ICD-10 Code A18.18 – Tuberculosis of other female genital organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A18.18 – Tuberculosis of other female genital organs
What it is
This code identifies tuberculosis infection involving female genital organs other than the uterus, cervix, ovaries, or fallopian tubes. Use it when documentation specifies a tuberculous process in another female reproductive structure.
Clinical signs
Findings may include chronic pelvic symptoms, abnormal genital tract masses, or infertility, but clinical features vary; refer to documentation. Diagnosis is usually supported by pathology, culture, imaging, or clinician-confirmed tuberculous involvement.
When to use this code
Use A18.18 when the record clearly states tuberculosis affecting another female genital organ and the site is not better represented by a more specific genital TB code. Apply it for confirmed or documented presumed genital tuberculosis affecting an unspecified other female organ.
If the provider names the exact structure and it falls under a more specific code, choose that code instead. Check documentation when the anatomic site is unclear or when tuberculosis is only suspected.
Do not use for
Do not use this code for tuberculosis of the uterus, cervix, ovaries, or fallopian tubes. Also avoid it when the condition is non-tuberculous pelvic infection or the documentation does not confirm a female genital TB site.
Coding tip
Confirm the exact female genital organ involved before assigning A18.18, and query the provider if the anatomic site is vague.
