Trichomoniasis of other sites

This code signifies an infection caused by the parasite Trichomonas vaginalis occurring in anatomical locations other than the genitourinary tract. While trichomoniasis most commonly affects the vagina or urethra, it can rarely manifest in extragenital sites.

Apply this code when documentation specifies trichomoniasis affecting sites such as the rectum, pharynx, or other non-genitourinary locations. This diagnosis requires definitive laboratory confirmation or strong clinical evidence of Trichomonas vaginalis infection in an atypical site.

• Ensure documentation clearly specifies a non-genitourinary site of infection; otherwise, a more specific genitourinary trichomoniasis code may be appropriate.
• Do not use this code for unspecified trichomoniasis; seek clarification from the provider if the site is not documented.
• Consider co-reporting with codes for symptoms or manifestations related to the specific extragenital site of infection.
