Anterior dislocation of lens, left eye

This code signifies a condition where the crystalline lens of the left eye has completely dislodged from its normal position and moved forward into the anterior chamber. This displacement can obstruct aqueous humor outflow and potentially damage the corneal endothelium.

Apply this code when documentation explicitly states an anterior dislocation of the lens in the left eye. This typically occurs following trauma, but can also be spontaneous in cases of zonular weakness or Marfan syndrome. Supporting documentation should include ophthalmological examination findings confirming the anterior displacement.

• Differentiate from subluxation (partial displacement) or posterior dislocation.
• Always specify laterality (left, right, or bilateral) as documented.
• Code any underlying cause (e.g., trauma, systemic disorder) as a primary or secondary diagnosis.
