Radiation oncology
About 77431: Radiation management for one or two treatments
Reports physician management of an external-beam radiation course limited to one or two treatments, rather than the usual five-treatment management interval.
Code 77431 represents the radiation oncologist’s management of a course with only one or two treatments. The physician’s work includes evaluating the patient during treatment and reviewing the treatment plan and relevant treatment information, such as dosimetry and imaging, to manage the course. It is distinct from coding the radiation delivery itself, which describes the technical treatment service. Radiation oncologists typically provide this management in a hospital or freestanding radiation therapy department.
Select 77431 when the course has one or two treatments; do not use it for a routine five-treatment management interval. The record should support the number of treatments and the physician’s management work. CMS identifies 77431 as a professional-component-only code for interpretation and report, with a separate code covering the technical portion. Report the professional service as represented by this code; do not treat it as a split professional-and-technical code.

77431 billing questions
When should 77431 be selected instead of 77427?
Use 77431 for management of a course with only one or two treatments. Code 77427 represents the usual five-treatment management interval.
Can radiation delivery be reported separately?
Yes. The management service is distinct from the technical radiation delivery service, which is represented by a separate code when supported.
Should modifier 26 or TC be appended?
No. CMS identifies 77431 as professional-component-only, covering interpretation and report; it is not a code split into professional and technical portions.
What documentation supports reporting 77431?
Document the course’s one- or two-treatment count and the radiation oncologist’s management work, including review of relevant treatment information.
Is 77431 the management code for stereotactic treatment?
Not when a more specific stereotactic management code describes the service. Codes 77432 and 77435 address stereotactic treatment circumstances.
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.
