No two states are alike in how telehealth is defined and regulated. While there are some similarities in language, perhaps indicating states may have utilized existing verbiage from other states, noticeable differences exist. These differences are to be expected, given that each state defines its Medicaid policy parameters, but it also creates a confusing environment for telehealth participants to navigate, particularly when a health system or practitioner provides health care services in multiple states. In most cases, states have moved away from duplicating Medicare’s restrictive telehealth policy, with some reimbursing a wide range of practitioners and services, with little to no restrictions. One of the most common trends with live video reimbursement was the addition of eligible services to the list of telehealth eligible services, with applied behavioral analysis being the most common service addition mentioned in Medicaid manuals. Additionally, in the wake of the COVID-19 pandemic, some states do seem to be adopting the Center for Medicare and Medicaid Services (CMS) communication technology-based services (CTBS) codes, including the virtual check-in and remote evaluation of prerecorded information, audio-only service codes and remote physiologic monitoring. All fifty states and the District of Columbia have a definition in law, regulation, or their Medicaid program for telehealth, telemedicine, or both. Additionally, because of the allowance in most states to utilize telephone as a form of telehealth during COVID-19, some states are taking steps to broaden its permanent definitions of telehealth or telemedicine by removing the explicit exclusion of telephone or including audio-only services within the definition itself. One of the states with the most significant changes to their telehealth policy was Massachusetts which passed a comprehensive telehealth law to require reimbursement for both Medicaid and private payers if the services are covered in-person and it is appropriately delivered through telehealth. The law contained some unique elements including specifying that the rate of payment for telehealth services provided via interactive audio-video technology and audio-only telephone may be greater than the rate of payment for the same services delivered by other telehealth modalities. It also provided payment parity for in-network providers of behavioral health services delivered via interactive audio-video technology or audio-only telephone only.
