Need the pump too? Get it through insurance
Most health plans, including Marketplace plans, must cover a breast pump under federal rules (HealthCare.gov). We check your plan, get the prescription from your doctor, and ship a covered pump to your door. Replacement parts and milk storage bags can be covered too.
