HCC Coding Services

Increasing RAF Accuracy by 18% for HCC Coding Review

Case Study

A Medicare Advantage provider with over 25,000 members was facing lower-than-expected RAF scores despite managing a high-risk patient population. An internal review revealed missed chronic conditions, documentation gaps, and inconsistent coding practices.

18%RAF Accuracy Improvement
14%Increase in HCC Capture
35%Fewer Coding Discrepancies

Approximately 22% of reviewed charts contained undocumented or underreported chronic conditions, creating reimbursement risk and reducing the accuracy of member risk profiles.

By implementing targeted HCC coding services, conducting a comprehensive retrospective HCC review, and strengthening documentation practices, the organization improved RAF accuracy by 18% within 12 months.

Client Overview

Industry: Medicare Advantage

Members: 25,000+

Focus: Risk Adjustment & HCC Coding

Objective: Improve diagnosis capture and RAF score accuracy

Challenges

Chronic Conditions Missing from Annual HCC Recapture

Many chronic conditions, including diabetes with complications, CKD, COPD, and CHF, were not consistently documented and reported each year, leading to missed HCC opportunities and lower RAF scores.

Insufficient Documentation Supporting HCC Submission

Approximately 22% of charts lacked documentation that met CMS MEAT requirements, preventing valid HCC submission even when conditions were clinically present.

Coding Variability Across Providers

Differences in provider documentation practices resulted in inconsistent diagnosis capture and coding discrepancies across the network.

Revenue Leakage from Missed Risk Conditions

Underreported chronic conditions caused RAF scores to underrepresent member complexity, impacting reimbursement accuracy.

Limited HCC Audit Oversight

The organization lacked a structured HCC coding audit process to identify recurring coding and documentation issues.

Our Approach

To improve risk adjustment performance, we implemented a focused strategy that included:

  • Retrospective HCC chart reviews

  • Certified HCC coders

  • MEAT documentation validation

  • Provider education sessions

  • Monthly HCC coding audits

The goal was to identify missed diagnoses, improve documentation quality, and strengthen coding consistency across providers.

Problems & Solutions

Results

18% Improvement in RAF Accuracy

More accurate diagnosis capture improved the reliability of RAF scores across the member population.

14% Increase in HCC Capture Rates

Retrospective reviews identified previously missed chronic conditions, increasing overall HCC capture.

35% Reduction in Coding Discrepancies

Standardized workflows and education significantly reduced coding inconsistencies.

Improved CMS Audit Readiness

Better documentation practices and ongoing audits strengthened compliance and audit preparedness.

Results Summary

  • 18% improvement in RAF accuracy

  • 14% increase in HCC capture rates

  • 35% reduction in coding discrepancies

  • Improved CMS audit readiness

  • Reduced revenue leakage

  • Stronger provider documentation compliance

Conclusion

The provider was facing challenges with missed chronic condition reporting, documentation gaps, and inconsistent coding practices. Through specialized risk adjustment coding services, a structured retrospective HCC review, and ongoing HCC coding audits, the organization significantly improved diagnosis capture and RAF score performance.

This case study demonstrates how proactive HCC coding services can support accurate risk adjustment reporting, improve compliance, and drive measurable financial results.
