What 95147 covers
95147 represents the allergy practice’s professional service for supervising preparation and provision of a treatment dose made with three distinct stinging insect venom extracts. It is used in venom immunotherapy, such as treatment for a patient whose prescribed regimen includes three venom types. An allergist or another qualified physician typically directs the service; trained practice staff may perform preparation under that supervision. The injection itself is a separate service from the antigen preparation and provision represented here.
Select this code by the number of venom types in the prepared dose, not by the number of injection sites or injections given. Keep records identifying the prescribed venoms, preparation and dose details, and the supervising professional. When an immunotherapy injection is administered, report the applicable injection service separately. CMS assigns this service substantially more office practice-expense value than physician-work value, with a much smaller facility practice-expense value.

95147 billing questions
When should 95147 be selected instead of 95146 or 95148?
Select 95147 when the prepared treatment dose contains three distinct stinging insect venoms. The neighboring codes represent doses with two or four venom types.

Document the three venom types in the prescribed preparation, the dose prepared or provided, and the professional supervision of the service.
How should units reflect the service?
Keep units tied to the treatment doses prepared and provided, supported by the practice’s dose and preparation records. Do not count injection sites as antigen-preparation units.

Yes, when the practice also administers an immunotherapy injection, the preparation/provision service and injection service describe distinct work. Choose the injection code based on the number of injections.
