The HIway Connections Map shows the provider organizations that are connected to the Mass HIway.
The Mass HIway cannot provide details as to what types of messages the organizations listed can receive. Before sending messages to another organization over the HIway, first coordinate whether they are ready to receive those messages.
Patients can use this information to see if their healthcare organizations are signed up to use the Mass HIway. Speak with the providers or office staff at that healthcare organization to see if they are ready to use the HIway in patient care. It may take time before all care providers at an organization that is connected to the Mass HIway are ready to use the HIway.
