Blepharochalasis left eye, unspecified eyelid

This code describes a condition characterized by recurrent swelling of the left upper eyelid, leading to stretching and thinning of the skin, often resulting in redundant folds. It is a rare disorder primarily affecting the upper eyelids, causing an "aged" appearance and potentially impairing vision.

This code is appropriate for documenting blepharochalasis specifically affecting the left eye when the specific eyelid (upper or lower) is not documented. Clinical documentation should clearly state the diagnosis of blepharochalasis and specify the left eye involvement.

• Do not use this code if the laterality is unspecified or if both eyes are affected; use the appropriate unspecified or bilateral code.
• Ensure documentation differentiates blepharochalasis from dermatochalasis, which is age-related redundant eyelid skin.
• If the specific eyelid (upper or lower) is documented, use the more specific code (H02.31- or H02.34-).
