ICD-10 Code A18.7 – Tuberculosis of adrenal glands (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A18.7 – Tuberculosis of adrenal glands
What it is
A18.7 identifies tuberculosis infection involving the adrenal glands. Use it when documentation states adrenal tuberculosis, usually as part of extrapulmonary TB.
Clinical signs
Clinical features vary; refer to documentation. Adrenal involvement may be noted with constitutional tuberculosis findings and evidence of adrenal disease on imaging or pathology.
When to use this code
Use A18.7 when the record clearly documents tuberculosis of one or both adrenal glands. It may appear as a confirmed extrapulmonary TB diagnosis, or as adrenal TB supported by biopsy, imaging, or specialist assessment. If the site is not specified, check documentation before coding.
Do not use for
Do not use this code for nonspecific adrenal disorders, adrenal insufficiency without documented tuberculosis, or suspected TB without confirmation. Check documentation if the adrenal involvement is not clearly stated.
Coding tip
Verify that tuberculosis is linked to the adrenal glands, not just a history of TB or an adrenal mass.
