About 0DTR4ZZ

0DTR4ZZ is the ICD-10-PCS code for a resection procedure on the anal sphincter using a percutaneous endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to excision of anus, the ICD-9-CM procedure title it maps to (49.6).

For a different body part, codes include 0DT14ZZ (esophagus, upper), 0DT24ZZ (esophagus, middle), 0DT34ZZ (esophagus, lower), 0DT44ZZ (esophagogastric junction), 0DT54ZZ (esophagus), 0DT64ZZ (stomach) and 18 more.

The same procedure with a different approach is coded 0DTR0ZZ (open).

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.
