Medicare's Allergy Test Coverage: An Overview
In the year 2025, Medicare Part B and Medicare Advantage plans offer coverage for specific allergy tests under certain conditions. This article aims to provide a clear understanding of the tests covered, their purposes, and the necessary requirements for Medicare to foot the bill.
For individuals experiencing allergic reactions, Medicare covers blood testing procedures that measure antibodies in response to specific allergens. These tests, categorised under "clinical diagnostic laboratory tests," can help in managing or preventing allergy recurrences.
One such test is intradermal (intracutaneous) testing, which is covered by Medicare Part B when there are IgE-mediated allergic reactions suspected to any of the following categories: inhalants, stinging insects, specific drugs such as penicillins and macromolecular agents, and vaccines. This testing is considered medically necessary when ordered by a treating physician and used directly to manage a beneficiary’s specific medical problem.
Another test covered by Medicare is patch testing, which is the gold standard for diagnosing allergic contact dermatitis (ACD). Patch tests help physicians identify specific allergies by applying suspected allergens on the skin for 48 hours and subsequent readings.
To qualify for allergy testing under Medicare Part B, a person must have a documented history of allergic reactions and a history of significant symptoms that other therapies are unable to control. It is important to consult a physician before testing to ensure that a person's Medicare benefits plan will pay for a specific procedure.
Medicare Advantage plans, which are private insurance offered by Medicare-approved companies, typically cover the same Medicare-covered Part B allergy tests. However, coverage for new services added during the year 2025 may be subject to coinsurance (usually 20%).
Allergy treatment medications fall under Medicare Part D, the section that covers prescription drugs. A standard monthly premium applies for Original Medicare Part B, which is at least $185 in 2025, and an annual deductible, which is $257 in 2025. A person will usually pay 20% of the cost for each Medicare-covered service or item after paying the deductible.

- Health organizations should remind individuals with documented histories of allergic reactions that Medicare Part B covers specific blood testing procedures, which measure antibodies in response to allergens, to manage or prevent allergy recurrences.
- An allergist may perform intradermal testing, covered by Medicare Part B, to investigate suspected IgE-mediated allergic reactions to inhalants, stinging insects, specific drugs, or vaccines.
- Patch testing, the gold standard for diagnosing allergic contact dermatitis (ACD), is also covered by Medicare Part B when a treating physician orders it to identify specific allergies.
- Individuals seeking allergy testing under Medicare Part B must ensure they have significant symptoms that other therapies cannot control, and they should consult their physician before testing to confirm their Medicare benefits plan will pay for the specific procedure, especially when testing is subject to coinsurance under Medicare Advantage plans in 2025.
