What it is

1The CMS Hospital Service Area file — for each hospital (CCN) the ZIP codes its Medicare FFS patients reside in, with total_cases, total_days_of_care, total_charges.
2The referral-GEOGRAPHY layer: which markets a hospital draws from, and (inverted) which hospitals serve a ZIP / compete in a market.
3Multi-year (2015–2024), partitioned by data_year.
