The Challenge

Problem

Horizon Health Plans, a regional Medicare Advantage insurer with 180,000 members, was struggling with declining Star Ratings and member satisfaction. Their digital experience was fragmented across multiple legacy systems, making it nearly impossible for members to manage their health benefits effectively.

Star Rating dropped from 4.0 to 3.5 over two years, putting $18M in quality bonus payments at risk

Member portal had 12% monthly active usage—far below the 35% industry benchmark

Average handle time for member services calls was 14 minutes, driving up operational costs

No mobile app—members relied on phone calls for even simple tasks like finding providers

Medication adherence programs had only 23% engagement, impacting quality measures

Annual wellness visit completion rate was 41%, well below CMS targets

Member complaints about difficulty understanding benefits increased 67% year-over-year

The combination of declining Star Ratings and poor member engagement was creating an existential threat. Horizon faced losing $18M annually in CMS quality bonuses while spending $4.2M on call center operations for issues that could be resolved digitally. Competitor plans with better digital experiences were winning during Annual Enrollment Period.

Our Approach

Strategy

We developed a comprehensive member engagement platform strategy centered on personalized health actions, proactive outreach, and simplified benefit navigation—all designed to improve both member experience and clinical quality measures simultaneously.

Member Journey Mapping

Conducted extensive research with 200+ Medicare members across demographics to understand their unique needs, technology comfort levels, and preferred communication channels. Created detailed personas for each member segment.

Quality-Driven Design

Aligned every feature with specific Star Rating measures—HEDIS quality metrics, CAHPS survey dimensions, and medication adherence programs. Every interaction was designed to move the needle on measurable outcomes.

Omnichannel Personalization

Built an intelligent engagement engine that delivers the right message, through the right channel, at the right time—coordinating outreach across app, web, email, SMS, and phone based on member preferences.

Accessibility-First Approach

Designed for Medicare population needs: large text options, high contrast modes, voice navigation, simplified language at 6th-grade reading level, and integration with screen readers and assistive technologies.

Care Gap Closure System

Created automated workflows to identify members with care gaps, deliver personalized outreach, facilitate scheduling, and track completion—turning passive data into proactive health interventions.

Provider Network Integration

Built real-time provider directory with availability, integrated scheduling, and transportation assistance to remove barriers between members and the care they need.
