ICD-10 Code A18.17 – Tuberculous Female Pelvic Inflammatory Disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A18.17 – Tuberculous female pelvic inflammatory disease
What it is
A18.17 identifies pelvic inflammatory disease in a female caused by Mycobacterium tuberculosis. Use it when the pelvic infection is documented as tuberculous rather than routine bacterial PID.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include chronic pelvic pain, infertility, menstrual irregularity, adnexal tenderness, or evidence of genital tract tuberculosis.
When to use this code
Use A18.17 when the record clearly states tuberculous pelvic inflammatory disease, tuberculous salpingitis, or tuberculous infection involving the female pelvic organs. It may appear in a patient with known tuberculosis and pelvic disease confirmed by imaging, pathology, or specialist assessment.
Code it only when the provider links the pelvic inflammatory condition to tuberculosis. If the chart only says PID, pelvic pain, or infertility without a tuberculous cause, check documentation before assigning this code.
Do not use for
Do not use this code for nonspecific pelvic inflammatory disease, sexually transmitted PID, or abdominal tuberculosis without female pelvic involvement. Check documentation if the site or cause is unclear.
Coding tip
Look for explicit wording such as “tuberculous” or “TB” tied to the female pelvis before coding A18.17.
