Independent medical review
An independent medical review (IMR) is the process where physicians review medical cases in order to provide claims determinations for health insurance payers, workers compensation insurance payers or disability insurance payers. Peer review also is used in order to define the review of sentinel events in a hospital environment for quality management purposes such as to look at bad outcomes and determine whether there was any mis-diagnosis, mistreatment or any systemic problems involved which led to the sentinel event.
