About 0D994ZZ

0D994ZZ is the ICD-10-PCS code for a drainage procedure on the duodenum using a percutaneous endoscopic approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to incision of duodenum, the ICD-9-CM procedure title it maps to (45.01).
