About 0TW57YZ

0TW57YZ is the ICD-10-PCS code for a revision procedure on the kidney using a via natural or artificial opening 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 Nephrotomy, the ICD-9-CM procedure title it maps to (55.01).

For a different body part, codes include 0TW97YZ (ureter), 0TWB7YZ (bladder) and 0TWD7YZ (urethra).

The same procedure with a different approach is coded 0TW50YZ (open), 0TW53YZ (percutaneous), 0TW54YZ (percutaneous endoscopic) and 0TW58YZ (via natural or artificial opening endoscopic).

With a different device, use 0TW570Z (drainage device), 0TW572Z (monitoring device), 0TW573Z (infusion device), 0TW577Z (autologous tissue substitute), 0TW57CZ (extraluminal device), 0TW57DZ (intraluminal device) and 2 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.
