About 0DNK7ZZ

0DNK7ZZ is the ICD-10-PCS code for a release procedure on the ascending colon 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 dilation and manipulation of enterostomy stoma, the ICD-9-CM procedure title it maps to (96.24).

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 0DNK0ZZ (open), 0DNK3ZZ (percutaneous), 0DNK4ZZ (percutaneous endoscopic) and 0DNK8ZZ (via natural or artificial opening endoscopic).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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