Subluxation of lens, right eye

This code signifies a partial displacement of the crystalline lens from its normal position within the right eye. This displacement can be congenital or acquired, often resulting in visual disturbances such as monocular diplopia, astigmatism, or reduced visual acuity. The zonular fibers supporting the lens are either stretched or partially ruptured.

Use this code when documentation clearly indicates a subluxation of the lens specifically affecting the patient's right eye. This diagnosis is typically made during an ophthalmological examination, often supported by slit-lamp findings showing an eccentric or tilted lens. It is appropriate for both traumatic and non-traumatic causes of lens subluxation.

• Differentiate from complete dislocation (luxation) of the lens, which involves total displacement from the pupillary aperture.
• Ensure laterality is explicitly documented; do not default to unspecified if the right eye is clearly affected.
• Consider additional codes for underlying causes, such as trauma (e.g., S05.01XA for injury to conjunctiva and corneal abrasion without mention of foreign body, right eye) or systemic conditions (e.g., Marfan syndrome).
