What 77334 covers

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.

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.

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 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.
