601.4
ICD-9-CMThis code signifies inflammation of the prostate gland that occurs as a manifestation or complication of another underlying disease process. It indicates that the prostatitis is not a primary, standalone condition but rather secondary to another classified illness.
Use this code when documentation clearly links prostatitis to an underlying systemic disease, such as an autoimmune disorder, a specific infectious disease, or a metabolic condition. The medical record must explicitly state the primary disease causing the prostatitis.
