What 77470 covers
A radiation oncologist reports this service when a treatment circumstance requires substantial work beyond the usual radiation planning and treatment process. Examples include total body irradiation, hemibody irradiation, hyperthermia combined with radiation, or coordinating radiation with concurrent chemotherapy. The added work may involve specialized preparation, coordination, or treatment considerations; the specific circumstance and work performed should be evident in the record.
Report 77470 for the additional special-treatment work, not as a substitute for applicable radiation delivery or management services. Documentation should explain why the case required extra effort and describe the work attributable to that circumstance. CMS identifies professional and technical components: modifier 26 represents the professional interpretation, modifier TC represents equipment and staff, and an unmodified claim represents the global service. CMS lists both modifiers as separately priced.
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.

77470 represents additional work tied to a special treatment circumstance. Codes such as 77402, 77407, and 77412 describe radiation treatment delivery at different levels.
Can 77470 be reported with radiation delivery?
It may be reported with the applicable delivery service when the record supports additional special-treatment work. It does not replace the code for treatment delivery.
What documentation supports 77470?
Document the unusual treatment circumstance, why it required work beyond the usual process, and the additional work performed. Naming a complex diagnosis alone does not explain the service.
When should modifier 26 or TC be used?
CMS identifies modifier 26 for the professional interpretation and modifier TC for equipment and staff. Without either modifier, the claim represents the global service.
Is 77470 the code for routine radiation treatment management?
No. Routine management is represented by applicable management services, such as 77427 for radiation treatment management reported in five-treatment increments. 77470 addresses added work for a special treatment circumstance.
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.
