About 0D844ZZ

0D844ZZ is the ICD-10-PCS code for a division procedure on the esophagogastric junction using a percutaneous endoscopic approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.

In plain terms, this corresponds to other incision of esophagus and Esophagomyotomy, the ICD-9-CM procedure titles it maps to (42.09 and 42.7).

For a different body part, codes include 0D874ZZ (stomach, pylorus).

The same procedure with a different approach is coded 0D840ZZ (open), 0D843ZZ (percutaneous), 0D847ZZ (via natural or artificial opening) and 0D848ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), 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 categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Stomach, Esophageal and Duodenal Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.

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