Absolutely. Generally speaking, insurance companies should promote and encourage healthy behaviors. If it could save them money in the long run, it's a worthwhile investment. And before anyone starts with that 'pay for it yourself' bs, we PAY for our insurance so that certain things can be covered. And as much as some of us pay, we've definitely covered the cost of a damn breastpump.

My insurance pays for my breast pump

My insurance now pays for it. (Tri-Care)

According to healthcare.gov: Health insurance plans must provide breastfeeding support, counseling, and equipment for the duration of breastfeeding. These services may be provided before and after birth. This applies to Marketplace plans and all other health insurance plans, except for grandfathered plans.

My insurance pays for breast pumps now, but they didn't when my son's were born. It's nice not to have to pay a couple hundred bucks for a pump, my twins wouldn't have been able to get breast milk at all if I hadn't had one last time.
