My wife had a decent chunk of medical debt when we got married which was long before COVID. Even at that time medical debt didn't count terribly against her. Maybe a 10 pt drop in her score. And eventually the debt fell off her credit.
Simply walking away from medical debt if there is only a minor impact on credit score seems like a decent option if not.
I did the same thing with an ER bill I couldn't afford a while back. I just never paid it and suffered virtually no consequences.
