Millions of Members Across Many Plans.

A large and multi-faceted organization.

One of the nation’s largest customer-owned health insurers wanted to improve Medicare Advantage star ratings and reap the benefits of expanded, personalized member engagement — which could impact everything from quality scores to risk adjustment to member loyalty.

Yet with nearly 20 million members in commercial, Medicaid, and Medicare Advantage plans across multiple states and growing demands for internal resources, the organization needed an external partner to scale health plan member outreach without sacrificing quality.

  • Coordinating engagement across large, complex plans
  • Scaling personalized outreach across millions of members
  • Managing multiple lines of business and programs simultaneously
  • Limited internal resources for expanded engagement

“As engagement coordination increases, so does the power to apply learnings for enterprise-level optimization.”
Carenet Health — Engagement Partnership Framework

SCALE.

20M Members

across Commercial, Medicaid & Medicare Advantage plans, managed through one strategically integrated engagement program — not separate vendors or platforms.

Now 13 programs. One coordinated strategy.

From a single pilot to a comprehensive partnership

The health plan had already established an initial relationship with Carenet Health, contracting for fitness program enrollment outreach. The two organizations immediately decided to partner on a new pilot — a Medicare HEDIS program to help members close gaps in care.

After just a few weeks of successful HEDIS outreach, the plan asked Carenet to take on its Medicare Advantage welcome calls. From there, the relationship quickly expanded, and as the partnership grew, so did synergies among the insurer’s plans and programs.

01
Technology Flexibility & Integration

Soon, Carenet teams were working within the plan’s care management and member services ecosystem — including the rewards-partner platform — leveraging flexible technology solutions that allow for seamless integration, real-time comprehensive data views, immediate updating, and the capacity to address a wider range of member needs with each interaction.

02

Confidence & Transparency

The trust that developed between the partners was significant and rooted in a dedication to transparency. A shared reporting dashboard was developed providing the insurer with ongoing confidence at the member, program, and management level. Performance-based contracts were created as a collective effort; if goals were met, it was a win-win for all.

03

Relentless Focus on Quality

Effective training and coaching programs — customized to the plan’s culture, population, technology, and programs — were a must-have for every new engagement initiative. Programs and interactions were continuously monitored for quality and effectiveness across phone, email, SMS, click-to-call, and AI-supported interactions.

04

Enterprise-Wide Programs = Enterprise-Wide Learning

  • Engagement siloes have been brought together to function as a well-coordinated machine
  • With each campaign, partners evaluate what worked and what could be improved, to apply learnings across the organization
  • Each iteration becomes smarter and more effective, thanks to compiled testing and data insights
  • Both partners achieve a big-picture line-of-sight into the complex member experience throughout the healthcare consumer journey
