ICD-10 Code H30.90 – Unspecified chorioretinal inflammation, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.90 – Unspecified chorioretinal inflammation, unspecified eye
What it is
This code identifies inflammation involving the choroid and retina when the eye is not specified. Use it when the record confirms chorioretinal inflammation but does not name a laterality or a more specific subtype.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include decreased vision, floaters, eye discomfort, or funduscopic evidence of chorioretinal inflammation.
When to use this code
Use H30.90 when the provider documents chorioretinal inflammation and does not identify the affected eye. It also fits when the note is nonspecific and no more detailed chorioretinal diagnosis is available. If laterality or a distinct condition is documented, code that instead.
Do not use for
Do not use this code for isolated retinal or choroidal disorders without chorioretinal inflammation. Also avoid it when the chart specifies a more precise diagnosis, such as a named chorioretinal disorder or laterality.
Coding tip
Check the ophthalmology note for laterality and the exact inflammatory diagnosis before defaulting to H30.90.
