Do all doctors accept Medicare Supplement (Medigap) plans?

Q: I have a Medicare Supplement Insurance plan and I was told by someone at my doctor’s office that they don’t accept that carrier’s plan. What’s going on?

A: Medicare supplement (Medigap) plans must be accepted by any provider who accepts Medicare. This is written into Social Security law. It is not uncommon for a front desk employee at a doctor’s office to get confused between Medicare Supplement plans and Medicare Advantage plans. You may want to check with their Billing Department since they are usually well-versed in these plans.
