Replication Package: Prospective Payment Compresses Charges More Than CCR-Estimated Costs

Replication package for "What Does Medicare Prospective Payment Compress? Charges, CCR-Estimated Costs, and Margin Risk Across Common Conditions." Contains cleaned data extracts (official CMS Medicare Inpatient Hospitals by Provider and Service files, calendar year 2013 and fiscal year 2023, for sepsis, heart failure, and pneumonia DRGs), Python analysis scripts (compression ratios, cost-to-charge ratio merges, gap regressions, bootstrap confidence intervals), and a README documenting data sources, sample construction, and a one-command reproduction path. All source data are official, public CMS downloads.
