No, ACA has rules for breast screening coverage. If it was a screening mammo and USlike this. If it was done to someone under 40 or not high risk it would not be a screening exam. If it was a diagnostic exam that is completely different. It would be covered under the general policy with copay/maximums etc. Screenings and diagnostic mammograms/US are different and not covered under preventive medicine.
There are two sides, but you can alter that a bit if you get your asses to the primaries.
