What 77427 covers

This code covers a radiation oncologist's ongoing oversight of fractionated external beam therapy, such as a multiweek course for breast, prostate, lung, or head and neck cancer. Management includes reviewing verification images and dosimetry, checking dose delivery and treatment parameters, assessing patient setup, and evaluating treatment response and side effects. The service is provided in hospital outpatient departments and freestanding radiation oncology centers.

Report one unit for each five delivered treatment fractions, regardless of calendar days. Distinct twice-daily treatment sessions count separately. At the end of a course, three or four fractions beyond the last full group of five support another unit; one or two do not. Use 77431 instead when the entire course consists of only one or two fractions. Documentation should support the oncologist's patient evaluation and review of treatment images, dosimetry, and delivery. Medicare treats 77427 as professional-only work: do not append modifier 26. Technical delivery and imaging are reported with separate codes when performed.

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.

77427 billing questions

How many units are reported for a 28-fraction course?

Report six units: five for the first 25 fractions and one for the remaining three. A remainder of only one or two fractions would not support another unit.

When should 77431 be used instead?

Use 77431 when the entire treatment course consists of only one or two fractions. A course of three or more fractions is managed with 77427.

Can E/M visits be billed during the treatment course?

Routine on-treatment evaluation for the condition being irradiated is included in treatment management. A separately identifiable visit for an unrelated problem may be reported when documented; append modifier 25 to the E/M code when needed to distinguish a same-day service.

Does modifier 26 need to be appended?

No. 77427 is already a professional-only code; technical delivery and imaging are reported under separate codes.

Do twice-daily treatments count as two fractions?

Yes. When treatment is delivered in two distinct sessions on the same day, each session counts toward the five-treatment unit.

Is review of port films or verification images separately billable?

The oncologist's review is part of treatment management. Port image acquisition, such as 77417, is a separate technical service.

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.
