About 0D798ZZ
0D798ZZ is the ICD-10-PCS code for a dilation procedure on the duodenum using a via natural or artificial opening 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 dilation of intestine and dilation and manipulation of enterostomy stoma, the ICD-9-CM procedure titles it maps to (46.85 and 96.24).
For a different body part, codes include 0D718ZZ (esophagus, upper), 0D728ZZ (esophagus, middle), 0D738ZZ (esophagus, lower), 0D748ZZ (esophagogastric junction), 0D758ZZ (esophagus), 0D768ZZ (stomach) and 15 more.
The same procedure with a different approach is coded 0D790ZZ (open), 0D793ZZ (percutaneous), 0D794ZZ (percutaneous endoscopic) and 0D797ZZ (via natural or artificial opening).
With a different device, use 0D798DZ (intraluminal device).
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.
