Encounter for radiotherapy

This code signifies a patient's visit specifically for the administration of radiation therapy. It indicates that the primary purpose of the encounter is to receive treatment using high-energy radiation to destroy cancer cells or reduce tumor size. This is a service code, not a diagnosis of the underlying condition.

Use this code for all encounters where a patient presents for a scheduled radiotherapy session. This includes initial treatments, subsequent fractions of a treatment course, and follow-up visits solely for the purpose of receiving radiation. It is appropriate for both external beam radiation and brachytherapy.

• Always sequence this code as a secondary diagnosis, following the primary malignancy or condition requiring radiotherapy.
• Do not use this code for diagnostic imaging procedures that utilize radiation, such as X-rays or CT scans.
• Ensure the specific type of radiotherapy procedure (e.g., CPT codes for radiation treatment delivery) is also coded to fully describe the service.
