About DF1098Z

DF1098Z is the ICD-10-PCS code for a brachytherapy procedure on the liver using a high dose rate (HDR) approach with iridium 192 (ir-192) (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 DF1198Z (gallbladder), DF1298Z (bile ducts) and DF1398Z (pancreas).

The same procedure with a different approach is coded DF10B8Z (low dose rate (LDR)).

With a different device, use DF1097Z (cesium 137 (cs-137)), DF1099Z (iodine 125 (I-125)), DF109BZ (palladium 103 (pd-103)), DF109CZ (californium 252 (cf-252)) 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.
