Balance Billing by Health Care Providers: Assessing Consumer Protections Across States.

ISSUE: Privately insured consumers expect that if they pay premiums and use in-network providers, their insurer will cover the cost of medically necessary care beyond their cost-sharing. However, when obtaining care at emergency departments and in-network hospitals, patients treated by an out-of-network provider may receive an unexpected "balance bill" for an amount beyond what the insurer paid. With no explicit federal protections against balance billing, some states have stepped in to protect consumers from this costly and confusing practice. GOAL: To better understand the scope of state laws to protect consumers from balance billing. METHODS: Analysis of laws in all 50 states and the District of Columbia and interviews with officials in eight states. FINDINGS AND CONCLUSIONS: Most states do not have laws that directly protect consumers from balance billing by an out-of-network provider for care delivered in an emergency department or in-network hospital. Of the 21 states offering protections, only six have a comprehensive approach to safeguarding consumers in both settings, and gaps remain even in these states. Because a federal policy solution might prove difficult, states may be better positioned in the short term to protect consumers.
