ICD-10 Code H31 – Other disorders of choroid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31 – Other disorders of choroid
What it is
H31 identifies choroidal conditions that do not fit a more specific ICD-10 category. The choroid is the vascular layer beneath the retina, and this code captures other documented disorders of that structure.
Clinical signs
Clinical features vary; refer to documentation. Findings may include choroidal abnormalities noted on eye exam, imaging, or specialist assessment, but the exact disorder should be stated when available.
When to use this code
Use H31 when the provider documents a choroidal disorder that is not described by a more specific code. It is appropriate when the record clearly identifies the choroid as the affected structure and no better ICD-10 option is given. Check documentation for the exact diagnosis.
Do not use for
Do not use this code for retinal, vitreous, or optic nerve disorders. If the chart names a specific choroidal condition with its own code, report that more specific code instead.
Coding tip
Code the most specific choroidal diagnosis documented; use H31 only when no more detailed code applies.
