There is actually credible evidence that it's way more than $95B medicare fraud. There is an interesting introduction into the issue by a YT called Coffeezilla [1] and there is an interesting effort by the folks at Effort.news [2] the are getting access to government data and working out just how much fraud and waste there is.

It seems to blow people's minds to accept things like "how can there be $100B in medicare fraud alone every single year", but that's really just what the government even roughly admits to or can easily identify because it is so blatant that they can't ignore it, not even some of the other obvious stuff that Coffeezilla talks about that should be blatantly obvious to the point that SWAT teams are sent in immediately (like the two top billing companies for certain medicare treatments being based in the same strip-mall, right next to each other and both being empty/vacant).
