What 95170 covers
CPT 95170 represents allergen immunotherapy using a whole-body extract, with the extract provided as part of the service. Allergy specialists commonly use this approach for whole-body insect extracts, such as fire-ant extract. The service is associated with the prescribing physician’s practice or institution and supports treatment under an established allergy immunotherapy plan.
Report units that match the whole-body extract service documented for the patient. Records should identify the extract and connect its preparation or provision to the prescribed immunotherapy. The code includes the extract, unlike 95165, which describes antigen services that exclude provision of allergenic extracts. CMS assigns physician work and practice expense values to 95170 under the physician fee schedule; the code’s included extract is not a separate supply service within this code.
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.

95170 billing questions
When should 95170 be chosen instead of 95165?
Use 95170 for allergen immunotherapy involving a whole-body extract that is provided as part of the service. Code 95165 is for antigen services that do not include provision of the allergenic extract.
Does 95170 include the allergenic extract?
Yes. The whole-body extract is part of the service represented by 95170.
Is 95170 counted by injection or by extract unit?
It is reported by unit for the whole-body extract service, not by counting the number of injections administered.
What documentation supports 95170?
Document the prescribed immunotherapy plan, the whole-body extract used, and the units provided. The record should make clear that the service involved a whole-body extract rather than a different antigen preparation.
How does 95170 differ from venom immunotherapy codes?
95170 is for whole-body extract immunotherapy. Codes such as 95145 identify antigen services for specific numbers of stinging-insect venoms.
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.
