Anterior dislocation of lens, bilateral

This code describes a condition where both natural lenses of the eyes have become displaced forward from their normal position within the globe, typically into the anterior chamber. This displacement can lead to significant visual impairment and potentially increased intraocular pressure.

Use this code when documentation clearly indicates an anterior dislocation of the crystalline lens in both eyes. This diagnosis is often supported by ophthalmological examination findings such as slit-lamp biomicroscopy showing the lens in the anterior chamber, and patient symptoms like sudden vision loss or eye pain.

• Ensure documentation specifies "anterior" dislocation; other types of lens displacement (e.g., posterior, subluxation) have different codes.
• Verify that the laterality is explicitly stated as "bilateral" to support this specific code.
• Consider co-reporting with codes for underlying causes (e.g., trauma, Marfan syndrome) or resulting complications (e.g., glaucoma) if documented.
