ICD 10 & 11 Sexually Transmissible Infections – Chlamydia

Definition of Sexually Transmissible Infections Due To Chlamydia: An infection with the gram-negative bacteria Chlamydia trachomatis. This infection may be asymptomatic or characterised by fever, painful urination, urinary urgency, dyspareunia, female genitalia bleeding or discharge, pain in the abdomen in females and by fever, urethritis, painful urination, discharge from the male genitalia, swollen or tender testicles in males. Transmission is by rectal passage, female genitalia, or oral sex. Confirmation is by identification of Chlamydia trachomatis.

Chlamydial Lymphogranuloma

Definition of Chlamydial lymphogranuloma: A disease of the inguinal lymph glands, caused by an infection with the gram-negative bacteria Chlamydia trachomatis. This disease is characterised by a genital ulcer, buboes, abscesses in the groin, blood in faeces, tenesmus, or proctocolitis. Transmission is by sexual contact. Confirmation is by identification of Chlamydia trachomatis in a blood sample or by polymerase chain reaction tests.

Chancroid

Definition of Chancroid: A disease caused by an infection with the gram-negative bacteria Haemophilus ducreyi. This disease is characterised by painful ulcer(s) on the genitalia. Transmission is by sexual contact. Confirmation is by identification of Haemophilus ducreyi from the ulcer exudate.

Inclusions:

Granuloma Inguinale

Definition of Granuloma inguinale: A disease caused by infection with the gram-negative bacterium Klebsiella granulomatis. It commonly presents with painless genital ulceration following contact with an infected sexual partner. Small, painless nodules appear after an incubation period of about 10–40 days; later the nodules break down to create open, fleshy, oozing ulcers which gradually extend, mutilating the infected tissue. The lesions occur at the region of contact and are typically found on the shaft of the male genitalia, the female genitals, or the perineum.

Anogenital warts

Definition of Anogenital warts: Anogenital warts are due to an infection of anogenital skin and mucous membranes by certain human papilloma viruses, most commonly HPV subtypes 6,11,16 and 18. Transmission is predominantly by sexual contact. They manifest typically as flat plaques or papillomatous, keratinous growths on and adjacent to the external genitalia and anus. Some HPV subtypes, including types 16 and 18, are oncogenic and predispose to the development of anogenital cancers.

Inclusions:

• Condylomata acuminata

Coded Elsewhere:

• Anogenital verrucous carcinoma of Buschke and Lowenstein

1A95.0 Warts around rectal passage

Definition of rectal passage warts: Infection of the rectal passage or surrounding skin by human papillomavirus (HPV). Although the majority of such infections are sexually transmitted and caused by HPV subtypes responsible for genital warts, autoinoculation from common warts, especially on the hands in children, may also cause warts.

Inclusions:

• Rectal passage condyloma acuminata

1A95.1 Genital warts

Definition of Genital warts: Infection of anogenital mucosa or skin by the human papillomavirus. The infection is commonly asymptomatic but manifests typically as flat, papular or pedunculated growths depending on the site of infection. Transmission is by normally by sexual contact.

1A95.2 Extragenital condylomata acuminata

Definition of Extragenital condylomata acuminata: Anogenital warts transmitted to extragenital sites (i.e. beyond the anogenital region). This may be through autoinoculation of anogenital wart virus to moist, intertriginous sites on the abdomen or under the breasts, or as a result of sexual activity, particularly to the lips and oral cavity.

Inclusions:

• Anogenital warts affecting sites other than the anogenital area
