Connecticut's largest physician organization wants answers after several doctors received faxed requests for patients' medical information from an insurer. UnitedHealthcare subsidiary Ingenix sent faxed requests to physicians, asking for information dating to Jan. 1, 2008. Medical society Executive Vice President Matthew Katz says while it is not uncommon for insurers to ask to review patients' charts, doctors don't generally receive requests for information by fax and they don't fax such sensitive information to third parties they don't know.
