About DB189BZ

DB189BZ is the ICD-10-PCS code for a brachytherapy procedure on the diaphragm using a high dose rate (HDR) approach with palladium 103 (pd-103) (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 DB109BZ (trachea), DB119BZ (bronchus), DB129BZ (lung), DB159BZ (pleura), DB169BZ (mediastinum) and DB179BZ (chest wall).

The same procedure with a different approach is coded DB18BBZ (low dose rate (LDR)).

With a different device, use DB1897Z (cesium 137 (cs-137)), DB1898Z (iridium 192 (ir-192)), DB1899Z (iodine 125 (I-125)), DB189CZ (californium 252 (cf-252)) and DB189YZ (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.
