Medicare is the federal health insurance program for people 65 and older and some younger people with disabilities. Most US doctors accept Original Medicare (Parts A and B), and Medicare Advantage plans (Part C) have their own networks.
A doctor who "accepts assignment" agrees to Medicare's approved amount as full payment. Medicare Advantage plans (offered by private insurers like UHC, Humana, Aetna, BCBS) have separate provider networks — even if a doctor takes Original Medicare, they may not be in your Medicare Advantage plan.
They agree to charge no more than the Medicare-approved amount and to bill Medicare directly.
No. Medicare Advantage plans have their own networks. Confirm with both your plan and the office.
