Case Study—

Reducing Friction in High-Volume Claims Adjudication


As Senior UX/UI Designer and UX Lead on the claims platform at UnitedHealthcare, I led UX efforts to improve manual adjudication workflows for Medicare Supplement claims supporting AARP members. This work focused on reducing scroll fatigue, improving data comparability, and lowering cognitive load for claims examiners working outside auto-adjudication. The goal was not to change system logic, but to make critical claim review tasks faster, clearer, and lower risk through UI-level improvements.

The Challenge

Although auto adjudication processes ~98% of claims, the remaining 1–2% are routed to examiners for manual review. These complex cases are extremely high-value, and slowdowns have a direct financial and operational impact.

One of the highest-friction areas was the Duplicate Check workflow, in which examiners compare a check received from a third-party system against potential matches in the claims system.

The Problem

The new claims system replaced a legacy claims system but introduced usability issues that slowed examiners and increased frustration.

Key challenges included:

  • Misaligned data structures:
    The third-party system displayed checks horizontally.
    We displayed them vertically.

  • Excessive scrolling and fragmented layouts

  • Inconsistent data presentation across systems

  • Inefficient use of space

  • High cognitive effort when comparing duplicate claims

  • Productivity loss in high-volume workflows

“There are many barriers that slow us down—especially errors and slowness between screens.”
— Claims Examiner

Strategy

We launched a focused UX research initiative to understand examiner pain points and identify UI changes that could deliver immediate efficiency gains without backend changes.

The approach emphasized:

  • Observing real examiner workflows

  • Identifying repeat friction points

  • Prioritizing improvements aligned with business constraints

Research Approach (Condensed)

  • Screener survey to surface key issues

  • 1:1 interviews with claims examiners and trainers

  • Thematic and sentiment analysis

  • Findings mapped directly to design opportunities

  • Key UX Improvements

The biggest blocker wasn’t just “too much scrolling.” It was a mismatch between the mental model examiners used and the UI they were given.

  • Vertical data grouping by aligning with mental models for easier comparison

  • Reoriented data layouts to reduce scrolling

  • Reduced clutter by optimizing whitespace

  • Improved visual hierarchy for faster comparison

  • Reduced cognitive translation between systems

Impact

  • Improved review efficiency through reduced scroll fatigue

  • Lower cognitive load for high-volume examiners

  • Increased confidence during manual adjudication

  • Positive post-launch feedback validating UI-only improvements

Deep Dive: UX Research

Personas

Following interviews, contextual observation, and survey analysis, I synthesized findings into personas representing claims adjusters and processors, informing a duplicate check redesign grounded in real-world workflows.

Key Visual & Usability Themes Reported by Claims Processors for the New Update

Themes represent recurring feedback patterns across examiner responses, illustrating which aspects of the redesigned Dupe Check screen are providing the most value.

Legacy Claim System Slowly Phased Out (Before)

Claim examiners had long relied on UPCS. a third-party claims services tool that presented duplicate checks in a horizontal, terminal-style format, establishing a familiar mental model for comparison.

As UPCS began to be phased out, an early internal replacement introduced a vertically oriented table to align with existing UI patterns, but this created unnecessary cognitive friction given the volume and importance of duplicate checks.

Our team redesigned the experience to restore a horizontal, side-by-side layout, preserving the established mental model and enabling faster, more confident duplicate-claim evaluation with minimal cognitive disruption.

Results and Impact: Efficiency Gains


Examiners could now:

  • Compare data faster

  • Maintain context without losing their place

  • Reduce total clicks and scroll behaviors

Accuracy Improvements

By aligning FOX with the third-party system:

  • Misreads dropped

  • False matches reduced

  • Decisions were made with greater confidence

User Satisfaction

Examiners described the new layout as:

“More intuitive.”

“Finally matches how we work.”

“Night and day compared to before.”

Organizational Value

  • Supported a high-revenue AARP Med Supp line of business

  • Strengthened trust in UX

  • Demonstrated value during a cycle when UX requests were at risk of reprioritization

  • Helped create a pattern library for future FOX enhancements
