Final answer:
By authorizing a provider to accept assignment, the patient allows the provider to bill Medicare directly, accept the Medicare-approved amount as full payment, and only bill the patient for certain costs not covered by Medicare.
Step-by-step explanation:
When a patient authorizes a provider to accept assignment, the provider can submit claims to Medicare on behalf of the patient. This means that the provider agrees to accept the Medicare-approved amount for health care services as full payment. After the claim is processed, Medicare will pay the provider directly for the percentage of the cost that Medicare covers, and the provider can only bill the patient for the deductible, coinsurance, and any non-covered services. This consent simplifies the billing process for both the patient and the provider, allowing for a more streamlined financial interaction regarding medical services.
