ICD-10 Code H30.893 – Other chorioretinal inflammations, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.893 – Other chorioretinal inflammations, bilateral
What it is
This code identifies inflammation involving both the choroid and retina when the condition does not fit a more specific chorioretinal diagnosis. Use it for bilateral disease documented as “other” chorioretinal inflammation.
Clinical signs
Findings may include decreased vision, floaters, photophobia, or ocular inflammation on examination. Clinical features vary; refer to documentation and the ophthalmology assessment.
When to use this code
Use H30.893 when the provider documents bilateral chorioretinal inflammation and does not name a more specific subtype. It is appropriate when the record clearly supports involvement of both eyes. If the note only says “chorioretinitis” or does not specify laterality, check documentation.
Do not use for
Do not use this code for unilateral chorioretinal inflammation or for a more specific chorioretinal disorder with its own ICD-10 code. Do not assume bilateral involvement without explicit documentation.
Coding tip
Confirm both the bilateral laterality and the nonspecific “other” diagnosis wording before assigning H30.893.
