About D010BYZ

D010BYZ is the ICD-10-PCS code for a brachytherapy procedure on the brain using a low dose rate (LDR) approach with other isotope (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 D011BYZ (brain stem), D016BYZ (spinal cord) and D017BYZ (peripheral nerve).

The same procedure with a different approach is coded D0109YZ (high dose rate (HDR)).

With a different device, use D010B6Z (cesium 131 (cs-131)), D010B7Z (cesium 137 (cs-137)), D010B8Z (iridium 192 (ir-192)), D010B9Z (iodine 125 (I-125)), D010BBZ (palladium 103 (pd-103)) and D010BCZ (californium 252 (cf-252)).

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.
