Health insurer Aetna and physician staffing firm Mednax are at each other's throats in federal court. Each side is accusing the other of using fraudulent or nefarious practices to boost profits — at the expense of sick infants.

The big picture: Taxpayers and people with job-based health insurance ultimately pick up the tab for these kinds of billing feuds, and it's not clear anyone will benefit after the dust clears.
