About 0T788ZZ

0T788ZZ is the ICD-10-PCS code for a dilation procedure on the bilateral ureters using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to dilation of ureteral meatus, the ICD-9-CM procedure title it maps to (56.91).

For a different body part, codes include 0T738ZZ (right kidney pelvis), 0T748ZZ (left kidney pelvis), 0T768ZZ (right ureter), 0T778ZZ (left ureter), 0T7B8ZZ (bladder), 0T7C8ZZ (bladder neck) and 1 more.

The same procedure with a different approach is coded 0T780ZZ (open), 0T783ZZ (percutaneous), 0T784ZZ (percutaneous endoscopic) and 0T787ZZ (via natural or artificial opening).

With a different device, use 0T788DZ (intraluminal 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.
