About 77334: Complex radiation treatment device design and construction
Design and construction of a complex radiation treatment device, such as an irregular shielding block, compensator, or custom mold, reported for each distinct device.
This service involves designing and constructing a complex device used to shape radiation or position the patient for treatment. Examples include irregular shielding blocks, special shields, compensators, and custom molds or casts. A radiation oncologist provides the professional work, while dosimetrists, physicists, or mold room staff may help design and fabricate the device. The work takes place in hospital radiation oncology departments and freestanding treatment centers.
Report one unit for each distinct complex device constructed, rather than one unit for every field in which the same device is used. Choose among 77332, 77333, and 77334 by the documented device design and construction, not the complexity of the treatment plan. Records should identify each device, its purpose, and the work supporting its complexity. CMS prices a professional component, reported with modifier 26, and a technical component, reported with modifier TC. An unmodified claim represents both components when the billing entity furnishes both; a physician billing separately for the professional work reports 26.
CMS billing rules for 77334
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

77332 covers simple treatment devices. Choose 77334 when the documented device requires complex design and construction, rather than assigning a level based on treatment-plan complexity.
$444.40
77338 covers multileaf collimator device design and construction for an IMRT plan. Use 77334 for a distinct complex physical treatment device, such as a custom mold or irregular block.

How this local rate is calculated
Each RVU component is multiplied by its own geographic practice cost index (GPCI). The three adjusted components are added, then multiplied by the conversion factor. These are the inputs used for 77334 in Idaho.

77334 billing questions
How many units of 77334 can be reported?
Report one unit for each distinct complex device designed and constructed. Document each device separately; using the same device for multiple fields does not make it multiple devices.
When is 77334 chosen over 77332 or 77333?
Select the level by the device's documented design and construction. Complex devices include irregular blocks, compensators, and custom molds or casts; 77332 covers simple devices, while 77333 covers intermediate devices such as multiple standard blocks or bite blocks.
Can 77334 be billed for an IMRT multileaf collimator design?
Report the IMRT multileaf collimator device design under 77338, not 77334. A distinct complex physical device may also support 77334 when separately constructed and documented.
How are the professional and technical components billed?
A physician billing separately for the professional work uses modifier 26. Modifier TC identifies the technical component on a claim for that component, while an unmodified claim represents both components when the billing entity furnishes both.
Is a device made at simulation separately reportable?
A distinct complex device designed and constructed at simulation may be reported with the simulation service when both are performed and documented. Do not assign a mask or other setup item to 77334 solely because it was made at simulation.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
