Law says insurers should pay for breast pumps, but which ones?

The Patient Protection and Affordable Care Act (PPACA) requires that health insurance plans need to provide new mothers with the equipment and services they need in order to encourage breast-feeding, which has been shown to protect a newborn’s health. To that end, breast pumps are a common piece of equipment needed, but the ACA doesn’t say exactly what kind of what brand of breast pump should be covered. Cheap pumps are clearly better for insurers’ short-term costs, but they also don’t work as well, especially for working mothers on the go.
