About 77437: Superficial radiation treatment delivery
Reports delivery of a superficial radiation treatment fraction using equipment operating at 150 kV or less, commonly for selected skin lesions.
This code represents delivery of a superficial radiation treatment fraction with an x-ray unit operating at 150 kV or less. Radiation therapists typically deliver the treatment in a radiation oncology setting under the direction of a radiation oncologist. Superficial treatment may be selected for appropriately situated skin lesions, including some nonmelanoma skin cancers, when the prescribed treatment approach and lesion depth suit this energy range.
Report the code for the delivered fraction, not for treatment planning or ongoing management. Documentation should identify the treated site, the fraction delivered, and the equipment energy range supporting selection of this code rather than the orthovoltage code. CMS classifies 77437 as a technical-component-only service: it represents the treatment delivery, while interpretation is covered by a separate code. Do not use this code to represent a separately billed professional interpretation.

77437 billing questions
How does 77437 differ from 77438?
77437 is for superficial treatment using equipment at 150 kV or less. Use 77438 for orthovoltage treatment above 150 kV through 500 kV.
Is 77437 reported for each treatment fraction?
Yes. Report it for the superficial treatment fraction delivered; planning and treatment management are distinct services.
Does 77437 include the physician's interpretation?
No. CMS identifies 77437 as technical-component-only, with interpretation covered by a separate code.
What documentation supports reporting 77437?
Document the treated site, the fraction delivered, and the unit's energy range. The record should support use of superficial treatment at 150 kV or less rather than orthovoltage treatment.
Can 77437 be used for conventional external-beam delivery?
No. It describes superficial radiation treatment at the specified energy range, not conventional external-beam delivery reported by treatment-delivery level.
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.
