Article Overview
This short radiology oncology article addresses coding and documentation questions for treatment planning in stereotactic radiosurgery and stereotactic body radiotherapy. It is aimed at coding professionals and clinicians who work with radiation oncology services and need to understand when planning updates or separate treatment sites may affect plan structure and documentation. The article is presented as a focused Q&A from a CPT Assistant radiology oncology issue.
Why This Topic Matters
Accurate treatment-planning documentation is important in radiation oncology because planning services can vary when anatomy, tumor burden, or the number of disease sites changes during care. This article helps readers understand the general circumstances that may prompt additional planning and why clear documentation is emphasized.
