Jimmie,
If that works more broadly than Medicare, it may be the answer. Our closest analogy is a patient who wants an annual comprehensive exam done and either a flight physical or CDL medical at the same time. Since neither of those services is paid for by insurance, we charge an "add-on" fee that is billed directly to the patient, not using a CPT code at all. My concern from your description, however, is that with the blossoming of preventive health requirements and the complexity of many of our patients, adding a 99213 won't come very close to covering the total time spent r work done. I'll have to think about this more. Thanks for the input.
