For more than four decades, the Massachusetts Health Data Consortium (MHDC) has been the trusted and objective facilitator of health information and technology transformation in Massachusetts and across the country. With our merger with the New England Healthcare Exchange Network or NEHEN, we provide a range of health data innovations, insights, and services to over 4,000 health professionals across more than 200 organizations. Our mission is to inform and empower the individual in their health journey and reduce the burden healthcare imposes on patients and their families, providers, and payers. We realize this mission by assisting health organizations in navigating regulations, sharing health data securely and effectively, and reducing the burden and cost of inefficiency.
