Q55.21
ICD-10-CMThis code describes the congenital anomaly characterized by the presence of more than two testes. It is a rare condition where supernumerary testes, which may or may not be functional, are found in addition to the normal pair.
Assign this code when documentation clearly indicates the diagnosis of polyorchism, meaning the patient has three or more testes. This diagnosis is typically made through imaging studies (e.g., ultrasound, MRI) or surgical exploration confirming the presence of extra testicular tissue.
