    "description": "An MRI of the abdomen performed both before and after an intravenous contrast agent is given. Running both phases lets the radiologist watch how a lesion takes up and washes out contrast over time, which is often the deciding evidence for what it is - a benign hemangioma and a worrying tumor can look similar on a single snapshot but behave differently across phases. MRI of the abdomen done plain only, or with contrast only, is coded separately.",

        "question": "How much did Medicare pay for CPT 74183 in Q2 2018?",
