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.

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.

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.

Does 95147 include administering the injection?

No. It represents supervision of antigen preparation and provision; report the appropriate immunotherapy injection service separately when an injection is administered.

What documentation supports 95147?

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.

Can 95147 be reported with an injection code?

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.

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.
