About DB1199Z
DB1199Z is the ICD-10-PCS code for a brachytherapy procedure on the bronchus using a high dose rate (HDR) approach with iodine 125 (I-125) (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 DB1099Z (trachea), DB1299Z (lung), DB1599Z (pleura), DB1699Z (mediastinum), DB1799Z (chest wall) and DB1899Z (diaphragm).
The same procedure with a different approach is coded DB11B9Z (low dose rate (LDR)).
With a different device, use DB1197Z (cesium 137 (cs-137)), DB1198Z (iridium 192 (ir-192)), DB119BZ (palladium 103 (pd-103)), DB119CZ (californium 252 (cf-252)) and DB119YZ (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.
