Answer & full 3-part explanation (select an option above, or peek)
Why A is correct
The Medicare Summary Notice (MSN) is the quarterly statement CMS sends after claims are processed. It itemizes each service, the provider, the Medicare-approved amount, the amount Medicare paid, and the beneficiary's remaining responsibility. It is an informational summary, not an upfront bill — under assignment, Medicare pays its share directly to the provider. The MSN is an official CMS document and does not market plans or compel any purchase. The MSN is issued automatically after each quarter's claims are processed.
Why the other options are wrong
- B) Medicare pays its share directly to assigned providers; the MSN is a summary of that process, not a bill the beneficiary must pay first. The MSN simply reports what was paid and what remains.
- C) The MSN is an official Medicare (CMS) document, not private-insurer marketing material. It is an official CMS document, and it is certainly not private-insurer marketing material of any kind whatsoever.
- D) The MSN only reports claims activity; it imposes no requirement to buy a Medigap policy. The MSN itself imposes no purchase obligation of any kind on the beneficiary whatsoever.
Memory hook
MSN = Medicare's quarterly report card on your claims: what was billed, what was approved, what was paid, what's left for you.
