Convergence insufficiency

This code represents a specific type of exophoria characterized by an inability to maintain binocular alignment for near vision tasks. Patients typically experience symptoms such as asthenopia, diplopia, and blurred vision when reading or performing close work due to the eyes' difficulty turning inward sufficiently.

Use this code for patients diagnosed with convergence insufficiency based on objective findings during an ophthalmic examination, such as a receded near point of convergence and reduced positive fusional vergence. Documentation should clearly state the diagnosis and supporting clinical findings.

• Differentiate from other forms of exophoria; this code is specific to insufficiency of convergence.
• Ensure documentation specifies "insufficiency" rather than a general exophoria, which would lead to a different code.
• Consider sequencing with codes for associated symptoms like asthenopia (H53.1x) if documented as separate conditions.
