What 95145 covers

An allergist or allergy practice reports this service for supervising preparation and provision of a single stinging-insect venom antigen used in immunotherapy. A typical case is venom treatment for a patient with a systemic reaction to a specific insect sting, such as a honeybee or yellow jacket. This code represents the antigen service, not the injection itself.

Select the one-venom level based on the antigen supplied, and report units for the doses prepared and provided rather than the number of injections administered. Documentation should identify the venom antigen, the dose quantity prepared or supplied, and the immunotherapy plan. CMS values the service under the physician fee schedule using work, practice expense, and malpractice RVUs; its practice-expense allocation is much higher in the office setting than in a facility.

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.

95145 billing questions

When is 95145 used instead of 95146?

Use 95145 for one single stinging-insect venom antigen. Use 95146 when the preparation and provision covers two single venoms.

Are units based on injections or doses?

Units represent doses of antigen prepared and provided, not the number of injections administered. Keep the dose quantity supported by the preparation and supply record.

Does 95145 report the injection?

No. It reports supervision of antigen preparation and provision. Injection services are represented by separate immunotherapy service codes when applicable.

What documentation supports this code?

Record the specific venom antigen, the number of doses prepared or supplied, and the patient's immunotherapy plan. The record should support why the one-venom level was selected.

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.
