According to the lecture, which entity frequently became the leader in HIE through RHIO development on a state level?

• A. Insurance companies
• B. Medicaid programs
• C. Physicians
• D. Federally funded research groups

Answer: (B)

Medicaid programs are frequently the leaders in state-level RHIO development because they sit at the intersection of funding, policy, and data. They administer the largest public payer program and have broad access to administrative data such as claims and eligibility encounters, which are essential for building and evaluating an HIE. With state-level authority and funding, they can convene diverse stakeholders—hospitals, physicians, public health, and other payers—and set standards, governance, and participation requirements that scale across the entire state. While insurers, physicians, and research groups may contribute in various ways, Medicaid programs possess the combination of data access, funding leverage, and regulatory authority that makes them the most common leaders of statewide HIE efforts.
