Other chronic allergic conjunctivitis

This code signifies a persistent inflammation of the conjunctiva due to an allergic reaction, excluding acute forms and those specifically categorized elsewhere. It represents a long-standing, non-infectious irritation of the eye's surface caused by allergens.

Apply this code when documentation indicates a patient presents with chronic allergic conjunctivitis that is not otherwise specified as atopic, vernal, or other specific types. This code is appropriate when the physician's diagnosis explicitly states "other chronic allergic conjunctivitis" or when clinical notes describe persistent allergic conjunctivitis without further specific classification.

• Ensure the documentation clearly specifies "chronic" and "allergic" to differentiate from acute or non-allergic conjunctivitis.
• Avoid using this code if a more specific type of chronic allergic conjunctivitis (e.g., atopic, vernal) is documented; refer to codes H10.40-H10.44.
• Always code the laterality (right, left, or bilateral) if specified in the medical record.
