A monthly roundup of news and updates from MX

December 2021 Edition

MX Banner Year in Network Growth and
Expanding Health Information Exchange


As 2021 comes to a close, we are proud to share our progress this year in growing and facilitating health information exchange throughout California so that our participants can do the hard work of supporting better patient care and keeping our communities healthy and thriving, even as the pandemic endures.

After a year of record growth, today we share health data for more than 28 million Californians across the state, and it’s all thanks to our participants who make this data exchange possible.

This year, with the help of Cal-HOP, we welcomed more than 800 new provider participants, including our largest health system partner, Adventist Health. Four health plans – Aetna, Central Valley Health Plan, Gold Coast Health Plan, and Inter Valley Health Plan – also joined our network. We now share data across more than 125 hospitals, 1500 ambulatory providers, and 10 plans throughout the state.

As a result of this network expansion, we’ve increased clinical data (CCDAs) sharing by 239 percent and lab data by 172 percent this year. On a monthly basis, we generate more than 1 million admission, discharge, and transfer (ADT) notifications, an increase of 237 percent from 2020 – each representing an opportunity to better coordinate care for a patient.

As we head into the holidays and new year, we want to take this moment to thank our participants for supporting the expansion of health data exchange as we strive to achieve our mission to provide every healthcare organization in California with the information they need to improve care, enhance health, and lower costs.

We look forward to our continued partnership in 2022 and beyond. Together, we can help give Californians the care they deserve.

Participant Bright Spot

Located in the heart of California’s multicultural Central Valley, Health Plan of San Joaquin (HPSJ) is the leading Medi-Cal managed care provider in the region, serving over 91 percent of Medi-Cal recipients in San Joaquin County and over 70 percent in Stanislaus County. As a not-for-profit, public health plan, HPSJ provides access to high-quality, cost-effective health care to its 384,000 members, who are mostly working families and children, as well as seniors and disabled residents.

HPSJ turned to its partner Manifest MedEx (MX) to help support their proactive vaccination efforts and target their highest-risk and underserved members. HPSJ has partnered with MX and its local affiliate San Joaquin Community Health Information Exchange (SJCHIE) for more than five years.

NCQA Data Aggregator Validation Program

Manifest MedEx (MX) announced today that it has earned the Validated Data Stream designation in the new National Committee for Quality Assurance (NCQA) Data Aggregator Validation program. This marks the second consecutive year that MX’s clinical data has passed the rigorous validation process from NCQA. This means that health plans can again use validated data from Manifest MedEx for Healthcare Effectiveness Data and Information Set (HEDIS®) reporting, without needing to obtain the data from individual providers and validating the data.

Data Exchange Framework Stakeholder Advisory Group Meeting Recap

This week, the California Health and Human Services Agency (CalHHS) held their fourth Data Exchange Framework (DxF) Stakeholder Advisory Group meeting, which specifically focused on gaps and opportunities related to health information technology (HIT). Most of the discussion revolved around funding to close these critical technical infrastructure gaps.

At Manifest MedEx, we are thrilled to see the Advisory Group’s support for the opportunities presented around expanding data exchange capacity (#2) and event notifications (#3). As California’s largest nonprofit health data network, these are areas where we have the depth and breadth of experience in what works – and what doesn’t. For a full recap, please visit our website.

As we approach the halfway mark to these meetings (total of nine), we look forward to the DxF and California Health and Human Services Agency (CalHHS) progress on these fronts and will continue to represent our HIE participants and HIE community, sharing updates from the front line. The Advisory Group convenes again in the new year on January 13, 2022 from 10:00 AM to 12:30 PM. We invite you to follow @ManifestMedEx on Twitter for live tweets, share your thoughts, and stay tuned for more updates!

MX Portal Updates in 2022

Update to the Authorized User Confidentiality Agreement

Users of the MX portal are required to agree to the Authorized User Confidentiality Agreement to maintain the confidentiality, security, and integrity of protected health information and other patient information. To help save time and go green, we are pleased to announce that users can now review and accept the Confidentiality Agreement electronically upon logging into the MX portal, eliminating the need for paper copies.

The MX portal will automatically prompt users to re-review and acknowledge the Agreement on their annual renewal date.  If any changes are made to the Agreement before a user’s annual renewal date, the user will be prompted to review and accept the updated Agreement.
