Why A is correct
In Original Medicare, participating providers and suppliers submit claims directly to Medicare through CMS claim-processing contractors on the beneficiary's behalf. The beneficiary generally does not need to file paperwork for covered services; Medicare then pays its share and the MSN reflects the claim. Beneficiaries file claims themselves only in rare circumstances, such as for certain non-participating providers. This provider-submission model is the normal claims flow under the Medicare claims objectives.
Why the other options are wrong
- B) Beneficiaries do not generally pay first and seek reimbursement; providers who accept assignment bill Medicare directly.
- C) Original Medicare claims are submitted through Medicare's own claim-processing contractors, not through a private insurer's portal.
- D) Claims are required for payment, but the provider submits them; coverage does not trigger payment automatically without any claim.
Memory hook
The doctor's office does the paperwork in Original Medicare — the beneficiary's main job is to check the MSN.
