Summary: Nursing home patients are an attractive target for fraudulent and abusive health care providers that bill Medicare for undelivered or unnecessary services. A wide variety of providers, ranging from durable medical equipment suppliers to laboratories to optometrists and doctors, have been involved in fraudulent and abusive Medicare billing schemes. Several features make nursing home patients attractive targets. First, because a nursing facility houses many Medicare beneficiaries under one roof, unscrupulous billers of services can operate their schemes in volume. Second, nursing homes sometimes make patient records available to outsiders, contrary to federal regulations. Third, providers are permitted to bill Medicare directly, without certification from the nursing home or the attending physician that the items are necessary or have been provided as claimed. In addition, Medicare's automated systems do not collect data to flag improbably high charges or levels of services. Finally, even when Medicare spots abusive billings and seeks recovery of unwarranted payments, it often collects little money from wrongdoers, which either go out of business or deplete their resources so that they cannot repay the funds.
