For Our Future

In our healthcare system, 65% of data belonging to patients is siloed, unstructured and is held in different forms across patient care, research and payment ecosystems. — Source: Health Information Technology Advisory Committee (HITAC)
Today, a consistent patient health story is nearly impossible to track and share because data are unreliable, lack standardization, and are largely unusable. CodeX is the only member-driven community focused on solving the problem of silos endemic to our current healthcare system for specialty health data. We enable high-quality computable data — using Health Level Seven International (HL7) and Fast Healthcare Interoperability Resource (FHIR) standards — to create an open common language for patients, care teams, and researchers to advance data ownership, sharing, and reliability.

Building data unity

for patients, clinicians, and research.

Common data definitions drive high-quality computable data that are trusted, consistent, and usable.

Caring for Every Patient

Break down silos and manual processes for efficient care and research across all settings, building trust with your care team and accurate data.

Learning with Every Patient

Create easily accessible, accurate, and longitudinal patient stories that caregivers can use to personalize treatment and care.

Transforming Care for All

Revolutionize healthcare and research by leveraging standardized data of individual patients to contribute to the health of all future patients.

People's lives are depending on what we do and what these data tell us

Health Data.

Collect Once,

Use Everywhere.

CodeX is a global community of healthcare stakeholders currently working on data standards in three domains. We build and implement in the field and on-site.

Data elements of patient connected together in a digital format.


The first domain that the CodeX community tackled is cancer. Using the minimal Common Oncology Data Elements (mCODE), an open data standard enabling high-quality data capture for cancer that can be widely adopted.

70+ oncology elements in use at Dana-Farber Cancer Institute, MD Anderson Center, Massachusetts General Hospital and 45 other institutions. Versions of the mCODE and associated modeling tools are currently operational in over 250 organizations.

Our Traction

Since 2019, CodeX has been working in partnership with our community, building interoperable systems to positively impact the lives of real patients.


External Sources of Funding

The CodeX Community

The CodeX Community stakeholder map which includes patients, researchers, providers, payers, pharmaceuticals, health systems, public health, advocacy groups, global community, health IT, regulators, and philanthropy.


Growing a high-resolution longitudinal health record with easier access to care, research, clinical trials, and your health data.


Improving care continuity with standards-based clinical specialty data, spending more time on care than administration.

Health Centers

Assuring efficient, interoperable data exchange and reporting, and improved patient and care team satisfaction.

Pharma and Life Science

Increasing diversity and accessibility in clinical trial enrollment, improving treatment and drug safety monitoring.

Health IT

Removing data inaccuracies by embedding structured CodeX data in real-world innovative solutions.


Improving diversity and equity in clinical research with improved trial matching, common data sets, and targeted population research.


Advancing healthcare policy decisions with timely, high-quality data in registries and adverse events reporting.


Building collective impact to accelerate health equity, research, and care outcomes.

Public Health

Assuring real-time public health data and solutions for diverse populations across care and research settings.


Gaining insights to drive effective value-based care models and fraud reduction.

Advocacy Groups

Mobilizing efforts by understanding the healthcare and research needs and challenges in the communities you serve.

Global Community

Growing a global learning health system through open-standards clinical specialty data.

Use Case Spotlight:


Clinical trials are the gold standard for clinical care interventions. 92% of cancer patients in the United States are not enrolled in clinical trials due to poor data collection of their cancer therapies. This project focuses on collecting key outcome data that is standardized, research-grade, and longitudinal across organizations to promote health equity and reduce burden on health sites. This novel approach to data collection has already been adopted by over 13 health sites.
