About 0DWR4MZ

0DWR4MZ is the ICD-10-PCS code for a revision procedure on the anal sphincter using a percutaneous endoscopic approach with stimulator lead. 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 other incision of anus, the ICD-9-CM procedure title it maps to (49.93).

For a different body part, codes include 0DW64MZ (stomach).

The same procedure with a different approach is coded 0DWR0MZ (open) and 0DWR3MZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 347 (Anal and Stomal Procedures with MCC), DRG 348 (Anal and Stomal Procedures with CC) and DRG 349 (Anal and Stomal Procedures without CC/MCC), under the surgical category “Anal and Stomal Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
