What 77412 covers
Code 77412 represents delivery of a complex external-beam radiation treatment fraction, commonly using a medical linear accelerator in an outpatient cancer center or hospital radiation department. Radiation therapists carry out the planned treatment under the radiation oncologist’s direction. The treatment record should establish the delivered fraction and the setup or delivery features supporting the complex level; the diagnosis or equipment alone does not establish that level.
Report the code for each qualifying treatment delivery, using the documented complexity to distinguish it from the simple and intermediate delivery levels. Retain the treatment plan and fraction record, including the relevant fields, ports, or delivery setup details. CMS classifies 77412 as a technical-component-only service: a separate code covers interpretation, so this code represents the technical delivery rather than the physician’s interpretation.

77412 billing questions
How is 77412 distinguished from 77407?
Select the level supported by the documented treatment-delivery complexity. The treatment record should support why the session meets the complex level rather than the intermediate level.
Is 77412 reported for each treatment fraction?
Report it for each qualifying complex treatment delivery. The record should identify the date and fraction delivered.
Does 77412 include the physician’s interpretation?
No. CMS identifies 77412 as technical-component-only; a separate code covers interpretation.
Can 77412 be used for IMRT delivery?
When the service is IMRT delivery, consider the IMRT-specific delivery code, such as 77386, rather than selecting 77412 solely because the treatment is complex.
What documentation supports the complex level?
Keep the treatment plan and delivery record showing the fraction and the setup or delivery details that support complex treatment delivery.
