What 77332 covers
77332 covers the design and construction of a straightforward device used to shape or support radiation treatment, such as a simple beam block, bolus, or basic immobilization aid. Radiation oncologists prescribe the treatment approach; medical physicists, dosimetrists, and radiation therapists may contribute to planning, fabrication, and verification in radiation oncology clinics or hospital departments. The device is specific to the patient's treatment setup, rather than a dose calculation or the treatment delivery itself.
Choose this level when the device work is simple; use 77333 or 77334 when documented device complexity reaches those higher levels. The record should identify the device, treatment site and purpose, and work supporting its simple design and construction. CMS identifies separately priced professional and technical components: modifier 26 reports the professional interpretation, modifier TC reports equipment and staff, and billing without either 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.

77332 billing questions
How does 77332 differ from 77333 and 77334?
77332 is for simple device work. Select 77333 or 77334 when the documented device design and construction meet the intermediate or complex level, respectively.
Can a simple block or bolus support 77332?
Yes. A simple beam block or simple bolus is a typical example; the record should show the device and its role in the patient's treatment setup.
Does 77332 report radiation dose calculation?
No. It represents the treatment aid's design and construction, while 77300 represents a radiation dose calculation when that separate service is performed.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation and TC for the technical portion involving equipment and staff. Billing without either modifier represents the global service.
What documentation supports the simple level?
Identify the aid, the treatment site and purpose, and the design and construction work showing why the device is simple rather than intermediate or complex.
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.
