About DG15B6Z
DG15B6Z is the ICD-10-PCS code for a brachytherapy procedure on the thyroid using a low dose rate (LDR) approach with cesium 131 (cs-131) (qualifier: none).
For a different body part, codes include DG10B6Z (pituitary gland), DG11B6Z (pineal body), DG12B6Z (adrenal glands) and DG14B6Z (parathyroid glands).
With a different device, use DG15B7Z (cesium 137 (cs-137)), DG15B8Z (iridium 192 (ir-192)), DG15B9Z (iodine 125 (I-125)), DG15BBZ (palladium 103 (pd-103)), DG15BCZ (californium 252 (cf-252)) and DG15BYZ (other isotope).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It was added in FY2021, effective October 1, 2020.
