Vernal keratoconjunct, w limbar and corneal involv, r eye

This code signifies a severe, chronic, bilateral allergic inflammatory condition of the conjunctiva and cornea, specifically affecting the right eye. It is characterized by the presence of limbal and corneal involvement, indicating more advanced disease than simple conjunctival inflammation. This condition is often seasonal and typically affects children and young adults.

Use this code when documentation clearly indicates vernal keratoconjunctivitis with specific involvement of the limbus and cornea in the patient's right eye. This diagnosis is typically made by an ophthalmologist based on characteristic clinical findings such as Trantas dots (limbal papillae) and shield ulcers (corneal involvement). Documentation should specify the laterality and the presence of both limbal and corneal manifestations.

• Ensure documentation explicitly states "right eye" and confirms both limbal and corneal involvement.
• Differentiate from other forms of allergic conjunctivitis that do not have limbal or corneal involvement.
• Do not use if only conjunctival involvement is noted; a different subcategory would apply.
