ICD-10 Code H53.31 – Abnormal Retinal Correspondence (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.31 – Abnormal retinal correspondence
What it is
Abnormal retinal correspondence is a binocular vision condition where the eyes do not match images in the usual way. Use this code when documentation identifies this specific sensory adaptation.
Clinical signs
Findings may include unusual binocular responses, suppression, or atypical sensory fusion on eye testing. Clinical features vary; refer to documentation.
When to use this code
Use H53.31 when the provider documents abnormal retinal correspondence as the diagnosis or an established finding. It may appear in strabismus or amblyopia evaluations, but you should code only when the record clearly names this condition.
Do not use for
Do not use this code for generic blurred vision, diplopia, or unspecified binocular vision problems. Check documentation if the note describes strabismus without confirming abnormal retinal correspondence.
Coding tip
Assign H53.31 only when the chart explicitly supports abnormal retinal correspondence, not when it is merely suspected.
