Epididymitis

This code represents non-infectious inflammation of the epididymis, the coiled tube located at the back of the testicle that stores and carries sperm. It is characterized by pain, swelling, and tenderness in the scrotum, often without evidence of bacterial infection.

Use this code when documentation clearly indicates epididymitis without an identified infectious etiology. This typically applies to cases where urinalysis and cultures are negative, or when the inflammation is attributed to trauma, chemical irritants, or autoimmune processes.

• Differentiate from N45.0 (Orchitis, epididymitis and epididymo-orchitis with abscess) and N45.9 (Epididymitis, unspecified) based on documentation of abscess or lack of specificity.
• Always review for laterality (e.g., right, left, bilateral) if specified in the clinical notes, though this code does not allow for laterality assignment.
• Ensure the physician's documentation explicitly rules out an infectious cause to support the "non-infectious" designation.
