On many doctor profiles you’ll see a short line: Medicare assignment: Accepts. If you’re on traditional Medicare, that line can mean a real difference in what you pay. If you’re not on Medicare, you can mostly ignore it. Here’s why.
The short version
A clinician who accepts assignment agrees to take the Medicare-approved amount as full payment for covered services. You pay your normal share — usually the Part B deductible and 20% coinsurance — and nothing more. The office bills Medicare directly, and Medicare pays them.
The three kinds of Medicare providers
Participating providers have signed an agreement to accept assignment for all Medicare services. Most doctors fall in this group.
Non-participating providers accept Medicare patients but can decide case by case whether to accept assignment. When they don’t, they can charge you more than the Medicare-approved amount — up to 15% more, a cap known as the “limiting charge” — and they may ask you to pay the full bill at the visit and wait for Medicare to reimburse you for its share. On ProVerdicts, these clinicians show “May accept for some services.”
Opt-out providers have left Medicare altogether. They can still see Medicare patients, but only under a private contract in which you agree to pay whatever they charge, and Medicare pays nothing. Opt-out clinicians are uncommon, and you’ll typically be asked to sign that contract before your visit.
What it means for you
- Traditional Medicare (Part A and B), with or without a Medigap plan: assignment matters. A clinician who accepts it costs you the least, and the paperwork is handled for you.
- Medicare Advantage (Part C): what matters more is whether the clinician is in your plan’s network. Assignment is about traditional Medicare billing; check your plan’s directory and call the office.
- Private insurance or Medicaid: assignment tells you nothing about whether a clinician takes your plan. Call the office and give them your plan name.
Where the information comes from
Medicare publishes the assignment status of every enrolled clinician in its Care Compare data, and that’s what we show on ProVerdicts profiles. Status can change, so if it matters for your budget, confirm it with the office when you book: “Do you accept Medicare assignment for this visit?” is a question every front desk is used to.
You can browse doctors in the Buffalo area and see each one’s Medicare assignment status on their profile.
