ICD-10 Code A18.53 – Tuberculous chorioretinitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A18.53 – Tuberculous chorioretinitis
What it is
Tuberculous chorioretinitis is inflammation of the choroid and retina caused by Mycobacterium tuberculosis. Use this code when the eye involvement is documented as tuberculous in origin.
Clinical signs
Findings may include decreased vision, ocular inflammation, and retinal or choroidal lesions. Clinical features vary; refer to documentation, especially if the diagnosis is based on ophthalmic examination or supportive evidence of tuberculosis.
When to use this code
Use A18.53 when the provider documents tuberculous chorioretinitis, ocular tuberculosis, or chorioretinal involvement due to TB. It is appropriate when the eye condition is clearly linked to tuberculosis and not coded as a nonspecific uveitis or other retinal disorder.
Do not use for
Do not use this code for chorioretinitis without a tuberculosis cause. Check documentation if the record only states suspected TB, latent TB, or another ocular inflammatory condition.
Coding tip
Confirm that tuberculosis is explicitly documented as the cause before assigning A18.53.
