Blepharophimosis left eye, unspecified eyelid

This code signifies a congenital malformation affecting the left eye, characterized by abnormally small palpebral fissures (the opening between the eyelids). It often involves ptosis (drooping of the upper eyelid) and epicanthus inversus (a fold of skin running from the lower eyelid to the inner canthus), leading to a narrowed appearance of the eye opening.

Apply this code when documentation specifies blepharophimosis affecting the left eye, without further detail regarding the specific eyelid involved (upper or lower). This diagnosis is typically made clinically based on characteristic facial features. Supporting documentation should clearly indicate the presence of blepharophimosis and laterality.

• Ensure documentation specifies "left eye" for accurate laterality.
• If the specific eyelid (upper or lower) is documented, a more precise subcategory code should be used.
• Consider co-reporting with codes for associated conditions like ptosis or epicanthus inversus if separately documented and clinically significant.
