About 0T777ZZ

0T777ZZ is the ICD-10-PCS code for a dilation procedure on the left ureter using a via natural or artificial opening approach. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to ureteral meatotomy and dilation of ureteral meatus, the ICD-9-CM procedure titles it maps to (56.1 and 56.91).

For a different body part, codes include 0T737ZZ (right kidney pelvis), 0T747ZZ (left kidney pelvis), 0T767ZZ (right ureter), 0T787ZZ (bilateral ureters), 0T7B7ZZ (bladder), 0T7C7ZZ (bladder neck) and 1 more.

The same procedure with a different approach is coded 0T770ZZ (open), 0T773ZZ (percutaneous), 0T774ZZ (percutaneous endoscopic) and 0T778ZZ (via natural or artificial opening endoscopic).

With a different device, use 0T777DZ (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.
