Clinical & Coding Specifications
Clinical Context
A patient diagnosed with chronic giant papillary conjunctivitis, such as in the right eye (H10.411), left eye (H10.412), or bilateral (H10.413), presents to an allergy and immunology clinic. The physician evaluates the patient and determines that allergen immunotherapy is indicated. The clinical workflow involves the physician supervising the preparation and provision of antigens for immunotherapy, which may include single or multiple antigens. The service is typically performed in an office or outpatient hospital setting, and may also occur in a skilled nursing facility if the physician is present. The physician ensures proper dosing and documentation of the number of doses prepared for the patient.
