Medicare Part B excess charges are an up to 15% additional fee on top of the Medicare-assigned cost for a healthcare service. Thus, if your physician does not accept Medicare assignment, they may charge you up to 15% more, and you are responsible for covering this cost in full. Some Medicare Supplement plans in Louisiana (Medigap Plan F, Plan G, and their high-deductible versions) cover excess charges, so you do not need to worry about them with one of those policies. However, with a Medicare Supplement Plan N policy, you will need to be aware of these charges as Plan N does not cover them. Not all states allow physicians to bill for excess charges. However, Louisiana does not have any laws in place to ban excess charges. Thus, if your physician does not accept Medicare assignment, you could be responsible for these expenses unless your Medicare Supplement plan covers them. It’s worth mentioning that such costs are rare. For the most part, Medicare Part B excess charges are not a part of normal billing processes even when receiving healthcare services in states that allow them. However, you should always check into the costs of your healthcare providers before enrolling in Louisiana Medicare Supplement plans.
