Researching on how to bill for Telemedicine is confusing me. I'm seeing two different ways to do it. One is billing CPT codes 99421-99423. I don't know if my brain is on overload but I'm also seeing this from CMS:

TELEHEALTH SERVICES BILLING AND PAYMENT
Submit professional telehealth service claims using the appropriate CPT or HCPCS code.
If you performed telehealth services “through an asynchronous telecommunications system”, add the
telehealth GQ modifier with the professional service CPT or HCPCS code (for example, 99201 GQ).
You are certifying the asynchronous medical file was collected and transmitted to you at the distant
site from a Federal telemedicine demonstration project conducted in Alaska or Hawaii.
Submit telehealth services claims, using Place of Service (POS) 02-Telehealth, to indicate you
furnished the billed service as a professional telehealth service from a distant site. As of January 1,
2018, distant site practitioners billing telehealth services under the CAH Optional Payment Method II
must submit institutional claims using the GT modifier.
Bill covered telehealth services to your Medicare Administrative Contractor (MAC). They pay you
the appropriate telehealth services amount under the Medicare Physician Fee Schedule (PFS). If
you are located in, and you reassigned your billing rights to, a CAH and elected the Optional Payment
Method II for outpatients, the CAH bills the telehealth services to the MAC. The payment is 80 percent
of the Medicare PFS facility amount for the distant site service.
TELEHEALTH ORIGINATING SITES BILLING AND PAYMENT
HCPCS Code Q3014 describes the Medicare telehealth originating sites facility fee. Bill your MAC for
the separately billable Part B originating site facility fee.
Note: The originating site facility fee does not count toward the number of services used to determine
payment for partial hospitalization services when a CMHC serves as an originating site.

I understand the modifier and place of service code, but what CPT codes do we bill? 99421-99423 or 99212-99214?
