Can we find overcharges on a hospital bill?

Yes, for the obvious stuff. Duplicate labs, a cancelled test that stayed on the bill, a panel split into parts, a visit coded higher than the note supports. Those are pattern problems, and that is what we check with you first.

It will miss context a nurse or a coder would catch. Treat the result as a work list. You still decide what to dispute. About the review explains the limit in plainer words.
