About DW015ZZ
DW015ZZ is the ICD-10-PCS code for a beam radiation procedure on the head and neck using a neutrons approach with none (qualifier: none).
In plain terms, this corresponds to teleradiotherapy of other particulate radiation, the ICD-9-CM procedure title it maps to (92.26).
For a different body part, codes include DW025ZZ (chest), DW035ZZ (abdomen), DW045ZZ (hemibody), DW055ZZ (whole body) and DW065ZZ (pelvic region).
The same procedure with a different approach is coded DW010ZZ (photons <1 mev), DW011ZZ (photons 1 - 10 mev), DW012ZZ (photons >10 mev), DW013ZZ (electrons), DW014ZZ (heavy particles (protons,ions)) and DW016ZZ (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.
