Encounter for antineoplastic radiation therapy

This code signifies a patient's visit specifically for the administration of radiation therapy intended to treat cancer. It indicates that the primary purpose of the encounter is the delivery of therapeutic radiation, rather than diagnosis, screening, or follow-up care without active treatment.

Apply this code when a patient presents for a scheduled session of external beam radiation, brachytherapy, or other forms of radiation treatment for a malignant neoplasm. It is appropriate for each encounter where radiation therapy is provided as part of a cancer treatment plan.

• Always sequence this code as the primary diagnosis when the reason for the encounter is solely for radiation therapy.
• Do not use this code for follow-up visits after radiation therapy has concluded, or for encounters where radiation is being considered but not yet administered.
• Remember to also code the specific type of malignancy being treated, as well as any relevant complications or adverse effects of the therapy.
