Vernal keratoconjunct, w limbar and corneal involv, bi

This code signifies a chronic, severe allergic eye condition affecting both eyes, characterized by inflammation of the conjunctiva and cornea, specifically involving the limbus. It is a recurrent, seasonal form of conjunctivitis often associated with atopy.

Apply this code when documentation specifies bilateral vernal keratoconjunctivitis with clear involvement of both the limbus and cornea. Supporting documentation would include ophthalmologist notes detailing these specific anatomical sites of involvement in both eyes.

• Ensure documentation explicitly states "bilateral" involvement and specifies both "limbar" and "corneal" involvement.
• Do not use this code if only conjunctival involvement is noted, or if the involvement is unilateral.
• Consider sequencing this code with codes for associated allergic conditions, such as asthma or eczema, if documented.
