As state and federal regulators increase their focus on the enforcement of mental health and addiction parity laws, nonquantitative treatment limitations have emerged as a key trouble area for some health plans. This report provides a quantitative approach to investigating nonquantitative treatment limitations. It focuses on two quantitative analyses: (1) out-of-network utilization rates for inpatient and outpatient facility services as well as professional office visits and (2) reimbursement rates for office visits for in-network healthcare providers. The report includes appendices that provide detailed results for each state, including sample sizes, for 2013 to 2015.
