What is an EOB & how does it work?

Your EOB has a lot of useful information that may help you track your healthcare expenditures and serve as a reminder of the medical services you received during the past several years. A typical EOB has the following information, although the way it's displayed may vary from one insurance plan to another:

What's the difference between a healthcare provider's Bill and EOB?

Typically, the amount your healthcare provider charges for her services, as seen on her bill and on the EOB, and the amount your payer reimburses for that service, as seen on the EOB only, are two different things. The reimbursement is usually less than the healthcare provider's charge. You can use the EOB to compare those two amounts.

Do I need a customer service phone number for my EOB?

Your EOB should have a customer service phone number. Do not hesitate to call that number if you have any questions or concerns about the information on the EOB. Your EOB is a window into your medical billing history.
