ICD-10 Code H31.119 – Age-related choroidal atrophy, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.119 – Age-related choroidal atrophy, unspecified eye
What it is
This code identifies age-related thinning and atrophy of the choroid in an unspecified eye. Use it when the record documents this degenerative change but does not specify right or left eye.
Clinical signs
Findings may include choroidal atrophy noted on eye examination or imaging, often in an older patient. Clinical features vary; refer to documentation.
When to use this code
Use H31.119 when the clinician documents age-related choroidal atrophy and laterality is not stated. It also fits follow-up visits where the diagnosis remains active and no more specific eye is recorded. Check documentation if the note uses a broader retinal or macular diagnosis instead.
Do not use for
Do not use this code if the provider documents a different choroidal disorder or specifies right or left eye with a more exact code. Do not assign it when age-related choroidal atrophy is only suspected.
Coding tip
Verify laterality in the ophthalmology note before coding, because unspecified eye codes should be used only when the record does not identify the affected eye.
