Is there a HCPC code for Dupixent? I have a provider that administered a Dupixent injection as the patient had originally went to the pharmacist but the pharmacist was not able to administer the drug. The patient tried to do it herself but was unsuccessful. She returned to the clinic and had the provider administer the injection. The Provider is billing a EM 99214 in addition 11900 and 96372. Does any one know if this is correct?
