Health care bills have mistakes, sometimes lots of them.
The figure most often quoted is that up to 80% of medical bills have errors. I’ve looked for the original source of that statement without success, but I did find one medical bill review company, Medical Billing Advocates of America, who noted that in their practice 3 out of every 4 bills they review have errors. (Caveat: Theoretically only people who think they have a billing issue would be submitting their bills for review, so this may create a falsely high rate.)
Still, you probably look over your restaurant bill and ask the waiter about charges you see that don’t look right before you pay it, right? The same applies for medical bills – and even though you may not fully understand everything that was ordered for you, asking about what’s on the bill you don’t recognize before you pay it is just smart.
