A18.17 Tuberculous female pelvic inflammatory disease

Name of the Condition

• Tuberculous female pelvic inflammatory disease
• ICD Code: A18.17

Summary

Tuberculous female pelvic inflammatory disease is a form of extrapulmonary tuberculosis where Mycobacterium tuberculosis infects the female pelvic organs, including the uterus, fallopian tubes, ovaries, or surrounding tissues. This condition typically arises from the spread of TB bacteria from a primary site, such as the lungs, and may present with localized pelvic symptoms or systemic signs of TB.

Causes

Tuberculous female pelvic inflammatory disease is caused by infection with Mycobacterium tuberculosis. The bacteria usually spread to the pelvic organs through the bloodstream or lymphatic system from an existing TB infection elsewhere in the body, such as the lungs or lymph nodes.

Risk Factors

• Close contact with individuals who have active tuberculosis.
• Immunocompromised states, including HIV/AIDS.
• History of tuberculosis infection.
• Poor socioeconomic conditions, which increase exposure risk.
• Living in or traveling to regions with high TB prevalence.

Symptoms

• Pelvic pain or discomfort.
• Abnormal vaginal discharge.
• Menstrual irregularities or pain.
• Systemic symptoms of TB, such as fever, night sweats, or weight loss.
• Infertility or recurrent miscarriages (in chronic cases).

Diagnosis

Diagnosis involves a combination of clinical evaluation, imaging studies (e.g., ultrasound or MRI), and laboratory testing. Samples from pelvic tissues or fluids may be tested for Mycobacterium tuberculosis using culture, nucleic acid amplification tests, or histopathology. A thorough medical history, including TB exposure or prior infection, is also considered.

Treatment Options

Treatment typically involves a standard course of anti-tuberculosis medications, such as isoniazid, rifampin, ethambutol, and pyrazinamide, often for 6–9 months. Surgical intervention may be necessary for complications like abscesses or severe tissue damage. Adjunctive therapies, such as pain management or fertility support, may be used based on individual needs.

Prognosis and Follow-Up

With appropriate treatment, the prognosis is generally favorable, though recovery may take several months. Follow-up care includes monitoring for treatment response, managing side effects of medications, and assessing for long-term complications like infertility or chronic pelvic pain. Regular clinical evaluations and imaging may be recommended during and after treatment.

Complications

• Infertility or ectopic pregnancy due to tubal damage.
• Chronic pelvic pain.
• Formation of tubo-ovarian abscesses.
• Spread of infection to other pelvic or abdominal organs.
• Recurrence of TB if treatment is incomplete.

Lifestyle & Prevention

• Avoid close contact with individuals who have active TB.
• Ensure proper ventilation in living or work environments.
• Maintain good overall health to support immune function.
• Seek prompt medical care for TB symptoms or exposure.
• Follow public health guidelines for TB screening and prevention in high-risk areas.

When to Seek Professional Help

Seek medical attention if you experience persistent pelvic pain, abnormal discharge, unexplained fever, or other systemic TB symptoms. Early evaluation is important for timely diagnosis and treatment, especially if you have a history of TB exposure or infection.

Tips for Medical Coders

When coding for tuberculous female pelvic inflammatory disease (A18.17), ensure documentation supports the diagnosis, including clinical findings, imaging results, or laboratory confirmation of Mycobacterium tuberculosis in pelvic tissues. Verify that the condition is specifically identified as affecting female pelvic organs, as opposed to other genitourinary sites, to avoid miscoding.
