Breast pump through BCBSIL?

Any ladies with Blue Cross have details about getting a breast pump through insurance? I asked a rep early on in my pregnancy but she was so vague on what was available. It sounded like she wanted me to order through one of their partners but I'd much rather pick one out at the hospital. The doctor said she would write a prescription, I don't know if that makes a difference. 🤷‍♀️
