Squamous blepharitis right upper eyelid

This code describes inflammation of the right upper eyelid margin characterized by squamous (scaly) debris. It indicates a specific type of blepharitis affecting a particular eyelid.

Use this code when documentation specifies squamous blepharitis impacting the right upper eyelid. This diagnosis is typically supported by an ophthalmological exam noting scaly deposits and inflammation along the eyelid margin.

• Ensure the documentation clearly specifies "squamous" blepharitis and the exact eyelid (right upper).
• Differentiate from ulcerative or other forms of blepharitis, which have distinct codes.
• Do not use if the blepharitis is unspecified as to type or laterality.
