There was a big dip in 2021, but it has started rising again, and it's possible it might rendezvous again with the old trend. This means parent-poster might be technically correct in the sense of "between T to T+3 it decreased", but I would not jump straight to blaming the the longer-term background horribleness of US health insurance for it.
It's far more likely to be that teensy-weensy COVID-19 pandemic, both in terms of direct damage and also reduced care for everything else.
