Out-of-network care can be expensive. Always confirm provider participation before scheduling appointments to prevent surprise bills.
Understanding How Medicare and Doctor Networks Work
Medicare is supposed to make healthcare more affordable, but choosing the wrong doctor or hospital could leave you with a much higher bill than expected. Just because a provider accepts Medicare doesn’t mean they accept all Medicare plans. Knowing how doctor networks function under Medicare is crucial for keeping your out-of-pocket costs under control.
1. Verify If Your Doctor Accepts Medicare Assignment
Medicare has different categories of doctors based on their participation:
-
Participating Providers – These doctors accept Medicare’s approved amount as full payment, meaning you only owe your share of the cost, like deductibles or coinsurance.
-
Non-Participating Providers – These providers accept Medicare but may charge up to 15% more than the Medicare-approved amount (known as excess charges).
-
Opt-Out Providers – These doctors do not accept Medicare at all, meaning you will pay the full bill with no reimbursement from Medicare.
Before making an appointment, check your doctor’s Medicare status. You can call their office or look them up on Medicare’s provider directory.
2. Check If Your Medicare Plan Has a Provider Network
Depending on the type of Medicare coverage you have, doctor networks work differently:
-
Original Medicare (Part A and Part B) – You can see any doctor nationwide who accepts Medicare, but costs will vary if they don’t accept Medicare assignment.
-
Medicare Advantage (Part C) – Most plans require you to use a network of doctors. Going out-of-network may lead to higher costs or no coverage at all, depending on the plan type (HMO, PPO, etc.).
If you have a Medicare Advantage plan, review your provider directory regularly. Doctors can leave networks at any time, so don’t assume your coverage stays the same year to year.
3. Confirm Hospital and Specialist Coverage
Seeing a specialist or getting hospital care under Medicare isn’t as simple as just showing up. You need to verify if:
-
The specialist or hospital accepts Medicare and is in your plan’s network.
-
Your Medicare Advantage plan requires referrals or prior authorizations for specialist visits or procedures.
-
Emergency care is covered outside of your plan’s network (some plans only cover emergencies at certain facilities).
A quick phone call before your appointment could save you thousands of dollars in unexpected medical bills.
4. Understand How Out-of-Network Costs Work
If you go out of network, your costs will likely be much higher, or your plan may not cover them at all. Here’s what to consider:
-
Original Medicare – You’ll generally pay more if the provider doesn’t accept Medicare assignment.
-
Medicare Advantage – Some plans cover out-of-network providers but with higher copays, while others (like HMOs) may not cover them at all.
-
Balance Billing – If a provider is not contracted with Medicare or your Advantage plan, you might be responsible for the full bill.
To avoid these costs, always verify coverage before making appointments.
5. Watch for Changes During Open Enrollment
Medicare networks are not set in stone. Each year, insurance companies can change their provider networks. If you’re on a Medicare Advantage plan, you should:
-
Check your Annual Notice of Change (ANOC) to see if any of your doctors or hospitals are leaving the network.
-
Use Medicare’s Open Enrollment Period (October to December) to switch plans if your providers are no longer covered.
-
Consider whether a different plan might offer better access to the doctors and hospitals you prefer.
Being proactive during Open Enrollment can prevent you from losing access to your preferred providers and being stuck with unexpected expenses.
Making Sure You’re Covered Where It Matters Most
Understanding Medicare doctor networks isn’t just about avoiding surprise bills—it’s about making sure you get the care you need from the doctors you trust. Double-checking provider participation, network restrictions, and coverage details will help you stay ahead of any potential issues.
