The challenge
Getting the data you need to make ACO value a reality
Innovative payment models hold great promise to improve outcomes and quality while managing costs. Achieving these goals requires in-depth performance insights—something you cannot get from standard Medicare ACO reports.
The solution
Succeed in value-based care with industry-leading insights
Milliman MedInsight ACO Builder quantifies participant-level performance inside and outside your ACO, based on comprehensive data that is always current. Through Excel or a web-based solution, it helps you improve partnerships with providers and payers to make healthcare more affordable, build the best network for your patient population, and excel in value-based care.
ACO Builder is more than just a dashboard. It is a full pro-forma projection model with Milliman’s unparalleled ACO expertise, and the complete Medicare experience data is built in. You can also connect with the same consultants who created ACO Builder to tailor it to your needs and interpret results for your organization.
ACO Builder is available for all major Medicare risk programs including:
- Medicare Shared Savings Program (MSSP)
- Direct Contracting (DC)
- Accountable Care Organization Realizing Equity, Access, and Community Health (ACO REACH)
- Medicare Advantage
