CPT code 95028: Allergy skin testing, intradermal, delayed reaction2026 Medicare rate & RVUs

Medicare pays $12.36 for 95028 nationally in the office. Local office rates run $10.50–$17.52.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 95028 covers

Code 95028 represents intradermal allergy testing intended to detect a delayed-type response, rather than the immediate wheal-and-flare response assessed by routine immediate skin tests. The clinician introduces selected allergenic material into the skin and evaluates the response after the appropriate delay. Allergy and immunology clinicians commonly perform this testing in an outpatient office when a delayed hypersensitivity response is being investigated; the code is distinguished by both the intradermal route and delayed-response purpose, not merely by the fact that a result is read later.

Report the number of tests performed, with the record identifying the tested substances, intradermal placement, and delayed-response evaluation. Do not substitute 95024 for immediate-type intradermal testing, or 95044 when the procedure uses patch testing for contact sensitivity. CMS classifies 95028 as technical-component-only: it covers the testing procedure, while interpretation is represented by a separate code. Keep documentation for the procedure and the separately coded interpretation distinct; a delayed reading alone does not make an immediate-type test reportable as 95028.

How to choose

95024Intradermal allergy testImmediate reaction, allergenic extracts

Choose 95024 for intradermal allergenic-extract tests assessing immediate-type responses. Choose 95028 when the intradermal test evaluates a delayed-type response.

95044Patch testingEach separate patch test

95044 describes patch or application testing, rather than injecting test material intradermally. The route and testing method distinguish it from 95028.

95018Drug allergy testingPercutaneous and intracutaneous tests

95018 is for percutaneous and intradermal testing with drugs or biologicals for immediate-type reactions. 95028 is distinguished by its delayed-response purpose.
