Allergy testing

About 95004: Percutaneous allergy skin testing, immediate reaction

Percutaneous scratch, prick, or puncture testing with allergenic extracts evaluates immediate allergic reactions and is reported for each individual test performed.

Allergists, otolaryngologists, and some primary care clinicians perform percutaneous testing to evaluate suspected immediate allergies, including allergic rhinitis, asthma triggers, and food allergy. Small amounts of allergenic extract are introduced through a scratch, prick, or puncture on the forearm or back. The resulting wheal and flare are read shortly afterward. Typical extracts include pollens, dust mites, animal dander, molds, and foods. Clinical staff may apply and read the tests under physician supervision; interpretation and a report are included in the service.

Report one unit for each individual percutaneous test performed, rather than one unit for the panel. Document the extracts, controls, test sites, reactions, read time, and interpretation to support the reported count. When clinically indicated, separately performed intradermal immediate-reaction tests with allergenic extracts are reported with 95024 and their own test count. Do not bill separately for the interpretation of 95004. A significant, separately identifiable office evaluation on the same date may be reported with an appropriate E/M code and modifier 25 on the E/M service.

95004 billing questions

How many units of 95004 are reported for a skin test panel?

Report one unit per individual percutaneous test performed, not one unit for the panel. The record should identify the tested extracts so the count can be verified.

Can 95004 and 95024 be billed on the same day?

Yes, when both percutaneous and clinically indicated intradermal immediate-reaction testing with allergenic extracts are performed. Report each code with its own test count and document which extracts received each method.

Should 95004 be used for insect venom or drug allergy testing?

Use 95017 for stinging insect venom testing and 95018 for drug or biological testing. Those codes cover percutaneous testing, intradermal testing, or a combination, as performed.

Is the physician interpretation billed separately?

No. Interpretation and reporting of the skin test results are included in 95004. A significant, separately identifiable E/M service may be reported with modifier 25 on the E/M code.

What documentation supports 95004?

Record the extracts and controls, percutaneous method, test sites, wheal and flare measurements or grading, read time, and interpretation. The documented tests should support the number of units billed.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
