About 0DNJ7ZZ

0DNJ7ZZ is the ICD-10-PCS code for a release procedure on the appendix using a via natural or artificial opening 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 operations on appendix, the ICD-9-CM procedure title it maps to (47.99).

For a different body part, codes include 0DN17ZZ (esophagus, upper), 0DN27ZZ (esophagus, middle), 0DN37ZZ (esophagus, lower), 0DN47ZZ (esophagogastric junction), 0DN57ZZ (esophagus), 0DN67ZZ (stomach) and 16 more.

The same procedure with a different approach is coded 0DNJ0ZZ (open), 0DNJ3ZZ (percutaneous), 0DNJ4ZZ (percutaneous endoscopic) and 0DNJ8ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 397 (Appendix Procedures with MCC), DRG 398 (Appendix Procedures with CC) and DRG 399 (Appendix Procedures without CC/MCC), under the surgical category “Appendix Procedures”.

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