Proton Beam Radiation Treatment Session

Connecticut rates for HCPCS 77523

Delivers a session of radiation treatment using a beam of protons instead of ordinary X-rays. Protons give up most of their energy at a set depth, so the dose can be concentrated on the target with less carrying on into the tissue behind it. This level covers sessions needing more shaping and setup than the most straightforward ones.
