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.
