Mass HIway User Map

The Mass HIway User Map was developed by the Massachusetts eHealth Institute (MeHI) and is maintained monthly in partnership with the Mass HIway.

Provider organizations can use the Mass HIway User Map to determine which of their current trading partners are connected to the Mass HIway, but the Map, nor the Mass HIway, can provide details as to what types of messages the User is ready to receive. If your trading partner is on this list, contact that organization first before sending a message or document over the Mass HIway. Do not send a message to a User over the Mass HIway without coordinating with that User first to ensure readiness to receive.

Patients can use the Mass HIway User Map to see if their healthcare organizations are signed up to use the Mass HIway, then speak with providers or office staff at that healthcare organization to see if they are ready to use the Mass HIway in patient care. It's important to note, because this is a new tool, it may take time before all providers at a healthcare organization are ready to use it.
