Bringing ACOs together to engage more Medicare beneficiaries in accountable care
The Coalition for Aligned Care (CAC) brings together ACOs, provider organizations, and policy leaders to advocate for Signed Voluntary Alignment (SVA) in the Medicare Shared Savings Program (MSSP).
Your voice matters in this critical planning process. By advocating to make voluntary alignment accessible through simple paper or electronic forms—as successfully demonstrated in ACO REACH—MSSP will be able to expand access to coordinated, high-quality care for millions of beneficiaries and generate meaningful cost-savings for our healthcare system.
The Opportunity
Millions of seniors still lack access to the coordinated, high-quality care that ACOs provide
-

PROBLEM
Voluntary alignment lets Medicare patients choose their main doctor, but fewer than 1 in 400 (0.25%) MSSP beneficiaries use this option today—leaving half of all FFS beneficiaries not connected to an ACO.
-

IMPACT
The ACO REACH Model offers a proven alternative—over 100,000 beneficiaries have chosen their doctor through simple paper or electronic forms, nearly 20× the MSSP rate.
-

SAVINGS
Adopting ACO REACH’s alignment process in MSSP could connect 560,000 more seniors to care and save Medicare $140 million annually.
The provisions in ACO REACH has created a streamlined, auditable, and scalable voluntary alignment process that can be replicated within MSSP and future ACO programs with minimal regulatory change.
The Policy Ask
We’re calling on CMS to:
Adopt Signed Voluntary Alignment (SVA) from ACO REACH into MSSP
Leverage the efficiencies and learnings the SVA process in ACO REACH by allowing paper and electronic attestation forms
Institutionalize flexibility and consistency across future ACO models

“Voluntary alignment empowers patients to choose the physician they trust most, rather than being passively assigned through claims. We’ve seen firsthand that when seniors have an active role in selecting their main doctor, engagement rises and outcomes improve. Bringing the ACO REACH alignment framework into MSSP would make this level of patient choice accessible to millions more beneficiaries.”
