About DG10BYZ

DG10BYZ is the ICD-10-PCS code for a brachytherapy procedure on the pituitary gland 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 DG11BYZ (pineal body), DG12BYZ (adrenal glands), DG14BYZ (parathyroid glands) and DG15BYZ (thyroid).

The same procedure with a different approach is coded DG109YZ (high dose rate (HDR)).

With a different device, use DG10B6Z (cesium 131 (cs-131)), DG10B7Z (cesium 137 (cs-137)), DG10B8Z (iridium 192 (ir-192)), DG10B9Z (iodine 125 (I-125)), DG10BBZ (palladium 103 (pd-103)) and DG10BCZ (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.
