ARBITAL ATLAS

Know which providers belong in your LEAD ACO. 
Before you commit.

Arbital ATLAS (ACO TIN Level Analysis and Simulation) is built specifically for CMS's LEAD model.
Powered by national datasets and the actuarial depth your team needs.

THE SITUATION

LEAD decisions are happening right now, without the data to support them.

CMS's new LEAD Model is a 10-year commitment, and most ACOs are walking in with spreadsheets and educated guesses.

Hundreds of TINs to evaluate

ACOs are working through hundreds of physician practices, each with different cost profiles, risk scores, and attribution volumes, under a methodology most teams have never modeled before.

Slow, manual process

Most teams are doing this analysis by hand in scattered spreadsheets and building custom models from scratch. It can take weeks, introduces errors, and has to start over from zero every cycle.

August 5th Deadline

The deadline to add TINs to LEAD is August 5, 2026. After that, ACOs are locked in for the year. Getting the composition right from the start sets the tone for how your program performs.

THE SOLUTION

ATLAS: LEAD scenario modeling that runs at the speed of the decision.

Built for the complexity of LEAD, Arbital ATLAS gives ACOs a fast, clear view of how their TIN composition affects financial performance—powered by national VRDC data and deep actuarial expertise. 

Know which TINs improve your benchmark before you commit to them.
  Run every scenario in hours, not weeks. No manual spreadsheets.
Walk into the deadline with a clear, data-backed provider network strategy.

What Arbital delivers — from decision to documentation.

LEAD Education for Your Team

FOUNDATION

LEAD Education for Your Team

CMS' LEAD Model is the most ambitious ACO program ever launched. Our team of expert VBC actuaries will get you up to speed on it’s complexity and what makes this program fundamentally different from MSSP and ACO REACH.

Why ATLAS?

Built and maintained by expert VBC actuaries

The actuarial team behind ATLAS has spent careers inside value-based contracts. The platform reflects that depth, not just on launch day but as CMS methodology continues to evolve.

Fed by CMS national VRDC data

ATLAS runs on the same national claims data CMS uses to set benchmarks. Your scenario modeling reflects actual national cost and utilization patterns rather than approximations or proxies. ready for analysis.

Designed specifically for LEAD

ATLAS runs on proprietary actuarial logic built around how the LEAD model calculates benchmarks, risk, and shared savings.

THE BIGGER PICTURE

Build the right network, then optimize it

Combined with Arbital's full Actuarial AI platform, we support the full financial lifecycle of LEAD, MSSP, or any ACO risk program. From deciding which program is right for your organization and building the right provider network, to measuring performance and optimizing results before the contract cycle closes.

Where most teams are left reacting to results after the fact, Arbital's combination of actuarial expertise and AI-powered analytics gives teams the visibility to manage contract performance proactively, seeing cost drivers and performance gaps as they develop, with enough time to act on them.
