There are services which offer medical bill review for patients, usually via nurses or others with clinical and medical billing knowledge.

I know of these largely through news coverage, and cannot speak to how effective they are (or what the costs are).

The stories I've heard, though, of the absolute complete and total nightmare that is the US healthcare scam, are heartbreaking.

I'm looking for online references but cannot find any at the moment, maybe others here have more information.
