With COVID19 almost all rules involving telehealth have changed. And unfortunately they vary by carrier. The only resource I can point you to is the websites and bulletins that these carriers are putting out. Most carriers are reimbursing telehealth at the regular rates for in office services. Some are even waiving the patient responsibilities and paying the entire portion. They've also changed the rules as things progressed, since this situation is unprecedented. We have had to learn as we go, and be flexible in order to keep up with the changing guidelines. I'm sorry I don't have a better answer for you than that, but right now that's where we are at.
If anyone knows of any resources out there on this, please share!
