ICD-10 Code H30.002 – Unspecified focal chorioretinal inflammation, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.002 – Unspecified focal chorioretinal inflammation, left eye
What it is
This code identifies a focal inflammatory disorder involving the choroid and retina in the left eye, when the exact cause or type is not specified. Use it when the record documents localized chorioretinal inflammation but not a more specific diagnosis.
Clinical signs
Findings may include localized ocular inflammation, reduced vision, floaters, or a visible chorioretinal lesion on exam or imaging. Clinical features vary; refer to documentation.
When to use this code
Use H30.002 when the clinician documents unspecified focal chorioretinal inflammation limited to the left eye. It is appropriate when the note confirms the location and laterality but does not identify a more specific infectious, inflammatory, or retinal condition.
If the documentation names a different chorioretinal disorder, code that condition instead. Check documentation when the diagnosis is uncertain or when both eyes are involved.
Do not use for
Do not use this code for chorioretinal inflammation in another eye or for a more specific chorioretinal diagnosis. Do not use it when the record only mentions nonspecific eye pain or blurred vision without documented inflammation.
Coding tip
Verify laterality and whether the provider documented focal chorioretinal inflammation specifically before assigning H30.002.
