Health care's widespread overbilling problem
The health care system's complex payment system gives doctors and hospitals lots of incentives to bill for more expensive services than they actually provide, a practice known as upcoding. Numerous settlements between health care companies and the Department of Justice indicate it's a widespread problem.
Why it matters: Upcoding affects everyone — it saps money from the taxpayer-funded Medicare and Medicaid programs and could lead to higher premiums for people with commercial insurance. But there's no evidence the health care system is fighting upcoding effectively, or that the problem will go away.
