About 0DTQ0ZZ

0DTQ0ZZ is the ICD-10-PCS code for a resection procedure on the anus using an open 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 0DT10ZZ (esophagus, upper), 0DT20ZZ (esophagus, middle), 0DT30ZZ (esophagus, lower), 0DT40ZZ (esophagogastric junction), 0DT50ZZ (esophagus), 0DT60ZZ (stomach) and 18 more.

The same procedure with a different approach is coded 0DTQ4ZZ (percutaneous endoscopic), 0DTQ7ZZ (via natural or artificial opening) and 0DTQ8ZZ (via natural or artificial opening endoscopic).

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.
