Mass HIway Frequently Asked Questions

Below are a few of the most frequently asked questions on the Mass HIway. 

Q. What is the Mass HIway?

The State-wide health information exchange, also known as the Massachusetts Health Information Highway (the Mass HIway), enables the electronic movement of health-related information among diverse organizations, such as doctors’ offices, hospitals, laboratories, pharmacies, skilled nursing facilities and health plans. The Mass HIway facilitates the exchange of clinical information among varied health care information systems, while maintaining the meaning of the information being exchanged, regardless of provider affiliation, location or differences in technology.

Note: The Mass HIway is not the health insurance exchange (HIX) – that is a separate program called the HealthConnector.

Q. Who can use the Mass HIway?

Currently, the Mass HIway is available to healthcare organizations which are involved in coordinating patient care, e.g. hospitals, medical practices, laboratories, pharmacies, long term care and behavioral health organizations, health plans. Eligible organizations must be a legal entity that is a Covered Entity or a Business Associate of a Covered Entity and may range from a solo practitioner to a large healthcare delivery system. In order to ensure that the Mass HIway provides a secure environment for participating organizations all potential users will go through a verification process by the state before their account is activated.

Q. How much does it cost to join the Mass HIway?

Participating organizations pay an annual fee for participation with the Mass HIway. The Mass HIway rate card describes the annual participation rate by tier and type of connection.

Q. Is the information I send over the Mass HIway secure?

Yes, information sent over the Mass HIway is private and secure. The Mass HIway has created, and enforces, a “trust fabric” – the set of technical security tools and approaches, and legal policies to which all participants must agree, e.g. Participation Agreement, Patient Consent. A message sent via the Mass HIway is encrypted so that it is readable only by the intended receiver. Even if someone were able to intercept a secure Mass HIway message, he/she would be unable to decrypt it or read it. The Mass HIway uses security best practices designed to keep health information private and secure. These practices are mandated by federal and state government and include physical, administrative and technical safeguards.

Q. How may the Mass HIway benefit my organization?

Currently, when doctors need to share health information about a patient with providers or institutions outside (or, even within) their organization, gathering and communicating patient health information can take hours or even days. Sometimes the information is missing or not available at all, leaving providers with an incomplete picture of a patient’s health status. Implementing the Mass HIway is a critical component to enabling the Commonwealth’s collective care community. Connected organizations and their providers will directly benefit from participating in the State-wide health information exchange and begin to:

  • Improve and streamline care coordination
  • Reduce medical errors/Improve patient safety
  • Reduce duplication
  • Support Meaningful Use achievement
  • Reduce costs throughout the care delivery system
  • Ease and improve public health reporting and analytics
  • Provide a foundation for accountable care organizations and value-based healthcare models
  • Enhance patient care communication among providers
  • Increase patient engagement with providers on care plans

Q. Is connecting to the Mass HIway required to achieve Meaningful Use Stage 2 in Massachusetts?

For Meaningful Use Stage 2, providers will be required to exchange EHR data with health care organizations as well as exchange patient data when care is transitioned from one provider to another. The Mass HIway team helps organizations and their providers understand the technical options available to securely exchange information on the Mass HIway to meet Meaningful Use requirements.
