ICD-10 Code H30.009 – Unspecified focal chorioretinal inflammation, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.009 – Unspecified focal chorioretinal inflammation, unspecified eye
What it is
This code identifies a focal inflammatory disorder involving the choroid and retina in an unspecified eye. Use it when documentation confirms chorioretinal inflammation but does not specify laterality or a more exact subtype.
Clinical signs
Findings may include decreased vision, floaters, or a localized retinal-choroidal inflammatory lesion on examination. Clinical features vary; refer to documentation.
When to use this code
Use H30.009 when the record states focal chorioretinal inflammation and the eye is not identified as right or left. It also fits when the provider documents chorioretinal inflammation without enough detail for a more specific code. Check documentation if another infectious, autoimmune, or traumatic cause is named.
Do not use for
Do not use this code for generalized chorioretinal inflammation, clearly laterality-specific cases, or conditions with a more specific diagnosis. Do not assign it when the chart only mentions retinal disease without chorioretinal involvement.
Coding tip
Confirm both the inflammatory site and laterality before coding, because unspecified eye codes are appropriate only when the record lacks that detail.
