2026 ICD-10-CM Diagnosis Code H50.611 – Brown’s sheath syndrome, right eye
What it is
H50.611 identifies Brown’s sheath syndrome affecting the right eye. It is a restrictive eye movement disorder that limits normal upward movement, especially when the eye is turned inward.
Clinical signs
Typical findings include limited elevation in adduction and a mechanical restriction on examination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents Brown’s sheath syndrome in the right eye or equivalent wording for that eye. Code it from the ophthalmology assessment, operative note, or specialist diagnosis. If laterality is not stated, check documentation before assigning this code.
Do not use for
Do not use this code for unspecified Brown syndrome, left eye, or bilateral disease. Do not apply it to general strabismus or other causes of limited eye movement unless Brown’s sheath syndrome is clearly documented.
Coding tip
Always verify laterality and the exact provider wording before selecting H50.611.
