CPT® Code 77522

The CPT® Code 77522 refers to the procedure of proton treatment delivery, specifically categorized as a simple treatment with compensation. In this context, proton therapy is a form of radiation therapy that utilizes protons, which are positively charged particles, to target and destroy cancerous cells. This method is particularly advantageous for treating tumors that are situated deep within the body, as it allows for precise targeting of the tumor while minimizing exposure and potential damage to the surrounding healthy tissues. The procedure involves the administration of a proton beam directed at a specific tumor site, ensuring that the radiation dose is concentrated where it is most needed. The use of a custom block in conjunction with a single non-tangential or oblique port further enhances the accuracy of the treatment, allowing for tailored delivery of the radiation dose. This careful calibration is essential for optimizing treatment efficacy and reducing side effects associated with radiation therapy.
