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.
