About 77336: Weekly medical physics review

Reports a medical physicist’s recurring review of radiation treatment records and delivery parameters during a course of therapy, counted by week.

A medical physicist performs this recurring technical review during external-beam radiation therapy. The work can include checking treatment documentation, patient-specific parameters, dosimetry, and quality assurance for treatment delivery. It is distinct from creating the initial treatment plan and from the radiation oncologist’s treatment-management service.

Report the service by week of therapy, rather than by treatment fraction or each chart item reviewed. Documentation should support the week’s review and identify the treatment records or parameters assessed. CMS classifies 77336 as technical-component-only, with no physician-work RVU; a separate code covers interpretation. The technical review and any separately reported physician service must represent distinct documented work.

77336 billing questions

Is 77336 reported per treatment fraction?

No. It is reported per week of therapy, based on the documented weekly physics review rather than the number of fractions delivered.

How does 77336 differ from 77370?

77336 represents recurring physics review during treatment. 77370 is for a separately requested, special medical physics consultation addressing a specific problem.

Can 77336 be billed with radiation treatment management?

Yes, the weekly physics review is a distinct technical service from the radiation oncologist’s treatment-management service, reported separately when each service is performed and documented.

Should modifier 26 be appended to 77336?

No. CMS identifies 77336 as technical-component-only; a separate code covers interpretation.

What documentation supports 77336?

Record the week of therapy reviewed and the treatment documentation, parameters, dosimetry, or delivery quality checks assessed by the medical physicist.
