## Session 2026-03-10 — Medicare Advantage, Senior Care & International Benchmarks
|
|
|
|
**Question:** How did Medicare Advantage become the dominant US healthcare payment structure, what are its actual economics (efficiency vs. gaming), and how does the US senior care system compare to international alternatives?
|
|
|
|
**Key finding:** MA's $84B/year overpayment is dual-mechanism (coding intensity $40B + favorable selection $44B) and self-reinforcing through competitive dynamics — plans that upcode more offer better benefits and grow faster, creating a race to the bottom in coding integrity. But beneficiary savings of 18-24% OOP ($140/month) create political lock-in that makes reform nearly impossible despite overwhelming fiscal evidence. The $1.2T overpayment projection (2025-2034) combined with Medicare trust fund exhaustion moving to 2040 creates a fiscal collision course that will force structural reform within the 2030s.

**Confidence shift:**
|
|
- Belief 2 (non-clinical determinants): **strengthened** — Commonwealth Fund Mirror Mirror 2024 shows US ranked 2nd in care process but LAST in outcomes, the strongest international validation that clinical quality ≠ population health
|
|
- Belief 3 (structural misalignment): **strengthened and deepened** — MA is value-based in form but misaligned in practice through coding gaming, favorable selection, and vertical integration self-dealing (UHC-Optum 17-61% premium)
|
|
- Belief 4 (atoms-to-bits): **complicated** — PACE's 50-year failure to scale (90K out of 67M eligible) despite being the most integrated model suggests structural barriers beyond technology

**Sources archived:** 18 across three tracks (8 Track 1, 5 Track 2, 5 Track 3)
|
|
**Extraction candidates:** 15-20 claims across MA economics, senior care infrastructure, and international benchmarks
