About DB066ZZ

DB066ZZ is the ICD-10-PCS code for a beam radiation procedure on the mediastinum using a neutron capture 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 DB006ZZ (trachea), DB016ZZ (bronchus), DB026ZZ (lung), DB056ZZ (pleura), DB076ZZ (chest wall) and DB086ZZ (diaphragm).

The same procedure with a different approach is coded DB060ZZ (photons <1 mev), DB061ZZ (photons 1 - 10 mev), DB062ZZ (photons >10 mev), DB063ZZ (electrons), DB064ZZ (heavy particles (protons,ions)) and DB065ZZ (neutrons).

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.
