Yet another stupid insurance issue, this is so bad

Another cry for single payer. Just got a late bill, that I did not remember ever seeing prior. Small bill $50.00, but did not recognize the provider. Go to my insurance web site, see a bill for the exact same amount, but again different provider. Neither the bill, or web site gave the date of service, or an “English” translation of what it was. Call the provider to inquire, when and what. Well it was a mammogram follow up (its all good). Here come my questions.

I had this done at X so why a bill from Y. Well the radiologist we used was out of network.

My next question. This is part of well woman, so why is it not covered that way. Well she (your Doctor) ordered just a B procedure/image. Me, I had a mammogram, yes but she only wanted the B angle on your right breast, so its not a well woman mammogram, it is a separate test. A mammogram would be A,B,C,D,E images of both breasts. Me, so what your saying is if I had had a full series of images of both breasts, rather than just a few images of one breast from a specific angle it would be covered. An image that would have be captured in any regular mammogram? In other words if I had a full series, used up more of the tech’s time, used more computer memory (digital images), used more energy and time on the machine causing it to need maintenance sooner, it would be covered, but because only one image (the iffy one from my prior visit), was requested I get to pay. The answer was yes. So what have I learned, if this happens again, to waste everyones time and money and get the full set of images done to save me $50.00. This is such a waste of everyones time and MONEY.
