ICD-10 Code H30.93 – Unspecified chorioretinal inflammation, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.93 – Unspecified chorioretinal inflammation, bilateral
What it is
This code identifies inflammation involving both the choroid and retina, without a more specific cause or subtype documented. Use it when the record confirms bilateral chorioretinal inflammation but does not further define the condition.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include blurred vision, floaters, or ocular inflammation noted on eye examination, but the chart must support bilateral chorioretinal involvement.
When to use this code
Use H30.93 when the provider documents unspecified chorioretinal inflammation in both eyes and no more precise diagnosis is available. It is appropriate when laterality is clear, but the cause, type, or extent is not specified. Check documentation if the note only says “chorioretinitis” or gives a unilateral diagnosis.
Do not use for
Do not use this code for unilateral disease, a more specific chorioretinal disorder, or inflammation limited to another ocular structure. If the record does not clearly support bilateral involvement, check documentation.
Coding tip
Confirm both laterality and the word “unspecified” in the provider note before assigning H30.93.
