This 2011 report represents Milliman's triennial summary of estimated U.S. average costs per member per month (PMPM), billed charges, and utilization related to the 30 days prior and 180 days after admission for treatment for organ and tissue transplants. For charges pre- and post-transplant admission, we include all medical costs associated with the transplant patient.
