About DWY5GDZ
DWY5GDZ is the ICD-10-PCS code for a other radiation procedure on the whole body using an isotope administration approach with iodine 131 (I-131) (qualifier: none).
In plain terms, this corresponds to injection or instillation of radioisotopes, the ICD-9-CM procedure title it maps to (92.28).
With a different device, use DWY5GFZ (phosphorus 32 (P-32)), DWY5GGZ (strontium 89 (sr-89)), DWY5GHZ (strontium 90 (sr-90)) and DWY5GYZ (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.
