Also attach scanned copies of the following documents, or they can be faxed to 832-553-1889.

  • State license paperwork
  • DEA paperwork
  • NPI paperwork. If you do not have a copy of your NPI paperwork, see https://npiregistry.cms.hhs.gov/
  • State ID (e.g. driver’s license) in color or grayscale. Black and white is not permitted.


Once credentials have been submitted, it will take approximately 48 hours to finalize. You will receive a confirmation email from Open Dental. We will then activate electronic transmission of prescriptions on your account and apply the one-time identity proofing fee to your statement.
