ICD-10 Code H31.8 – Other specified disorders of choroid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.8 – Other specified disorders of choroid
What it is
H31.8 identifies a choroidal disorder that is specified in the record but does not fit a more exact ICD-10-CM choroid code. Use it when the provider documents a distinct choroid condition without a better listed option.
Clinical signs
Clinical features vary; refer to documentation. Findings may include choroidal abnormalities noted on eye exam, imaging, or specialist assessment, but the exact presentation depends on the underlying disorder.
When to use this code
Use H31.8 when the ophthalmology note names an unusual or otherwise specified choroidal disorder and no more specific code is available. It is appropriate only when the diagnosis is clearly documented and the record does not support a different choroid code.
If the provider writes a broad eye complaint without a choroidal diagnosis, do not assign this code. Check documentation for laterality, cause, or a more specific disorder before selecting H31.8.
Do not use for
Do not use H31.8 for general retinal disease, nonspecific visual symptoms, or choroid conditions that have a dedicated ICD-10-CM code. If the diagnosis is uncertain, check documentation.
Coding tip
Code H31.8 only after confirming the provider documented a specific choroid disorder and no more precise code applies.
