About 0TJ50ZZ

0TJ50ZZ is the ICD-10-PCS code for a inspection procedure on the kidney using an open approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to Nephrotomy and other incision of perirenal or periureteral tissue, the ICD-9-CM procedure titles it maps to (55.01 and 59.09).

For a different body part, codes include 0TJ90ZZ (ureter), 0TJB0ZZ (bladder) and 0TJD0ZZ (urethra).

The same procedure with a different approach is coded 0TJ53ZZ (percutaneous), 0TJ54ZZ (percutaneous endoscopic), 0TJ57ZZ (via natural or artificial opening), 0TJ58ZZ (via natural or artificial opening endoscopic) and 0TJ5XZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 656 (Kidney and Ureter Procedures for Neoplasm with MCC), DRG 657 (Kidney and Ureter Procedures for Neoplasm with CC), DRG 658 (Kidney and Ureter Procedures for Neoplasm without CC/MCC), DRG 659 (Kidney and Ureter Procedures for Non-Neoplasm with MCC), DRG 660 (Kidney and Ureter Procedures for Non-Neoplasm with CC) and DRG 661 (Kidney and Ureter Procedures for Non-Neoplasm without CC/MCC), under the surgical categories “”, “Kidney and Ureter Procedures for Non-Neoplasm” and “Other O.R. Procedures for Injuries”.
