Dateline investigation of "paper reviews" used to deny claims

Check out this NBC Dateline series (there are 4 parts), which describes how State Farm and other insurance companies use a "paper review" process to deny claims. Non-doctors write reports that are signed by doctors, oftentimes without review of records by the actual doctor. Doctors sign 30-50 reports in "autograph sessions" without reviewing records, and the reports were often changed after being signed by doctors. The reports were written in a way slanted in favor of the insurance companies to downplay injuries, limit claim payments, and cut care.
