More than 80 percent of payments to chiropractors should not have been made, investigators found. This isn't the first time the Centers for Medicare and Medicaid Services has been warned repeatedly that chiropractors are billing for services that don't comply with Medicare requirements.

Medicare is only supposed to cover manual manipulation of the spine in some cases of subluxation - where spinal bones are misaligned. But in studying records on a sample of 43 services, subluxation wasn't present in 37, the OIG found. For the remaining six, subluxation was present but medical records didn't indicate it was treated by manual manipulation.
