Medicare Summary Notice (MSN)

A Medicare Summary Notice (MSN) is sent to Medicare beneficiaries for each claim that is processed. On nonassigned claims, the MSNs are issued as the claims are processed. On assigned claims, the MSN is mailed in 90-day cycles. Even though the supplier may have received notification of payment, the beneficiary may not have received his/her MSN.

The MSN explains what claim is involved, the types of service(s), the supplier and other identifying information that explain the payment and/or denial. Suppliers should remind clients to review each MSN carefully and report any suspected errors as soon as possible.
