What this means
If you're a patientLook for a notice letter from the practice. Watch insurance statements for services
you didn't receive, and consider a free credit freeze with the three bureaus.
If you run a practiceCheck whether you share software, IT providers or billing vendors named in this
record. Confirm your own backups, remote access and email protections with your IT
provider.
