About 0TJ58ZZ

0TJ58ZZ is the ICD-10-PCS code for a inspection procedure on the kidney using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to Pyeloscopy and other diagnostic procedures on perirenal tissue, perivesical tissue, and retroperitoneum, the ICD-9-CM procedure titles it maps to (55.22 and 59.29).

For a different body part, codes include 0TJ98ZZ (ureter), 0TJB8ZZ (bladder) and 0TJD8ZZ (urethra).

The same procedure with a different approach is coded 0TJ50ZZ (open), 0TJ53ZZ (percutaneous), 0TJ54ZZ (percutaneous endoscopic), 0TJ57ZZ (via natural or artificial opening) and 0TJ5XZZ (external).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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