ICD-10 Code H31.113 – Age-related choroidal atrophy, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.113 – Age-related choroidal atrophy, bilateral
What it is
H31.113 identifies age-related thinning and degeneration of the choroid in both eyes. Use it when documentation specifically states bilateral age-related choroidal atrophy.
Clinical signs
Findings may include bilateral choroidal atrophy noted on eye examination or imaging. Clinical features vary; refer to documentation for the exact ophthalmic findings recorded.
When to use this code
Use this code when the provider documents age-related choroidal atrophy affecting both eyes. It may appear in ophthalmology notes, retinal imaging reports, or problem lists. Code only when the bilateral diagnosis is explicit.
Do not use for
Do not use this code if the record describes unilateral disease or another choroidal disorder without age-related atrophy. Check documentation if the chart uses nonspecific retinal or choroidal degeneration terms.
Coding tip
Verify laterality carefully; H31.113 is for bilateral disease only.
