Allergy services
Reports allergist-supervised preparation and provision of allergen immunotherapy antigens for treatment plans involving two distinct stinging-insect venoms.
An allergist or allergy practice reports this service for the professional supervision involved in preparing and providing immunotherapy antigens for two distinct stinging-insect venoms. It concerns the venom extracts supplied for a patient’s desensitization regimen, not the injection visit itself. The service is typically part of outpatient allergy care, with the treating allergist determining the venom immunotherapy plan and the practice preparing or arranging the prescribed extracts.
Choose this code when the preparation and provision service covers two venom types; the count is based on venoms, not injection sites or the number of shots given. Documentation should identify the prescribed venom immunotherapy and support that two distinct venoms were prepared or provided. This code represents antigen preparation and provision, so it should not stand in for the separate service of administering venom injections. CMS facts supplied for this code list no additional payment rules.
