An annual screening mammogram is automatically covered. If it’s a “diagnostic” mammogram following up some specific issue or complaint, then it would then fall into whatever normal policy rules you have with your insurance company for imaging tests. That’s more likely the case here since this person had to go on to have an ultrasound as well.
If you have insurance but get billed for an annual screening mammogram, it’s possible it was coded improperly by billers and you should definitely check up on that before paying.
This is bizarre, I looked and Rochester Minnesota has multiple high speed providers, including two that offer fiber.
And the isp you have is a wireless isp that doesn’t even list Rochester as within its coverage area, they’re intended to serve more rural areas west of the city. On their map it gets close to but not quite in Rochester, but maybe they’re still able to access it (slowly) since it’s a wireless provider.
I’m guessing this is a whoever owns your Airbnb problem rather than a Rochester Minnesota problem. I don’t understand why they would be paying for this rather than use any of the readily available high speed options there.
