ICD-10 Code H31.112 – Age-related choroidal atrophy, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.112 – Age-related choroidal atrophy, left eye
What it is
This code identifies age-related thinning and degeneration of the choroid in the left eye. It is used when the record specifically documents age-related choroidal atrophy affecting that eye.
Clinical signs
Findings may include choroidal atrophy noted on ophthalmic examination or imaging. Clinical features vary; refer to documentation.
When to use this code
Use H31.112 when the provider documents age-related choroidal atrophy in the left eye. This is appropriate for ophthalmology notes, imaging reports, or problem lists that clearly identify the left eye.
If the chart only mentions choroidal changes without laterality or age-related cause, check documentation before coding. Do not assume the condition applies to both eyes.
Do not use for
Do not use this code for unspecified choroidal disease, non-age-related atrophy, or conditions documented in the right eye or both eyes. Check documentation.
Coding tip
Confirm laterality and the age-related diagnosis in the provider note before assigning H31.112.
