Before billing for a service you should consult with a local and trusted billing professional, the 2019 CPT code manual, and the insurance providers you are billing. Each insurance provider may have special requirements for telemental health services to be billed. This is especially true for Medicare and Medicaid.
When billing Medicare and Medicaid, if the clinician, client, and service are approved for telemental health services, the approved telehealth originating site (the site where the client is during the time of the session) can also bill for services.
You can find a list of the CY 2019 Medicare Telehealth Services, and CPT codes often reimbursed by insurance companies at this link.
This post is not meant to be legal advice, but it is very important information. Billing correctly is critical to running a professional telemental health practice. It is recommended to take your time to make sure you are billing telemental health services correctly.
