ICD-10 Code H31.11 – Age-related choroidal atrophy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.11 – Age-related choroidal atrophy
What it is
H31.11 identifies age-related thinning and degeneration of the choroid, the vascular layer beneath the retina. Use it when the record specifically documents age-related choroidal atrophy.
Clinical signs
Clinical features vary; refer to documentation. Findings may include choroidal thinning noted on eye examination or imaging, often in the setting of age-related retinal changes.
When to use this code
Use this code when the provider diagnoses age-related choroidal atrophy as the reason for the visit or as an established condition. It is appropriate when documentation clearly links the choroidal atrophy to age-related degeneration. Check the note if the record only mentions nonspecific retinal or choroidal changes.
Do not use for
Do not use H31.11 for other choroidal disorders, inflammatory disease, or trauma-related choroidal damage. If the chart does not state age-related choroidal atrophy, check documentation.
Coding tip
Code only when the diagnosis is explicitly documented; “choroidal thinning” alone may not be enough.
