About DP055ZZ
DP055ZZ is the ICD-10-PCS code for a beam radiation procedure on the rib(s) 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 DP005ZZ (skull), DP025ZZ (maxilla), DP035ZZ (mandible), DP045ZZ (sternum), DP065ZZ (humerus), DP075ZZ (radius/ulna) and 4 more.
The same procedure with a different approach is coded DP050ZZ (photons <1 mev), DP051ZZ (photons 1 - 10 mev), DP052ZZ (photons >10 mev), DP053ZZ (electrons), DP054ZZ (heavy particles (protons,ions)) and DP056ZZ (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.
