ICD-10 Code H30.00 – Unspecified focal chorioretinal inflammation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.00 – Unspecified focal chorioretinal inflammation
What it is
This code identifies a localized inflammatory condition involving the choroid and retina, without a more specific type named in the record. Use it when documentation says focal chorioretinal inflammation but does not define the cause or subtype.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include localized retinal or chorioretinal inflammation noted on eye examination, with symptoms such as blurred vision, floaters, or visual disturbance if recorded.
When to use this code
Use H30.00 when the provider documents unspecified focal chorioretinal inflammation and no more precise diagnosis is available. It also fits cases where the note confirms focal chorioretinal inflammation but does not identify an infectious, inflammatory, or other specific cause.
If the record later specifies a different chorioretinal disorder, code that diagnosis instead. Check documentation when the location, laterality, or underlying etiology is unclear.
Do not use for
Do not use this code for generalized chorioretinal inflammation, isolated retinal disease, or choroidal disorders without retinal involvement. Also avoid it when the chart gives a more specific chorioretinal diagnosis.
Coding tip
Code the most specific chorioretinal diagnosis documented; if the note only says “unspecified focal chorioretinal inflammation,” H30.00 is appropriate.
