Benefit Category
Antigens
Note: This may not be an exhaustive list of all applicable Medicare benefit categories for this item or service.
Indications and Limitations of Coverage For antigens provided to patients on or after November 17, 1996, Medicare does not cover such antigens if they are to be administered sublingually, i.e., by placing drops under the patient's tongue. This kind of allergy therapy has not been proven to be safe and effective. Antigens are covered only if they are administered by injection.
