ICD-10 Code A18.16 – Tuberculosis of cervix (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A18.16 – Tuberculosis of cervix
What it is
A18.16 identifies tuberculosis infection involving the cervix. Use it when documentation specifically states cervical tuberculosis, usually as part of extrapulmonary TB.
Clinical signs
Clinical features vary; refer to documentation. Reported findings may include abnormal vaginal bleeding, discharge, pelvic pain, or a cervical lesion, but confirmation should come from the clinician’s record.
When to use this code
Use this code when the provider documents tuberculosis of the cervix, whether suspected clinically or confirmed by pathology, culture, or other accepted evaluation. It may appear with other extrapulmonary TB codes if multiple sites are involved. If the record only says genital TB or pelvic TB, check documentation before assigning A18.16.
Do not use for
Do not use this code for pulmonary tuberculosis, general TB exposure, or nonspecific female genital infections. If the cervix is not explicitly involved, check documentation.
Coding tip
Code A18.16 only when cervical involvement is clearly documented; if the site is unclear, query the provider.
