Two-Sided Risk: Symmetric Upside and Downside Contracting
A two-sided risk contract has both upside (shared savings or gain) and downside (shared losses or repayment). Distinct from upside-only arrangements where the provider can benefit but cannot lose.
The MSSP risk-track ladder
- Level A (BASIC) — upside-only, glide-path entry track for ACOs new to value-based care.
- Level B — upside-only, second year of glide path.
- Level C — first two-sided level (low risk).
- Level D — two-sided, higher risk and higher reward.
- Level E (ENHANCED) — highest risk, highest reward; closest to REACH-style arrangements.
ACOs entering MSSP after July 2019 progress through the BASIC glide path then must move to two-sided risk within 5-7 years.
Why two-sided risk changes operations
Under upside-only, an ACO that doesn't improve simply doesn't earn savings — neutral outcome. Under two-sided risk, the same ACO loses money. The discipline shift is real: continuous monitoring becomes mandatory, the population health team gets resourced differently, the CFO models risk-corridor exposure into the budget, and care management investments that “might pay off” under upside-only become “must pay off” under two-sided.
Where Vizier fits
Vizier supports both sides of the calculation: spend trajectory monitoring (the financial side) and quality measure performance (the multiplier side). The combined view tells the ACO leadership whether they're tracking toward shared savings, neutral, or shared losses — with enough lead time to act.
