Donor breast milk is available through non-profit milk banks, which are the safest and most common source for families in the United States and Canada. Most families order directly from accredited milk banks, either through a hospital or for home delivery. The cost typically runs $3 to $5 per ounce, and depending on your state, insurance may cover part or all of it.
Non-Profit Milk Banks
The Human Milk Banking Association of North America (HMBANA) is the main network of accredited, non-profit milk banks across the U.S. and Canada. These banks collect milk from screened donors, pasteurize it, test it for bacterial contamination, and distribute it to hospitals and families. HMBANA’s website has a searchable directory so you can find the milk bank closest to you.
Some of the larger banks include the Mothers’ Milk Bank Northeast, the Mothers’ Milk Bank in Colorado, and the Northwest Mothers Milk Bank. Each operates independently but follows the same HMBANA guidelines for donor screening and milk processing. If you don’t live near a milk bank, most will ship frozen milk directly to your home.
How to Order for Home Use
If your baby is at home rather than in a hospital, you can still order donor milk. At many HMBANA-affiliated banks, outpatient families can order up to ten 100-milliliter bottles (about 3.4 ounces each) without a prescription. After that initial order, you’ll need a prescription from your baby’s doctor to continue purchasing.
The process is straightforward: contact the milk bank, place your order, and receive frozen milk shipped to your door. Milk banks prioritize their supply for hospitalized premature and critically ill infants first, so availability for outpatient families can vary. If one bank has a waitlist, try another in the HMBANA network.
What Donor Milk Costs
Non-profit milk banks charge a processing fee of $3 to $5 per ounce. That’s not profit; it covers donor screening, pasteurization, lab testing, and shipping. For a baby eating 20 ounces a day, that works out to roughly $60 to $100 per day, which adds up fast. Shipping costs are additional and depend on the bank and your location, since frozen milk needs to travel quickly to stay safe.
Some milk banks offer financial assistance programs or sliding-scale fees for families who can’t afford the full cost. It’s worth asking directly when you place your order.
Insurance Coverage by State
Insurance coverage for donor milk is inconsistent, but it’s expanding. Several states now require Medicaid or commercial insurers to cover donor milk under specific conditions. Coverage almost always requires a medical need, not just parental preference.
States with some form of Medicaid coverage include California, Illinois, Kansas, Kentucky, Louisiana, Missouri, New Jersey, New York, Oregon, and the District of Columbia. The qualifying criteria vary. California covers donor milk when the mother is unable to breastfeed and the infant can’t tolerate formula. Illinois has a broader list that includes babies born under about 3.3 pounds, infants at high risk for a serious intestinal condition called necrotizing enterocolitis, and those with congenital heart disease or sepsis. New York and New Jersey cover both Medicaid and commercial insurance plans, with similar medical criteria.
If your baby was premature, has a gastrointestinal condition, or has a congenital heart defect, ask your pediatrician whether donor milk qualifies for coverage in your state. Even in states without formal mandates, some insurers will approve it on a case-by-case basis with a letter of medical necessity.
How Milk Banks Screen for Safety
HMBANA milk banks use a multi-step screening process. Donors first complete a detailed health and lifestyle questionnaire covering medications, international travel, and recent illnesses in their household. Their blood is then tested for HIV, HTLV (a virus related to HIV), syphilis, and hepatitis B and C. Each donor also needs a medical release from their own healthcare provider confirming they’re healthy enough to donate.
Once the milk arrives at the bank, it goes through Holder pasteurization: heating to 62.5°C (about 145°F) for 30 minutes. This is the standard method recommended by every international milk banking guideline. It eliminates bacteria and viruses while preserving most of the milk’s immune and nutritional properties. After pasteurization, samples are cultured again to confirm no bacterial growth before the milk is cleared for distribution.
For-Profit Companies
A smaller number of for-profit companies also sell donor human milk products. Prolacta Bioscience is the most well-known, primarily supplying concentrated human milk products to hospital NICUs rather than selling directly to families. These products are heavily processed into specialized nutritional formulations for extremely premature infants, so they’re not the same as ordering bottles of pasteurized milk from a non-profit bank.
For-profit companies pay their donors, which non-profit banks do not. This distinction has sparked debate. Critics argue that paying for milk can divert supply away from non-profit banks, while supporters say it motivates more women to donate and funds more rigorous processing. For most families looking to buy donor milk for home use, non-profit HMBANA banks remain the most accessible and transparent option.
Why Peer-to-Peer Milk Sharing Carries Risk
Online platforms exist where individual mothers sell or share breast milk directly. The price is lower, often $0.50 to $2 per ounce, but there’s no institutional screening, no pasteurization, and no bacterial testing. Studies have found that milk purchased online frequently contains harmful bacteria, and there’s no way to verify whether a seller is taking medications, using drugs, or has an undiagnosed infection.
The gap in safety is significant. Milk bank donors are blood-tested, medically cleared, and their milk is heat-treated and lab-tested before it reaches your baby. Peer-to-peer milk skips every one of those steps. If cost is a barrier to using an accredited milk bank, contact the bank directly about financial assistance before turning to unregulated sources.
How Shipping Works
Milk banks ship frozen donor milk packed in insulated coolers. The milk needs to arrive still frozen, so most banks use overnight shipping. Expect your milk to arrive in a styrofoam or insulated container, sometimes packed with dry ice. Once it arrives, transfer it to your freezer immediately. If any bottles have fully thawed during transit, contact the milk bank for guidance before using them.
Shipping costs vary by distance and carrier but typically range from $20 to $50 on top of the milk’s processing fee. Some banks absorb shipping costs for families with financial need or for orders above a certain size.
