About 0TW94YZ

0TW94YZ is the ICD-10-PCS code for a revision procedure on the ureter using a percutaneous endoscopic approach with other device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to Ureterotomy, the ICD-9-CM procedure title it maps to (56.2).

For a different body part, codes include 0TW54YZ (kidney), 0TWB4YZ (bladder) and 0TWD4YZ (urethra).

The same procedure with a different approach is coded 0TW90YZ (open), 0TW93YZ (percutaneous), 0TW97YZ (via natural or artificial opening) and 0TW98YZ (via natural or artificial opening endoscopic).

With a different device, use 0TW940Z (drainage device), 0TW942Z (monitoring device), 0TW943Z (infusion device), 0TW947Z (autologous tissue substitute), 0TW94CZ (extraluminal device), 0TW94DZ (intraluminal device) and 3 more.

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
