About 0U9900Z

0U9900Z is the ICD-10-PCS code for a drainage procedure on the uterus using an open approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to Hysterotomy, the ICD-9-CM procedure title it maps to (68.0).
