Subluxation of lens, left eye

This code signifies a partial dislocation of the crystalline lens within the left eye, meaning the lens is displaced from its normal position but remains partially attached to the ciliary body. This can lead to visual disturbances such as monocular diplopia, reduced visual acuity, or astigmatism.

Use this code when documentation clearly indicates a subluxation of the lens specifically affecting the left eye. This diagnosis is often associated with trauma, systemic disorders like Marfan syndrome, or pseudoexfoliation syndrome. Supporting documentation should include ophthalmological examination findings confirming the partial displacement.

• Ensure laterality is precisely documented and coded; distinguish between left, right, and bilateral subluxation.
• Differentiate subluxation from complete dislocation (luxation), which would require a different code.
• Look for underlying causes or associated conditions that may also need to be coded, such as trauma or systemic syndromes.
