About DB16B6Z
DB16B6Z is the ICD-10-PCS code for a brachytherapy procedure on the mediastinum using a low dose rate (LDR) approach with cesium 131 (cs-131) (qualifier: none).
For a different body part, codes include DB10B6Z (trachea), DB11B6Z (bronchus), DB12B6Z (lung), DB15B6Z (pleura), DB17B6Z (chest wall) and DB18B6Z (diaphragm).
With a different device, use DB16B7Z (cesium 137 (cs-137)), DB16B8Z (iridium 192 (ir-192)), DB16B9Z (iodine 125 (I-125)), DB16BBZ (palladium 103 (pd-103)), DB16BCZ (californium 252 (cf-252)) and DB16BYZ (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.
