About 0T9770Z

0T9770Z is the ICD-10-PCS code for a drainage procedure on the left ureter using a via natural or artificial opening approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to ureteral catheterization, the ICD-9-CM procedure title it maps to (59.8).

For a different body part, codes include 0T9070Z (right kidney), 0T9170Z (left kidney), 0T9370Z (right kidney pelvis), 0T9470Z (left kidney pelvis), 0T9670Z (right ureter), 0T9870Z (bilateral ureters) and 3 more.

The same procedure with a different approach is coded 0T9700Z (open), 0T9730Z (percutaneous), 0T9740Z (percutaneous endoscopic) and 0T9780Z (via natural or artificial opening endoscopic).

With a different device, use 0T977ZZ (no device).

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.
