Mercy, one of the largest health systems in Missouri, is threatening to stop accepting Anthem insurance unless an agreement on how much the insurer reimburses hospitals for care is reached by the end of the year. Chesterfield-based Mercy, which operates dozens of hospitals and hundreds of other outpatient locations in the region, has announced it intends to move out of the insurer's network in January if Anthem does not agree to a new contract. The contract sets the amount of money the insurer pays hospitals for surgeries, checkups and the thousands of other services the health system provides.
