What 95144 covers

An allergist or another qualified clinician supervises preparation and provision of patient-specific allergen extracts in single-dose vials for immunotherapy. The prescribed mixture may contain allergens such as pollens, dust mites, molds, or animal dander, selected for the patient’s allergy treatment plan. The service concerns preparing and supplying the treatment set, not giving an injection. It is typically furnished through an allergy practice for use in an outpatient immunotherapy program.

Report 95144 for the single-dose-vial preparation service, rather than for the number of injections administered. The record should support the prescribed allergens and formulation, the preparation and provision of the treatment set, and the patient for whom it was made. Injection administration is a distinct service; when it is performed, the applicable administration code reflects the number of injections given. For multiple-dose vial preparation, use the code that describes that vial format instead.

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.

95144 billing questions

How does 95144 differ from 95165?

95144 describes preparation and provision in single-dose vials. 95165 is used for preparation involving multiple-dose vial(s), so the vial format distinguishes the services.

Does 95144 include administering the allergy shot?

No. It represents supervised preparation and provision of the allergen treatment set. Report an applicable injection service when an injection is administered.

Can 95144 be reported with an injection code?

The preparation service and injection administration describe different work. If an injection is given, the applicable administration code may also describe that service.

What documentation supports 95144?

Document the patient-specific allergen prescription, the formulation prepared, and the preparation and provision of the single-dose treatment set.

Is 95144 appropriate for venom immunotherapy?

Use the venom-specific antigen preparation code when the service is for stinging insect venom. Code 95144 describes the single-dose-vial service for other allergen extracts.

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.
