While each state is different, most have expanded coverage for telehealth due to COVID-19. Many are now matching Medicare’s telehealth coverage. Check your state’s current laws and reimbursement policies to see what is covered. For updates on COVID-19 reimbursement and related Medicaid codes and procedures for your state, see:

It is important to note that most states distinguish between reimbursement standards for permanent telehealth policies and temporary COVID-19 reimbursement policies.
