What 77333 covers
This code covers the design and construction of a radiation treatment aid used to shape or modify the beam or help position the patient reproducibly. Examples of treatment aids across this code family include shielding blocks, bolus, and immobilization devices. Radiation oncologists, dosimetrists, and radiation therapy teams use these devices in external-beam treatment planning and delivery. The intermediate level is selected by the device’s design and construction complexity, not simply by the diagnosis or treatment site.
Choose this level when the documented device is more involved than a simple aid but does not meet the complex level. Record what was designed or fabricated and how it supports treatment; report distinct devices at the applicable level when separately documented. CMS recognizes professional and technical components: modifier 26 identifies the professional component, modifier TC the technical component involving equipment and staff, and no modifier represents the global service.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

77333 billing questions
How does 77333 differ from 77332 and 77334?
These codes distinguish treatment aids by design and construction complexity. Use 77332 for the simple level, 77333 for the intermediate level, and 77334 for the complex level.
What documentation supports 77333?
Document the particular aid designed or constructed and its role in shaping the radiation beam or supporting reproducible patient positioning. The record should support the intermediate complexity level.
Can 77333 be reported with modifier 26 or TC?
CMS recognizes separately priced professional and technical components. Modifier 26 identifies the professional component, TC identifies the equipment-and-staff component, and billing without either modifier represents the global service.
How should units be determined?
Base reporting on each distinct treatment aid furnished and documented, rather than the number of treatment fractions or beam angles. Select the appropriate complexity level for each aid.
Is dose calculation included in 77333?
77333 represents the treatment aid, while 77300 represents a radiation therapy dose calculation. Report both only when the record supports each as a distinct service.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
