What They AreAn MSN is a lot like Explanation of Benefits notices received from private health insurance plans. It is a list of all claims sent to Medicare in the past three months for that beneficiary. It shows what claims have been made, what Medicare has paid out and what the beneficiary is responsible for paying.
The MSN is not a bill. If there are any outstanding charges listed on the MSN, the beneficiary's health care provider will have to bill the beneficiary directly. No payments need to be sent to Medicare after receiving an MSN.
Who They Come FromThe MSN may come from Medicare directly, or it may come from a private insurance company that has been contracted by Medicare to process claims. If this is the case, then the name and address of a private insurance company may be present on the MSN.
If an item is denied and the beneficiary wants to appeal, he or she must appeal to the carrier listed on the MSN.
