About 0DNR4ZZ

0DNR4ZZ is the ICD-10-PCS code for a release procedure on the anal sphincter using a percutaneous endoscopic 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 other repair of anal sphincter, the ICD-9-CM procedure title it maps to (49.79).

For a different body part, codes include 0DN14ZZ (esophagus, upper), 0DN24ZZ (esophagus, middle), 0DN34ZZ (esophagus, lower), 0DN44ZZ (esophagogastric junction), 0DN54ZZ (esophagus), 0DN64ZZ (stomach) and 20 more.

The same procedure with a different approach is coded 0DNR0ZZ (open) and 0DNR3ZZ (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), DRG 349 (Anal and Stomal Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Anal and Stomal Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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