Most Expensive Diseases.

The list of the 10 most expensive diseases comprises estimates calculated by Charles Roehrig, health economist at the Altarum Institute in Ann Arbor, Michigan, based on 2005 data. Previous government surveys included community-dwelling patients using data from the federal Medical Expenditure Panel Survey. Roehrig’s estimate, however, provides a fuller picture by also accounting for costs of treating patients in nursing homes, the military, prisons and mental hospitals.
