Wage Index Review
20.4 – Wage Index Review
(Rev. 27, 12-19-03)
Section 1886 (d)(s)(E) of the Social Security Act, “Adjusting for Different Area Wage
Levels,” requires the Secretary to adjust the proportion of hospital costs attributable to
wages and wage-related costs for area differences in hospital wage levels. This
adjustment factor, the wage index, reflects the relative hospital wage level in the
geographic area of the hospital compared to the national average hospital wage level.
Wage Index reviews must be completed on all cost reports for short-term acute inpatient
prospective payment system (IPPS) hospitals and hospitals that would otherwise be
subject to IPPS if they did not have a waiver. Use the latest wage index desk review
program released by CMS prior to the due date of the yearly wage index reviews.
Wage index periods follow the federal fiscal period of October 1 – September 30. If a
hospital has more than one cost report beginning during the wage index period (for
example, a hospital has two short period cost reports beginning on or after October 1,
through September 30 of a given year), conduct a desk review on only one of the
reporting periods. Select the longest period. If there is more than one period of that
length, select the latest period.
