Erectile dysfunction following interstitial seed therapy

This code describes erectile dysfunction (ED) that develops as a direct consequence of interstitial seed therapy, a form of brachytherapy often used for prostate cancer. It indicates a specific etiology for the ED, distinguishing it from other causes.

Use this code when documentation clearly links the patient's ED to a history of interstitial seed therapy. This is typically seen in male patients who underwent brachytherapy for prostate cancer and subsequently developed difficulty achieving or maintaining an erection. Documentation should specify the prior interstitial seed therapy and the onset of ED post-treatment.

• Always sequence this code after the primary diagnosis for the ED (e.g., N52.1, N52.8, N52.9).
• Ensure documentation explicitly states "following interstitial seed therapy" or similar phrasing to support the causal link.
• Do not confuse with ED due to other forms of radiation therapy or surgical procedures; specific codes exist for those etiologies.
