Proton Beam Radiation Treatment, Simple

California rates for HCPCS 77520

Delivery of one session of proton beam radiation therapy, which uses charged particles that stop at a set depth in the body instead of passing all the way through. This is the straightforward form, aimed at a single treatment area without the custom-shaped devices used to shape the beam around more complicated targets. A full course is made up of many such sessions, usually given on weekdays over several weeks.
