• States are encouraged to facilitate clinically appropriate care within the Medicaid program using telehealth technology to deliver services covered under the State plan. 
•  States have a great deal of flexibility with respect to covering Medicaid services provided via telehealth.  
• States are not required to submit a State plan amendment (SPA) to pay for telehealth services if payments for services furnished via telehealth are made in the same manner as when the service is furnished in a face-to-face setting. 
•  A state would need an approved State plan payment methodology (and thus, might need to submit a SPA) to establish rates or payment methodologies for telehealth services that differ from those applicable for the same services furnished in a face-to-face setting. 
• States may pay a qualified physician or other licensed practitioner at the distant site (the billing provider) and the state’s payment methodology may include costs associated with the time and resources spent facilitating care at the originating site. The billing provider may distribute the payment to the distant and originating sites. 
• Medicaid guidelines require all providers to practice within the scope of their State Practice Act. States should follow their state plan regarding payment to qualified Medicaid providers for telehealth services.
• States may also pay for appropriate ancillary costs, such as technical support, transmission charges, and equipment necessary for the delivery of telehealth services. A state would need an approved State plan payment methodology that specifies the ancillary costs and circumstances when those costs are payable.
• States are encouraged to reach out to their state lead as soon as possible if they are interested in submitting a state plan amendment.
