Like most things involving the government, it's kind of complicated, but basically:
A participating provider has agreed to submit all claims to the Medicare program. A non-participating provider may choose to submit, or not to submit, claims to Medicare on a case-by-case basis.
The biggest practical difference to a patient covered by Medicare is that if they go to a participating provider they will probably only be asked to cover the Medicare co-payment at the time of service. If they go to a non-participating provider, they may be asked to make payment in full at the time of service.
No. This is false. - A Medicare participating provider can not decide to accept assignment on a claim-by-claim basis. The provider registers with Medicare as a provider that will accept assignment and must accept assignment on all patients.
Yes
accepting
Yes. Original Medicare does not require you to obtain a referral before seeing a provider, but it does expect you to see a Medicare provider.
Nonparticipating provider
"Medicare Allowable" charges: Providers who participate with Medicare agree to accept the Medicare allowable charge as full payment. Bear in mind that because Medicare is an 80/20 plan, the patient is still responsible for the 20 percent of the allowable charges not paid by Medicare. * For example: You have chemotherapy in your physician's office and Medicare is billed $500.00 for the service. The Medicare allowable or assignment for your chemotherapy treatment is $300.00. Your physician is paid 80 percent of $300.00 or $240.00. You are responsible for only the $60.00 not paid by Medicare but considered allowable under Medicare UCR fee schedule. This is because participating Medicare providers may not bill the patient for the balance amounts above the Medicare allowable fee schedule (known as "balance billing"). It is important to verify that your provider "Accepts Medicare Assignment" or is a "Medicare Provider" to avoid unexpected and potentially large out-of-pocket expenses.
It means that the provider agrees to bill Medicare for treatment and accept Medicare as payment in full (except for co-pays and deductibles).
