About DW021ZZ
DW021ZZ is the ICD-10-PCS code for a beam radiation procedure on the chest using a photons 1 - 10 mev approach with none (qualifier: none).
In plain terms, this corresponds to teleradiotherapy using photons, the ICD-9-CM procedure title it maps to (92.24).
For a different body part, codes include DW011ZZ (head and neck), DW031ZZ (abdomen), DW041ZZ (hemibody), DW051ZZ (whole body) and DW061ZZ (pelvic region).
The same procedure with a different approach is coded DW020ZZ (photons <1 mev), DW022ZZ (photons >10 mev), DW023ZZ (electrons), DW024ZZ (heavy particles (protons,ions)), DW025ZZ (neutrons) and DW026ZZ (neutron capture).
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.
