During a provider visit, if the provider deems allergy injections as a medical necessity for your treatment plan, you will be given a handout that includes ALL of the necessary CPT codes that we bill the insurance. We do ask our patients to contact their insurance company independently and supply them with the listed CPT codes that apply to them specifically to understand what the responsibility is on their part. This process helps all our patients better understand their specific benefits so there is not confusion as the allergy injection treatment can be up to a 5-year treatment sometimes.
