About 0DN78ZZ

0DN78ZZ is the ICD-10-PCS code for a release procedure on the stomach, pylorus using a via natural or artificial opening 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 pyloroplasty, the ICD-9-CM procedure title it maps to (44.29).

For a different body part, codes include 0DN18ZZ (esophagus, upper), 0DN28ZZ (esophagus, middle), 0DN38ZZ (esophagus, lower), 0DN48ZZ (esophagogastric junction), 0DN58ZZ (esophagus), 0DN68ZZ (stomach) and 16 more.

The same procedure with a different approach is coded 0DN70ZZ (open), 0DN73ZZ (percutaneous), 0DN74ZZ (percutaneous endoscopic) and 0DN77ZZ (via natural or artificial opening).

It is an operating-room procedure in the MS-DRG logic for DRG 326 (Stomach, Esophageal and Duodenal Procedures with MCC), DRG 327 (Stomach, Esophageal and Duodenal Procedures with CC) and DRG 328 (Stomach, Esophageal and Duodenal Procedures without CC/MCC), under the surgical category “Stomach, Esophageal and Duodenal Procedures”.

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