ICD-10 Code H31.10 – Unspecified choroidal degeneration (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.10 – Unspecified choroidal degeneration
What it is
H31.10 identifies degeneration of the choroid, the vascular layer beneath the retina, when the type is not further specified. Use it when documentation confirms choroidal degeneration but does not name a more exact subtype.
Clinical signs
Clinical features vary; refer to documentation. Findings may include choroidal atrophy or other degenerative changes noted on eye examination or imaging, with associated visual complaints if recorded.
When to use this code
Use this code when the provider documents choroidal degeneration and does not specify a cause, laterality, or more detailed form. It is appropriate for nonspecific ophthalmology notes, problem lists, or assessment entries that clearly support degeneration of the choroid.
If the record names a different choroidal disorder, code that condition instead. When the note is vague, check documentation before assigning H31.10.
Do not use for
Do not use H31.10 for retinal disorders, chorioretinal inflammation, or choroidal conditions with a different specified diagnosis. Do not assign it when the chart supports a more precise code.
Coding tip
Code H31.10 only after confirming the provider meant choroidal degeneration and no more specific term is documented.
