The short answer is yes! For now.
In light of the current coronavirus crisis, the US department of Health and Human services has allowed patients and doctors to connect over a select group of encrypted services like Apple FaceTime, Facebook Messenger video chat, Google Hangouts video, or Skype.
Prior to the current coronavirus pandemic, doctors were required to use a secure encrypted video chat service to discuss a patient’s health issues. All video chats were required to meet HIPAA compliance, which is a set of standards for health information security. The policies were changed for coronavirus, however, so that patients could safely practice social distancing while still remaining connected to their doctors and able to have their everyday health concerns tended to.
