About DF109CZ
DF109CZ is the ICD-10-PCS code for a brachytherapy procedure on the liver using a high dose rate (HDR) approach with californium 252 (cf-252) (qualifier: none).
In plain terms, this corresponds to Radioisotopic teleradiotherapy, the ICD-9-CM procedure title it maps to (92.23).
For a different body part, codes include DF119CZ (gallbladder), DF129CZ (bile ducts) and DF139CZ (pancreas).
The same procedure with a different approach is coded DF10BCZ (low dose rate (LDR)).
With a different device, use DF1097Z (cesium 137 (cs-137)), DF1098Z (iridium 192 (ir-192)), DF1099Z (iodine 125 (I-125)), DF109BZ (palladium 103 (pd-103)) and DF109YZ (other isotope).
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.
