Important Information about Participating and Non-Participating Suppliers

If you get Medicare covered prescription drugs or supplies, make sure your pharmacy or supplier is enrolled in the Medicare Program. If you go to a pharmacy or supplier that is not enrolled, Medicare will not pay. You will be responsible for paying the entire bill for any drugs or supplies. You can find Medicare enrolled suppliers and pharmacies in this online directory.

For Medicare covered supplies, you should also find out if your pharmacy or supplier is participating with Medicare.

  • If they are participating, they must accept assignment. This means they must accept the Medicare-approved amount as payment in full. You should only pay your 20% co-pay (and any remaining Medicare Part B deductible) when you get your supplies. This online supplier directory will tell you if the pharmacy or supplier is participating with Medicare.
  • If they are not participating, they do not have to accept assignment. This means that charges may be higher, and you may pay more. You may also have to pay the entire charge at this time of service, and wait for Medicare to send you its share of the charge. This online directory will tell you if the pharmacy or supplier does not participate in Medicare.
