Measuring geographic variations in hospitals' capital costs

The Health Care Financing Administration (HCFA) has proposed incorporating hospital capital payments into the Medicare prospective payment system. HCFA's proposal includes an adjustment to capital payments for geographic differences in capital costs, derived from the prospective payment system area hospital wage index. Alternatively, the geographic adjustment could be based on an area construction cost index. Geographic construction cost indexes calculated from the cost per square foot of finished structures or from construction labor and materials input prices are evaluated in this article.
