131.8
ICD-9-CMThis code signifies a parasitic infection caused by Trichomonas vaginalis affecting anatomical locations other than the genitourinary tract. While primarily associated with sexually transmitted infections of the lower genital tract, trichomoniasis can manifest in extragenital sites.
Use this code when documentation specifies trichomoniasis in an unusual location, such as the umbilical, respiratory, or oral cavity. Supporting documentation should clearly identify Trichomonas vaginalis as the causative agent and specify the non-genitourinary site of infection.
