Per the CPT book, the patient cannot receive any "professional" services from the physician/qualified health care professional of the exact same specialty and subspecialty in the same group practice within the past three years.
If the patient has only received allergy injections in the last 4 years in a specific office would it be appropriate to allow a new patient E&M? Or, are the allergy injections considered a professional service even if provided by a nurse or PA?
