About 0DNQ3ZZ

0DNQ3ZZ is the ICD-10-PCS code for a release procedure on the anus using a percutaneous approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to incision of anal septum, the ICD-9-CM procedure title it maps to (49.91).

For a different body part, codes include 0DN13ZZ (esophagus, upper), 0DN23ZZ (esophagus, middle), 0DN33ZZ (esophagus, lower), 0DN43ZZ (esophagogastric junction), 0DN53ZZ (esophagus), 0DN63ZZ (stomach) and 20 more.

The same procedure with a different approach is coded 0DNQ0ZZ (open), 0DNQ4ZZ (percutaneous endoscopic), 0DNQ7ZZ (via natural or artificial opening), 0DNQ8ZZ (via natural or artificial opening endoscopic) and 0DNQXZZ (external).

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.
