About DF020ZZ
DF020ZZ is the ICD-10-PCS code for a beam radiation procedure on the bile ducts using a photons <1 mev approach with none (qualifier: none).
In plain terms, this corresponds to Orthovoltage radiation and teleradiotherapy using photons, the ICD-9-CM procedure titles it maps to (92.22 and 92.24).
For a different body part, codes include DF000ZZ (liver), DF010ZZ (gallbladder) and DF030ZZ (pancreas).
The same procedure with a different approach is coded DF021ZZ (photons 1 - 10 mev), DF022ZZ (photons >10 mev), DF023ZZ (electrons), DF024ZZ (heavy particles (protons,ions)), DF025ZZ (neutrons) and DF026ZZ (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.
