About DW11B8Z
DW11B8Z is the ICD-10-PCS code for a brachytherapy procedure on the head and neck using a low dose rate (LDR) approach with iridium 192 (ir-192) (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 DW12B8Z (chest), DW13B8Z (abdomen) and DW16B8Z (pelvic region).
The same procedure with a different approach is coded DW1198Z (high dose rate (HDR)).
With a different device, use DW11B6Z (cesium 131 (cs-131)), DW11B7Z (cesium 137 (cs-137)), 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 has been valid since ICD-10-PCS took effect on October 1, 2015.
