If you have Original Medicare
You can see any provider who accepts Medicare, anywhere in the U.S., with no referral needed. There are three kinds:
- Participating (accepts assignment). The provider takes the Medicare-approved amount as full payment. You pay your deductible and 20% coinsurance.
- Non-participating. The provider accepts Medicare but not always assignment, and can charge up to 15% more than the approved amount (the limiting charge).
- Opted out. Medicare pays nothing; you pay the full bill under a private contract.
To search, use Care Compare on Medicare.gov: pick "Doctors and clinicians," enter your ZIP code and a specialty or name. You can also call 1-800-MEDICARE (1-800-633-4227).
If you have Medicare Advantage
- Search the plan's online provider directory, or call member services (the number is on your card).
- HMO plans usually need you to use network doctors and may require referrals; PPO plans let you go out of network at a higher cost.
- Call the office to confirm it is in your plan's network and accepting new patients. Directories aren't always current.
Oregon tips
- Check a license. The Oregon Medical Board's online license verification shows whether a physician or physician associate is licensed and any public board actions.
- Rural counties. In Grant, Harney, Lake, Umatilla and Union counties no Medicare Advantage plan is open to everyone for 2027, so finding doctors who accept Original Medicare matters most there. See your county and our rural Oregon guide.
- Tribal clinics. IHS and tribal clinics work differently from Medicare networks. See tribal health and Medicare.
- VA care. VA facilities are separate from Medicare. See veterans and Medicare.
If you're choosing a plan and want to keep your doctors, you can request a call from a licensed insurance agent who can check which plans from the companies they work with include them. You can also compare plans yourself at PlanMatch.

Frequently asked questions
How do I know if my doctor accepts Medicare?
Ask the office whether it accepts Medicare assignment. With Medicare Advantage, ask whether the doctor is in your specific plan's network, even if the plan's directory lists them.
What happens if my doctor opts out of Medicare?
An opt-out provider bills you under a private contract. Medicare pays nothing for those services, and you pay the full price.
Can I keep my doctor if I switch to Medicare Advantage?
Only if your doctor is in the plan's network, or the plan covers out-of-network care. Check before you switch, because networks differ by plan.
