| Issue | What becomes possible |
|---|---|
| #9 Low-Value Care | Identify unnecessary inpatient procedures by volume, geography, and hospital across 3 states. |
| #16 Upcoding | DRG severity distributions at hospital level, multi-state. Flag outlier coding patterns. |

| Issue | What becomes possible |
|---|---|
| #3 Hospital Pricing | "Your hospital charges UnitedHealthcare $47K for a hip replacement. Across town: $29K." Real prices people can look up. |
| #10 Consolidation | Pre- and post-merger negotiated rates at acquired hospitals, procedure by procedure. |
| #14 Facility Fees | Same CPT code at hospital outpatient vs. ambulatory surgery center. Real prices, not estimates. |

This is the dataset that produces JAMA-publishable, congressionally-citable findings. It lets us follow individual patients across time, link denials to outcomes, trace spending through vertically integrated systems, and answer questions no other dataset can.
| Issue | What becomes possible |
|---|---|
| #8 Denials | Follow every denied MA patient. ER visits, readmissions, mortality. The actual human cost of wrongful denials. |
| #9 Low-Value Care | Every unnecessary procedure for 65M patients, linked to outcomes. The definitive national overuse estimate. |
| #10 Consolidation | Patient-level cost changes before/after mergers. Evidence an FTC proceeding could cite. |
| #16 Upcoding | Full DRG distribution for every Medicare hospital. Flag implausible coding with statistical precision. |
| #22 FFS Trap | Same demographics in FFS vs. MA. The definitive fee-for-service volume premium. |
| #31 Capstone | Trace patient flows through vertically integrated systems. Are UNH patients funneled to Optum at higher cost? |
