Dr. Franklin must provide Joanie Howell with an Advance Beneficiary Notice, because rhinoplasty is not a Medicare covered service. An Advance Beneficiary Notice (ABN) is used when a healthcare provider believes that a particular service will not be covered by Medicare, giving the patient the option to decide whether to proceed with the service and accept financial responsibility if Medicare does not pay. Since rhinoplasty is typically considered a cosmetic procedure and not medically necessary, it falls under this category.
