Radiation therapy codes underwent significant changes for 2015. Teletherapy isodose planning and brachytherapy codes now include the basic dosimetry calculation and IMRT codes now include guidance and tracking. Also radiation treatment delivery codes were deleted in 2015.
77306 Teletherapy isodose plan; simple (1 or 2 unmodified ports directed to a single area of interest), includes basic dosimetry calculation(s)
77307 Teletherapy isodose plan; complex (multiple treatment areas, tangential ports, the use of wedges, blocking, rotational beam, or special beam considerations), includes basic dosimetry calculation(s)
77316 Brachytherapy isodose plan; simple (calculation[s] made from 1 to 4 sources, or remote afterloading brachytherapy, 1 channel), includes basic dosimetry calculation(s)
77317 Brachytherapy isodose plan; intermediate (calculation[s] made from 5 to 10 sources, or remote afterloading brachytherapy, 2-12 channels), includes basic dosimetry calculation(s)
77318 Brachytherapy isodose plan; complex (calculation[s] made from over 10 sources, or remote afterloading brachytherapy, over 12 channels), includes basic dosimetry calculation(s)
77385 Intensity modulated radiation treatment delivery (IMRT), includes guidance and tracking, when performed; simple
77386 Intensity modulated radiation treatment delivery (IMRT), includes guidance and tracking, when performed; complex
77387 Guidance for localization of target volume for delivery of radiation treatment delivery, includes intrafraction tracking, when performed
