About 0T9C4ZX

0T9C4ZX is the ICD-10-PCS code for a drainage procedure on the bladder neck using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to closed [transurethral] biopsy of bladder, the ICD-9-CM procedure title it maps to (57.33).

For a different body part, codes include 0T904ZX (right kidney), 0T914ZX (left kidney), 0T934ZX (right kidney pelvis), 0T944ZX (left kidney pelvis), 0T964ZX (right ureter), 0T974ZX (left ureter) and 3 more.

The same procedure with a different approach is coded 0T9C0ZX (open), 0T9C3ZX (percutaneous), 0T9C7ZX (via natural or artificial opening) and 0T9C8ZX (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.
