Brown's sheath syndrome, right eye

This code describes Brown's sheath syndrome affecting the right eye, a congenital or acquired condition characterized by a restriction of the superior oblique tendon's movement through its trochlea. This restriction limits elevation of the affected eye, particularly when attempting to adduct (turn inward) the eye.

Use this code when documentation clearly indicates a diagnosis of Brown's sheath syndrome specifically impacting the right eye. This diagnosis is typically made based on clinical examination findings demonstrating impaired elevation in adduction of the right eye.

• Ensure laterality is accurately documented; this code is specific to the right eye.
• Distinguish from other causes of restricted eye movement, such as inferior oblique palsy or orbital floor fractures.
• Documentation should support the diagnosis through clinical findings or imaging if performed.
