Proton Beam Radiation Treatment Session

Montana rates for HCPCS 77522

A session of proton beam radiation therapy, in which charged particles rather than ordinary X-rays are aimed at a tumor. Protons release most of their energy at a set depth and then stop, so less radiation passes into healthy tissue beyond the target. This covers the delivery of one treatment session, not the planning that comes before the course.
