About DFY0CZZ
DFY0CZZ is the ICD-10-PCS code for a other radiation procedure on the liver using an intraoperative radiation therapy (IORT) approach with none (qualifier: none).
In plain terms, this corresponds to other radiotherapeutic procedure, the ICD-9-CM procedure title it maps to (92.29).
For a different body part, codes include DFY1CZZ (gallbladder), DFY2CZZ (bile ducts) and DFY3CZZ (pancreas).
The same procedure with a different approach is coded DFY07ZZ (contact radiation), DFY08ZZ (hyperthermia) and DFY0FZZ (plaque radiation).
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.
