I have a general question and I'm hoping I will get a response. I have a physician that would like to bill for follow up visits in the hospital or a discharge with a modifier 24 when he has performed surgery on them. He is using a different diagnosis that is not related to the surgery. He is an orthopedic surgeon. He would like to link diagnosis such as Hypokalemia or idiopathic peripheral neuropathy, or severe malnutrition...etc. He is not actively treating the patient for these conditions, but is dictating something regarding these diagnosis in the hospital dictation. He is mainly seeing the patient for follow up on the surgery. Can he charge a follow-up or discharge after performing surgery on these patients?
