Clinical & Coding Specifications
Clinical Context
A 34-year-old patient with seasonal allergic rhinitis presents to an allergy clinic for initiation of allergen immunotherapy. The allergist reviews skin testing and specific IgE results, selects relevant allergen extracts (e.g., grass pollen, tree pollen, and dust mite), and prepares individualized single-dose vials for subcutaneous injection. The clinical workflow includes: obtaining informed consent, verifying allergen selection and concentrations, using aseptic technique to mix and dilute antigens per clinic protocol and manufacturer guidelines, labeling single-dose vials with patient identifiers and concentration, and documenting lot numbers, expiration dates, and amounts prepared in the medical record. The preparation occurs in a procedure room or pharmacy area within the clinic prior to administration; billing uses 95144 when the provider prepares one or more single-dose vials for that patient on the same date of service.
