What 95133 covers

Code 95133 identifies allergen immunotherapy associated with four stinging insects. It is part of the stinging-insect immunotherapy series, whose neighboring codes distinguish other insect counts. Allergy specialists commonly manage this treatment for patients with reactions to insect stings. Selection follows the number of stinging-insect allergens addressed, rather than the number of injections given.

Medicare classifies 95133 as status I, meaning the code is not valid for Medicare; Medicare uses a different code to report and pay for the service. Do not submit 95133 to Medicare as the service code. In the 95130–95134 series, choose the sibling matching the number of stinging insects involved: one, two, three, four, or five. The four-insect count is the distinguishing feature of 95133.

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.
