About DD045ZZ
DD045ZZ is the ICD-10-PCS code for a beam radiation procedure on the ileum 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 DD005ZZ (esophagus), DD015ZZ (stomach), DD025ZZ (duodenum), DD035ZZ (jejunum), DD055ZZ (colon) and DD075ZZ (rectum).
The same procedure with a different approach is coded DD040ZZ (photons <1 mev), DD041ZZ (photons 1 - 10 mev), DD042ZZ (photons >10 mev), DD043ZZ (electrons), DD044ZZ (heavy particles (protons,ions)) and DD046ZZ (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.
