Supporting health plan priorities

Manifest MedEx enables California’s leading health plans to better coordinate care, improve patient outcomes, manage population health, and improve efficiency.

MX’s solution suite, which includes MX Notify, MX Access, MX Analyze, provides a variety of ways that your health plan can share and access member information based on your data sharing standards and technology.

With Manifest MedEx, health plans can:

  • Start concurrent review and coordinate care right away with admission, discharge, and transfer (ADT) notifications
  • Optimize utilization management and quickly learn new member medical histories with longitudinal patient records
  • Save time and reduce the burden of HEDIS® reporting with NCQA validated primary source data
  • Identify care gaps to improve quality
  • Simplify risk adjustment with easy-to-consume, clinical chart notes

NCQA Validated Data

With Manifest MedEx, the only data aggregator in California with NCQA validated data, health plans have access to standard supplemental data for Healthcare Effectiveness Data and Information Set (HEDIS®) reporting instead of needing to obtain it from individual providers on an at-need basis.

Without the need for any additional primary source verification, health plans reduce the time they spend assembling patient charts and confirming accurate data and instead dedicate more time and energy to supporting and caring for their members.

Putting MX Data to Work for Health Plans

Health plans across California utilize the Manifest MedEx network to accelerate time-to-value for members, improve care coordination, fuel quality improvement, and more. The health data provided by MX is a key resource for health plan teams to take quick action and provide responsive, personalized, and proactive care to members.

Through using MX, certain participating health plans have been able to:

  • Reduce outbound calls to hospitals by 15-20% per month
  • Reduce “chart chases” by 54%
  • Assess hundreds of records each month to perform concurrent reviews and provide authorizations for their members’ surgeries, scans, and more

“I am happy about the speed with which HPSJ and MX were able to create a comprehensive report to prioritize outreach to our members...We continue to find ways that the HIE can supplement and complement our efforts to ensure timely and effective care for our members.”

Cheron R. Vail, PhD
Chief Information Officer, Health Plan of San Joaquin

“I have seen firsthand how invaluable robust data-sharing can be. Each of our patients deserves the highest-quality care — which necessitates a high-quality data structure — so that nothing, and no one, falls through the cracks.”

Jarrod McNaughton
Chief Executive Officer, Inland Empire Health Plan

“Leveraging MX discharge data has enabled us to eliminate a really significant number of outbound calls to hospitals to confirm inpatient status. We’re leveraging all of the discharge data from the hospitals that are participating with MX. It’s already making such a big impact, and we’re just getting started.”
