# Medicare IPPS Wage Index (geographic wage adjustment)

`medicare_silver.fact_ipps_wage_index` · Medicare Advantage, Part D, Medicaid · status live · 84,746 rows

The CMS IPPS Wage Index with Cap (FY2026), per hospital CCN — the geographic labor-cost adjustment factor used to localize the inpatient operating payment to a hospital's labor market. Bundled as a reference CSV and consumed directly by the RBP pricing engine (wage_index_for(ccn)); it is the wage-localization leg the dim_msdrg entry flags as "not loaded" for absolute IPPS dollars — this is where it lives.

**Grain.** One row per (fiscal_year, hospital CCN) -- IPPS wage index (with cap) for inpatient localization. DEEP FY2006-2026.
