Atrophy of testis

This code signifies a reduction in the size and function of one or both testes. It indicates a degenerative process where testicular tissue wastes away, potentially leading to impaired spermatogenesis and hormone production.

Apply this code when documentation clearly indicates a diagnosis of testicular atrophy, regardless of the underlying cause (e.g., post-orchitis, cryptorchidism, vascular compromise, aging). Supporting documentation should include physician notes detailing the physical examination findings (e.g., small, soft testes) or imaging reports confirming reduced testicular volume.

• Differentiate from hypogonadism (257.2) if atrophy is not explicitly documented as the cause.
• Always code any underlying cause of the atrophy, if known, as a primary diagnosis when appropriate.
• Ensure laterality is specified in the medical record (unilateral or bilateral) for more precise reporting, though this code does not differentiate.
