About DG1199Z

DG1199Z is the ICD-10-PCS code for a brachytherapy procedure on the pineal body 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 DG1099Z (pituitary gland), DG1299Z (adrenal glands), DG1499Z (parathyroid glands) and DG1599Z (thyroid).

The same procedure with a different approach is coded DG11B9Z (low dose rate (LDR)).

With a different device, use DG1197Z (cesium 137 (cs-137)), DG1198Z (iridium 192 (ir-192)), DG119BZ (palladium 103 (pd-103)), DG119CZ (californium 252 (cf-252)) and DG119YZ (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.
