I'd highly recommend checking out the linked dataset.[1] One quick observation: subtract Average Covered Charges from Average Total Payments and sort to see what procedures are most overcharged: 7 of the top 10 are "207 - RESPIRATORY SYSTEM DIAGNOSIS W VENTILATOR SUPPORT 96+ HOURS". Average overcharge among those top records is 601K. What is going on that they routinely charge 601K more than they collect? I'm excited to see what all everyone else comes up with.
