Results will likely vary by population and geography but there's a good chance claims are lower all-in for many groups, especially younger ones away from big cities. For 2-3 months all steps are being made to clear out non-essential care. Some unnecessary back surgeries will never show up in claims now, a sort of forced 2nd opinion. ER visits have dropped as well. Hospitalization rates for Corona tend to be much higher for >65. CDC site shows hospitalizations per 100,000 for end of March at under 2-7 for 18-64 but these numbers change each week. CDC data here. Social distancing, hand washing, masks, etc are showing their fruits.
