About 77370: Special radiation physics consultation
A medical physicist performs a physician-requested, case-specific analysis or measurement for unusual radiation treatment circumstances beyond routine planning and review.
A radiation oncologist may request a medical physicist’s focused analysis when a patient’s treatment presents unusual technical circumstances. The physicist may perform case-specific calculations or measurements and assess how those findings affect the treatment setup or delivery. This work is distinct from routine dose planning and ongoing physics review during a course of radiation therapy.
Report 77370 for the special technical consultation, supported by the physician’s request and a written physicist report describing the unusual circumstance, work performed, and findings. The record should show why routine planning or review was insufficient. CMS classifies this as a technical-component-only code; a separate code covers interpretation. The fee schedule assigns no physician work RVUs to this code, reflecting that its reported service is the technical physics work rather than interpretation.

77370 billing questions
How does 77370 differ from 77336?
Use 77370 for a physician-requested, case-specific physics analysis prompted by unusual treatment circumstances. Code 77336 represents ongoing physics review during a radiation treatment course.
Can routine dose calculation be reported as 77370?
No. A routine dose calculation is distinct from the special consultation reported with 77370; document the unusual circumstance and the additional physics work.
Does 77370 include the physician’s interpretation?
CMS identifies 77370 as technical-component-only. Interpretation is covered by a separate code.
What documentation supports 77370?
Keep the radiation oncologist’s request and the physicist’s report. The report should identify the unusual treatment issue, the calculations or measurements performed, and the resulting findings.
Is 77370 reported for every complex radiation plan?
No. Complexity alone is not the service; the record should support a distinct, physician-requested physics consultation beyond routine planning or review.
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.
