About DB12BYZ

DB12BYZ is the ICD-10-PCS code for a brachytherapy procedure on the lung 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 DB10BYZ (trachea), DB11BYZ (bronchus), DB15BYZ (pleura), DB16BYZ (mediastinum), DB17BYZ (chest wall) and DB18BYZ (diaphragm).

The same procedure with a different approach is coded DB129YZ (high dose rate (HDR)).

With a different device, use DB12B6Z (cesium 131 (cs-131)), DB12B7Z (cesium 137 (cs-137)), DB12B8Z (iridium 192 (ir-192)), DB12B9Z (iodine 125 (I-125)), DB12BBZ (palladium 103 (pd-103)) and DB12BCZ (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.
