Radiation oncology

About 77285: Intermediate radiotherapy field simulation

Reports intermediate-complexity simulation for radiation treatment, where imaging and setup establish the patient's position and treatment-field arrangement.

Radiotherapy simulation establishes a reproducible treatment position and helps determine the arrangement of radiation fields before treatment begins. A radiation oncologist directs the clinical work, with radiation therapists typically operating the simulation equipment and assisting with patient setup. The service is performed in a radiation oncology department or other setting equipped for treatment simulation; it is not the delivery of therapeutic radiation.

Select 77285 when the documented simulation meets intermediate rather than simple or complex criteria. The record should support the simulation work performed, including patient positioning and the imaging or field-definition work that establishes the treatment setup. CMS recognizes separate professional and technical components: modifier 26 identifies the professional interpretation, modifier TC identifies the equipment and staff, and reporting without either modifier represents the global service.

CMS billing rules for 77285

Professional and technical components
Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

77285 billing questions

How do I distinguish 77285 from 77280 or 77290?

Choose among these simulation levels according to the documented complexity of the work and the applicable CPT criteria. Do not assign the intermediate level based only on the number of treatment fields.

What does modifier 26 represent for 77285?

Modifier 26 reports the professional component, meaning the physician's interpretation. The unmodified code represents the global service when one entity reports both components.

When is modifier TC appropriate?

Use TC for the technical component, which covers the simulation equipment and staff. A claim without 26 or TC represents the global service.

Can 77285 be reported with treatment planning?

Simulation establishes positioning and field arrangement, while treatment planning represents separate planning work. Report each service when it was performed and the documentation supports it.

What documentation supports the intermediate level?

Document the simulation and patient setup, the imaging or field-definition work performed, and the details that establish intermediate rather than simple or complex work.

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.
