Tuberculous chorioretinitis

This code represents an inflammatory condition of the choroid and retina caused by Mycobacterium tuberculosis. It is a form of ocular tuberculosis, often presenting with granulomatous inflammation and potentially leading to vision impairment.

Assign this code when documentation clearly indicates a diagnosis of chorioretinitis specifically attributed to tuberculosis. Supporting documentation should include clinical findings, imaging (e.g., fundoscopy, OCT), and often a positive diagnostic test for tuberculosis (e.g., PPD, IGRA, culture).

• Always code the underlying infectious agent (B90.8) as a secondary diagnosis.
• Specify laterality if documented (e.g., H30.81- for other chorioretinal inflammations).
• Ensure documentation differentiates tuberculous chorioretinitis from other causes of chorioretinitis.
