This reminds me of how we were on a business trip in Denver back in 2016

I had to go to a quack in a box (walk in clinic) to get treatment for a sinus infection. It always goes into bronchitis if I don’t get treatment in time. Long story short … they have NEVER sent us a bill, never filed it with insurance either. We have Blue Cross and I never got an EOB. You would think they would want their money, either from me or BC. I know they had our correct address and made a copy of my ins. card. Oh well. Their loss.
