ICD-10 Code H30.043 – Focal chorioretinal inflammation, macular or paramacular, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.043 – Focal chorioretinal inflammation, macular or paramacular, bilateral
What it is
This code identifies focal inflammation affecting the choroid and retina in both eyes, centered in or near the macula. Use it when documentation specifies bilateral macular or paramacular involvement.
Clinical signs
Findings may include decreased central vision, blurred vision, or scotoma. Clinical features vary; refer to documentation for laterality, lesion location, and whether the inflammation is active.
When to use this code
Use H30.043 when the provider documents focal chorioretinal inflammation in both eyes with macular or paramacular involvement. It also fits ophthalmology notes that clearly describe bilateral lesions in the macular region. If the record does not specify both eyes or the exact location, check documentation before coding.
Do not use for
Do not use this code for unilateral disease, diffuse chorioretinitis, or other retinal disorders without choroidal inflammation. Check documentation if the note describes a different anatomic site or an unspecified inflammatory eye condition.
Coding tip
Verify bilateral laterality and macular or paramacular location in the provider note before assigning H30.043.
