About 0D794ZZ

0D794ZZ is the ICD-10-PCS code for a dilation procedure on the duodenum using a percutaneous endoscopic approach. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to myotomy of other parts of colon, the ICD-9-CM procedure title it maps to (46.92).

For a different body part, codes include 0D714ZZ (esophagus, upper), 0D724ZZ (esophagus, middle), 0D734ZZ (esophagus, lower), 0D744ZZ (esophagogastric junction), 0D754ZZ (esophagus), 0D764ZZ (stomach) and 15 more.

The same procedure with a different approach is coded 0D790ZZ (open), 0D793ZZ (percutaneous), 0D797ZZ (via natural or artificial opening) and 0D798ZZ (via natural or artificial opening endoscopic).

With a different device, use 0D794DZ (intraluminal device).

It is an operating-room procedure in the MS-DRG logic for DRG 329 (Major Small and Large Bowel Procedures with MCC), DRG 330 (Major Small and Large Bowel Procedures with CC) and DRG 331 (Major Small and Large Bowel Procedures without CC/MCC), under the surgical category “Major Small and Large Bowel Procedures”.

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