What 95131 covers

95131 identifies a venom-allergy immunotherapy visit involving two stinging-insect venoms. An allergy specialist reports it for treatment administered during a patient's care for insect-venom allergy. The code distinguishes the visit by the number of venoms addressed, rather than by the count of injections. It is separate from codes describing preparation and provision of allergen extracts.

Medicare assigns status I to 95131: Medicare does not accept this CPT code and uses a different code to report and pay for the service. Within the CPT venom-immunotherapy family, the neighboring codes distinguish visits by the number of stinging-insect venoms involved. Antigen preparation and provision are represented separately from the venom-immunotherapy visit.

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.
