What is the cpt code for four separate areas with a rotational beam at MeV?

The CPT code for radiation therapy using a rotational beam, such as with a megavoltage (MeV) machine, typically falls under the range of 77401 to 77499, depending on the specific treatment technique and the number of treatment areas. For four separate areas, you might consider using 77412 (for multiple treatment areas) but should verify with specific clinical details and payer requirements to ensure accurate coding. Always consult the latest CPT codebook or guidelines for the most accurate and up-to-date information.
