About 0TBB4ZX

0TBB4ZX is the ICD-10-PCS code for a excision procedure on the bladder using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to closed [transurethral] biopsy of bladder and biopsy of perirenal or perivesical tissue, the ICD-9-CM procedure titles it maps to (57.33 and 59.21).

For a different body part, codes include 0TB04ZX (right kidney), 0TB14ZX (left kidney), 0TB34ZX (right kidney pelvis), 0TB44ZX (left kidney pelvis), 0TB64ZX (right ureter), 0TB74ZX (left ureter) and 2 more.

The same procedure with a different approach is coded 0TBB0ZX (open), 0TBB3ZX (percutaneous), 0TBB7ZX (via natural or artificial opening) and 0TBB8ZX (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 668 (Transurethral Procedures with MCC), DRG 669 (Transurethral Procedures with CC), DRG 670 (Transurethral Procedures without CC/MCC), DRG 715 (Male Reproductive System and Other O.R. Procedures for Malignancy with CC/MCC), DRG 716 (Male Reproductive System and Other O.R. Procedures for Malignancy without CC/MCC) and DRG 717 (Other Male Reproductive System O.R. Procedures with CC/MCC), under the surgical categories “Transurethral Procedures”, “”, “Other Male Reproductive System O.R. Procedures” and 1 more.

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