CPT® Code 77523

The CPT® Code 77523 refers to the delivery of proton treatment, specifically categorized as intermediate. This procedure involves the administration of radiation therapy using a proton beam, which is a type of particle therapy that utilizes protons to target tumors. The precision of proton therapy allows for the effective treatment of tumors that are situated deep within the body, often surrounded by significant amounts of healthy tissue. By focusing the proton beam directly on the tumor, the risk of damaging adjacent healthy tissues is minimized, making it a preferred option for certain types of cancers. The procedure is characterized by its delivery to two or more treatment areas, which may involve the use of two or more ports or a combination of tangential and oblique ports. Additionally, custom blocks and compensators are employed to enhance the accuracy and effectiveness of the treatment, ensuring that the proton beam conforms to the shape of the tumor while sparing surrounding healthy structures.
