A 61-year-old established patient with severe RA comes in for a scheduled methotrexate injection and infliximab infusion; 600 mg of infliximab is set aside and mixed. The patient is injected with 15 mg of methotrexate. The patient also has a detailed problem history, a detailed examination, and a medical decision-making of moderate complexity due to a complaint of fatigue and joint pain. Thirty-five minutes into the infusion, the patient has a reaction to the infliximab. The infusion is discontinued after 200 mg of infliximab is infused, and an intravenous injection of methylprednisolone sodium succinate, 40 mg, is given. IV hydration of saline is continued for forty minutes to flush out the infliximab. All documentation is noted appropriately. How do you code for correct reimbursement?
