Anterior dislocation of lens, unspecified eye

This code signifies a condition where the crystalline lens of the eye has moved forward from its normal anatomical position, specifically into the anterior chamber. This displacement is not traumatic in origin and affects an unspecified eye.

Use this code when documentation clearly states an anterior dislocation of the lens without specifying a laterality (right or left eye) and without an identified traumatic cause. This code is appropriate for congenital or spontaneously occurring anterior lens luxation.

• Avoid using this code if the laterality is documented; instead, choose the more specific codes for right (H27.121) or left (H27.122) eye.
• Do not use this code if the dislocation is explicitly stated as traumatic; refer to codes in the T85.2- series for complications of prosthetic devices, implants, and grafts.
• Ensure the documentation specifies "anterior" dislocation; posterior dislocations are coded differently (H27.11-).
