I'm not sure but you can always call and ask. Babys r us has a link on their website that will put you in contact with companies in your area, who will verify with your insurance and send you one.
If you go to medela's website there's a link to where you can enter what insurance you have and what state you live in and it will give you a list of places that accept your insurance :)
Also tells you which medela pumps are covered.
