Creating a myD-H Account

Existing Patient Online users
  • If you already have a Patient Online (POL) account, you're all set! Just go to and log in using your POL username and password. If you’ve forgotten your POL username or password, just follow the steps below to request a one-time Activation Code to convert your POL account.
  • If you already have an account but got a message saying the username is taken, that's because myD-H merges what used to be separate POL systems for different Dartmouth-Hitchcock locations. In rare situations, more than one person may have chosen the same username in the old system. If this happens, the first user to sign into myD-H will continue to use the old username, but the next person will need to choose a new myD-H username. We apologize for any inconvenience.
New users
  • If you are a new patient, or a current patient who has never used POL, you can get a myD-H activation code during your next appointment with your provider, or you can request a code at
  • You will receive an email with your temporary access code at the address you provided during online registration. Your access code will allow you to login and create your own username and password.
  • If you have any difficulty getting an activation code, please contact Health Information Services.
Activation code

Your activation code is not your myD-H username or password. You will use your code only once to log in to myD-H for the first time. This code will expire after the first time you use it, or after 45 days if it has not been used. When you log in to myD-H for the first time, you will need to create a username and password.

For technical support, contact the myD-H Support Team. Please note that we cannot answer medical questions, so please contact your provider directly.
