Erectile dysfunction following radiation therapy

This code identifies erectile dysfunction (ED) that develops as a direct consequence of radiation therapy. It describes a male patient experiencing an inability to achieve or maintain an erection sufficient for satisfactory sexual performance, where the etiology is directly attributable to prior radiation treatment, often for pelvic malignancies.

Use this code when documentation clearly links the patient's ED to a history of radiation therapy. This typically applies to patients who underwent radiation for prostate cancer, bladder cancer, or other pelvic cancers. Supporting documentation should include a history of radiation treatment and a diagnosis of ED.

• Always sequence this code after the underlying condition (e.g., history of prostate cancer) if still active, or as a primary diagnosis if ED is the sole reason for the encounter.
• Distinguish from ED due to other causes (e.g., vascular, neurological, psychogenic) which have different ICD-10-CM codes.
• Ensure the medical record explicitly states "post-radiation" or "due to radiation therapy" in relation to the erectile dysfunction.
