (autologous tissue substitute), 0TWB4CZ (extraluminal device), 0TWB4DZ (intraluminal device), 0TWB4JZ (synthetic substitute) and 4 more.

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. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Minor Bladder Procedures” and “Other O.R. Procedures for Injuries”.

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