Squamous blepharitis left upper eyelid

This code signifies inflammation of the left upper eyelid margin, specifically characterized by squamous blepharitis. This condition involves scaling and flaking along the eyelid, often associated with chronic irritation and bacterial overgrowth.

Apply this code when documentation clearly indicates squamous blepharitis affecting the left upper eyelid. This diagnosis is typically supported by findings of scales, crusts, or erythema along the eyelid margin, localized to the specified area.

• Ensure laterality (left) and specific eyelid (upper) are explicitly documented.
• Distinguish from other forms of blepharitis, such as ulcerative or seborrheic, which have different ICD-10-CM codes.
• Code any underlying causes or associated conditions, such as rosacea or dry eye, if documented.
