About DW11B6Z
DW11B6Z is the ICD-10-PCS code for a brachytherapy procedure on the head and neck using a low dose rate (LDR) approach with cesium 131 (cs-131) (qualifier: none).
For a different body part, codes include DW12B6Z (chest), DW13B6Z (abdomen) and DW16B6Z (pelvic region).
With a different device, use DW11B7Z (cesium 137 (cs-137)), DW11B8Z (iridium 192 (ir-192)), DW11B9Z (iodine 125 (I-125)), DW11BBZ (palladium 103 (pd-103)), DW11BCZ (californium 252 (cf-252)) and DW11BYZ (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.
