Angular blepharoconjunctivitis, right eye

This code signifies an inflammatory condition affecting both the conjunctiva and the eyelids, specifically at the outer or inner corners (canthi) of the right eye. It is characterized by redness, irritation, and often maceration or scaling of the skin at the angles of the eyelids, accompanied by conjunctival inflammation.

Use this code when documentation specifies angular blepharoconjunctivitis affecting the right eye. Supporting documentation should detail the location of the inflammation (angular/canthal region) and confirm involvement of both the conjunctiva and eyelids. This diagnosis is often associated with bacterial infections, particularly Moraxella lacunata.

• Ensure documentation clearly specifies "angular" involvement to differentiate from other forms of blepharoconjunctivitis.
• Laterality is crucial; confirm the right eye is affected.
• Consider coding an additional code for the causative organism if identified and documented.
