About 0T7C4ZZ

0T7C4ZZ is the ICD-10-PCS code for a dilation procedure on the bladder neck using a percutaneous 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 bladder neck, the ICD-9-CM procedure title it maps to (57.92).

For a different body part, codes include 0T734ZZ (right kidney pelvis), 0T744ZZ (left kidney pelvis), 0T764ZZ (right ureter), 0T774ZZ (left ureter), 0T784ZZ (bilateral ureters), 0T7B4ZZ (bladder) and 1 more.

The same procedure with a different approach is coded 0T7C0ZZ (open), 0T7C3ZZ (percutaneous), 0T7C7ZZ (via natural or artificial opening) and 0T7C8ZZ (via natural or artificial opening endoscopic).

With a different device, use 0T7C4DZ (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.
