What 95018 covers
An allergist or other qualified clinician uses percutaneous and/or intracutaneous testing to evaluate a suspected immediate hypersensitivity reaction to a drug or biological product. Testing may be considered when a medication allergy history needs clinical evaluation, such as before deciding whether a patient can receive a needed antibiotic. The code covers a combination of the two skin-test methods; it is specific to drugs and biologicals rather than environmental allergen extracts.
Report the number of tests performed, and retain documentation identifying the agents and test methods, the results, and the clinician’s interpretation and report. Interpretation and reporting are part of the service, rather than separate services for the same tests. Under the Medicare Physician Fee Schedule, payment is based on work, practice expense, and malpractice relative value units; the practice-expense valuation differs between office and facility settings.
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.

95018 billing questions
When should 95018 be chosen over 95017?
Use 95018 for drug or biological products. Code 95017 is the related testing code for venom allergy testing.
Can percutaneous and intracutaneous methods be reported together under 95018?
Yes. The code covers any combination of these methods for drug or biologic testing; report the number of tests performed.
Is interpretation separately billable?
Test interpretation and the report are included in 95018. Document the results and the clinician’s interpretation in the record.
What documentation supports the number of tests?
Record the drug or biological agents tested, the methods used, and the individual test results. The reported number should reflect the tests actually performed.
Is 95018 for environmental allergen testing?
No. It is for immediate-reaction testing with drugs or biologicals. Testing with allergenic extracts is represented by other allergy-testing codes, such as 95004 or 95024.
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.
