Months after U.S. senators requested financial documents in an investigation of how medical lab and insurance companies bill customers, LabCorp is the only company that hasn’t provided information to the Senate.
The inquiry is aimed at what’s termed as “pull-through” plans, which allegedly provide deep discounts on lab testing to insurance companies in exchange for their network doctors using a single, exclusive lab company for all their testing. The discounted rates are allegedly offset by billing Medicare and Medicaid at higher rates.
