ICD-10 Code H51.12 – Convergence Excess (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H51.12 – Convergence excess
What it is
Convergence excess is an eye alignment disorder where the eyes turn inward too much when focusing on near objects. It can cause discomfort or difficulty maintaining clear, single vision at close range.
Clinical signs
Common findings include inward eye deviation that is greater at near than at distance and symptoms during reading or other close work. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents convergence excess, convergence excess esotropia, or a similar near-vision alignment problem. It may also apply when the record clearly describes excessive inward turning of the eyes at near fixation. Check documentation if the note is nonspecific.
Do not use for
Do not use this code for general blurred vision, unspecified strabismus, or eye strain without documented convergence excess. If the chart does not identify the condition, code the documented finding instead.
Coding tip
Code from the provider’s exact diagnosis wording, and confirm whether the problem is specifically greater at near than at distance.
