Question: We used the EpiPen® kit in the office for a patient who experienced an allergic reaction to contrast dye. How do we bill for using this kit? Vermont Subscriber Answer: Use of an EpiPen® represents an injection of epinephrine. As such, it would be appropriate to code its administration using codes 96372 (Therapeutic, prophylactic, or diagnostic injection (specify substance or drug); subcutaneous or intramuscular) and J0171 (Injection, adrenalin, epinephrine, 0.1 mg).
