ICD-10 Code H31.403 – Unspecified choroidal detachment, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.403 – Unspecified choroidal detachment, bilateral
What it is
H31.403 identifies choroidal detachment in both eyes when the type is not further specified. It means the choroid has separated from the underlying eye wall, but documentation does not define the cause or subtype.
Clinical signs
Clinical features vary; refer to documentation. Patients may have reduced vision, eye discomfort, or a shallow anterior chamber, and the finding is usually confirmed on ophthalmic examination or imaging.
When to use this code
Use this code when the provider documents bilateral choroidal detachment and does not specify serous, hemorrhagic, or another type. It also fits cases where both eyes are involved but laterality is clearly bilateral and no more detail is available. Check documentation if the record suggests a more specific diagnosis.
Do not use for
Do not use H31.403 if the record identifies a specific choroidal detachment type or only one eye is affected. Do not use it for retinal detachment or other posterior segment disorders.
Coding tip
Confirm both laterality and specificity in the ophthalmology note before assigning H31.403.
