Geographic Indices IPPS Wage Index

The dataset has information on the Medicare payment adjustments of geographic indices for Inpatient Prospective Payment System (IPPS) wage index for the fiscal years 2010-2018. The Medicare System adjusts fee for service payment rates for hospitals and practitioners according to the geographic location in which providers practice, recognizing that certain costs beyond the providers’ control vary between metropolitan and nonmetropolitan areas and also differ by region.

Geographic adjustments are intended to ensure that the Medicare Program does not overpay hospitals and practitioners in certain areas and underpay in other as a result of geographic difference in price for resources such as clinical and administrative staff salaries and benefits, office or hospital space (rent), malpractice insurance (premiums), and other resources that are part of the cost of providing care. As a result, Medicare’s Inpatient Prospective Payment System (IPPS), other Institutional Prospective Payment System (other PPSs), and the Medicare Physician Fee Schedule (PFS, or fee schedule) all employ geographic adjustments factors (GAFs). The two geographic adjustments applied to Medicare payments for care provided by hospitals and practitioners are the hospital wage index (HWI) and three geographic practice cost indexes (GPCI). The index compares difference in price or quantity for a group of goods and services relative to an average value derived from a standard baseline geographic area or time period. The fundamental rationale for geographic adjustment is to create a payment structure that adjusts payments for the input price difference, such as employee compensation, that providers face when they provide care.

GPCIs helps to standardize the differences in resource costs incurred across geographic areas when those costs are compared with the national average costs for the physician work, practice expense and malpractice insurance components of the fee schedule. Specifically, the three adjustments are provided for the following: 1) Physician work reflects the time, skill, effort, judgment, and stress associated with providing one service relative to other services according to the HCPCS codes. On average, as of 2011, work accounted for 52.5 % of the geographic adjustment factor within the fee schedule. 2) Practice expense considers certain price for maintaining a clinical practice, including salaries and benefits for administrative and clinical employees, rent, equipment, and supplies. Practice expense associated with supplies and equipment are not adjusted geographically because they are purchased in a national market in which prices are similar across the country. On average as of 2011, the PE GPCI accounted for 43.7 % of the geographic adjustment. 3) Professional liability insurance PLI represents payment for professional liability malpractice expenses and on average, account for 3.9 % of the geographic adjustment.
