Blepharochalasis left upper eyelid

This code signifies a chronic, recurrent edema of the upper eyelid, specifically affecting the left eye, which results in stretching and atrophy of the eyelid skin. It is characterized by thin, wrinkled, and redundant skin that can hang over the eyelid margin.

Apply this code when documentation explicitly states blepharochalasis of the left upper eyelid. This diagnosis is typically made based on clinical examination revealing characteristic skin changes and may be supported by patient history of recurrent eyelid swelling.

• Ensure laterality is clearly documented (left, right, or bilateral) to select the most specific code.
• Differentiate from dermatochalasis, which is age-related skin laxity, not recurrent edema.
• Code any associated functional impairment (e.g., visual field defect) separately if documented.
