What to Do If a Supplier Does Not Accept Medicare Assignment
If a supplier does not accept assignment, your costs can be higher and the paperwork different. Here is how to check, compare and decide.
What does it mean when a supplier does not accept assignment?
A supplier that accepts assignment agrees to take the Medicare-approved amount as full payment for covered items, and you pay only your share such as the deductible and coinsurance. A supplier that does not accept assignment can set its own price, and Medicare rules about what you may be charged are different. Always ask what you will pay before you agree to anything.
Should you walk away?
Not automatically, but compare. Ask for the total price in writing, including delivery and setup, then ask at least one supplier that accepts assignment for the same item. Use the shortlist tool and the "Accepts Medicare assignment" filter on any city page to find alternatives quickly.
How do you find a supplier that accepts assignment?
Open your state or city page, tick Accepts Medicare assignment, and sort by equipment range. Call each supplier and confirm that they accept assignment for your specific item, because the listing is a general indicator and can change. The assignment guide explains the terms.
What should you ask before agreeing?
Ask: what is the full price, what will Medicare pay, what will I pay, and will I be asked to pay up front? Get the answers in writing. Use the printable question checklist.
What if you already ordered?
Keep your paperwork and call the supplier and 1-800-MEDICARE (or your plan) to ask how the claim will be handled and what you may owe. Do not ignore bills; ask for an itemized statement.

Frequently asked questions
Is a supplier that does not accept assignment legitimate?
It can be. Accepting assignment is a payment agreement, not a quality rating. Check that the supplier is enrolled in Medicare and compare the total cost with other suppliers.
Do all suppliers in a city accept assignment?
No. City pages show the share that accept it, and you can filter the list to show only those that do.
Can assignment status change?
Yes. Always confirm by phone for your specific item before you order.
