CPT code 95133: Insect immunotherapy, four stinging insects2026 Medicare rate & RVUs in Texas

CMS doesn’t publish an office rate for 95133 in Texas.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
