Because Erectile Dysfunction can be caused by several different physiological conditions other than circulatory problems (Parkinson's, psychosexual issues, cholesterol etc) it would be incorrect to use E11.59. The correct codes would be E11.69, N52.1 (ED due to diseases classified elsewhere).I have an encounter where the provider documents, Erectile Dysfunction due to DM. It is clearly linked. As in the first post, would it be E11.69 or E11.59?
