Insurance companies are usually very specific about what they will and won’t cover. They get down to the procedure and diagnostic codes and set conditions on when they will cover, how much they’ll cover, and when that changes. Coverage is a general term that indicates the insurance company paying any portion of the service, though it could be 5%, 25%, 80%, or 100%. Any amount of participation in paying the expense is called coverage. Understanding what kind of coverage – what % coverage and for what period is essential.
