What 95146 covers
An allergist or allergy practice reports this service for the professional supervision involved in preparing and providing immunotherapy antigens for two distinct stinging-insect venoms. It concerns the venom extracts supplied for a patient’s desensitization regimen, not the injection visit itself. The service is typically part of outpatient allergy care, with the treating allergist determining the venom immunotherapy plan and the practice preparing or arranging the prescribed extracts.
Choose this code when the preparation and provision service covers two venom types; the count is based on venoms, not injection sites or the number of shots given. Documentation should identify the prescribed venom immunotherapy and support that two distinct venoms were prepared or provided. This code represents antigen preparation and provision, so it should not stand in for the separate service of administering venom injections.

95146 billing questions
How is this code distinguished from 95145 or 95147?
This code is for antigen preparation and provision involving two stinging-insect venoms. Use 95145 for one venom and 95147 for three.
Does this code include the venom injection?
No. It represents supervision of venom antigen preparation and provision, not administration. When injections are given, the applicable injection service is selected separately.
How should the venom count be determined?
Count the distinct stinging-insect venoms represented in the prepared or provided immunotherapy antigens. The code covers two venom types, not two injections.
Is this the right code for nonvenom allergy extracts?
No. This code is for stinging-insect venom antigens. Code 95165 is used for preparation and provision of nonvenom allergen antigens.
What documentation supports reporting this service?
The record should support the prescribed venom immunotherapy and identify the two distinct venom antigens prepared or provided for the patient.
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.
