About 0T978ZX

0T978ZX is the ICD-10-PCS code for a drainage procedure on the left ureter using a via natural or artificial opening 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 endoscopic biopsy of ureter, the ICD-9-CM procedure title it maps to (56.33).

For a different body part, codes include 0T908ZX (right kidney), 0T918ZX (left kidney), 0T938ZX (right kidney pelvis), 0T948ZX (left kidney pelvis), 0T968ZX (right ureter), 0T988ZX (bilateral ureters) and 3 more.

The same procedure with a different approach is coded 0T970ZX (open), 0T973ZX (percutaneous), 0T974ZX (percutaneous endoscopic) and 0T977ZX (via natural or artificial opening).

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.
