About 0DN40ZZ

0DN40ZZ is the ICD-10-PCS code for a release procedure on the esophagogastric junction using an open 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 esophagus, the ICD-9-CM procedure title it maps to (42.89).

For a different body part, codes include 0DN10ZZ (esophagus, upper), 0DN20ZZ (esophagus, middle), 0DN30ZZ (esophagus, lower), 0DN50ZZ (esophagus), 0DN60ZZ (stomach), 0DN70ZZ (stomach, pylorus) and 20 more.

The same procedure with a different approach is coded 0DN43ZZ (percutaneous), 0DN44ZZ (percutaneous endoscopic), 0DN47ZZ (via natural or artificial opening) and 0DN48ZZ (via natural or artificial opening endoscopic).

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), DRG 328 (Stomach, Esophageal and Duodenal Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Stomach, Esophageal and Duodenal Procedures” and “Other O.R. Procedures for Injuries”.

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