Therapeutic radiology simulation-aided field setting; simple
Modifiers 26 (professional component) and TC (technical component) can be used if appropriate.
Medical necessity must be established for radiation therapy, justifying the simulation procedure. Documentation should link the simulation to the treatment plan and the patient's diagnosis.
In simple words: The doctor uses imaging technology to plan the placement and size of the radiation beams for your treatment. This is a straightforward planning procedure.
This code represents a simple level of therapeutic radiology simulation-aided field setting.It involves the use of a simulator or other imaging modality to determine the size and location of ports for radiation therapy.This typically involves a single treatment area encompassed in a single port or simple parallel opposed ports, with simple or no blocking.
Example 1: A patient with a localized skin lesion requires radiation therapy. A simple simulation is performed to target the lesion with a single radiation port., A patient with early-stage breast cancer undergoes simulation for radiation to the breast using parallel opposed ports., A patient receives palliative radiation for a single bone metastasis. A simple simulation helps direct the radiation to the affected bone.
Medical record should include details of the simulation process, including the area treated, type of imaging used, and port placement.
- Modifier TC rule: Modifier TC can be appended when reporting the technical component only, though payer policies may vary (e.g., hospitals may be exempt).
