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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

95028 billing questions

How does 95028 differ from 95024?

95028 is for intradermal testing directed at delayed-type responses. 95024 is for intradermal tests assessing immediate-type reactions.

Is interpretation included in 95028?

No. CMS identifies 95028 as technical-component-only, with interpretation covered by a separate code.

How should the test count be documented?

Identify the substances tested and document the number of intradermal tests performed. A later reading is not a separate test.

When is 95044 a better fit?

Use 95044 for patch or application testing, commonly used to evaluate contact sensitivity. Use 95028 when the testing method is intradermal and the response being evaluated is delayed-type.

Does an immediate test reported later become 95028?

No. Code selection follows the response type the test is designed to assess, not simply when the result is read.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
