- Allergy testing is covered when the medical record documents the test(s) used, the interpretation(s), and objective measurement of reaction size (wheal and erythema in mm) or a standardized in vivo grading system.
- Allergy testing is covered when the medical record contains documented history obtained prior to testing that indicates the possible presence of allergy.
- Allergy testing is covered when the history and examination show that attempts were made to narrow the area of investigation so that the minimal number of necessary skin tests will be performed.
- Allergy testing is covered when the selection of antigens for testing is explicitly based on the patient-specific history and physician or non-physician practitioner examination.
- Percutaneous prick/puncture (scratch, puncture, prick) skin testing is medically reasonable and necessary for evaluation of IgE-mediated hypersensitivity to inhalants, foods, Hymenoptera (stinging insects), chemicals, and specific drugs (e.g., penicillins, macromolecular agents).
