# CMS PFS locality configuration (LOCCO), every RVU release CY2003-2026, stamped

`medicare_silver.fact_pfs_locality_config` · Medicare Advantage, Part D, Medicaid · status live · 2,381 rows

The LOCCO member of each CMS PFS RVU release ZIP (RVU03D..RVU26C) re-collected through the provenance envelope on 2026-09-07: state, state_name, carrier_number, locality_number, locality_name (fee schedule area) and the publisher's Counties text. It maps county groups to Medicare payment localities and MACs per year; it is NOT a county-FIPS crosswalk (LOCCO publishes text, not FIPS). Succeeds medicare_county_to_locality (one CY2025 RDS snapshot).

**Grain.** One row per source row of one RVU release's LOCCO file (calendar_year x MAC/carrier x locality x official Counties text) after exact duplicate source rows are dropped; natural key (release_label, row_seq).
