Financing and regulating healthcare in the United States is complicated. Fortunately, actuaries understand the intricacies and can provide unique perspectives to address the system’s complex challenges. In the article “Healthcare: It’s complicated,” Milliman’s Hans Leida and Lindsy Kotecki discuss issues related to reform which actuaries have helped navigate.
Here is an excerpt:
Besides predictability problems caused by regulatory or political factors, two challenges facing health actuaries during these transitional years have been (1) the lag between when market changes are implemented and when data on policies subject to the new rules becomes available, and (2) the difficulty in predicting consumer behaviour in reaction to major changes in market rules such as guaranteed issue and community rating. How many of the uninsured would sign up? How price-sensitive would members be when they renewed their coverage each year? How will changes in other sources of coverage (such as Medicaid expansion) impact the individual market? How will potential actions by competitors affect an insurer’s risk?
Despite the daunting nature of these challenges, actuaries have, out of necessity, found ways to try to address them. For example, faced with the data lag problem, they explored ways to augment traditional claim and enrollment data with new data sources such as marketing databases or pharmacy history data available for purchase. Such sources can be used to develop estimates of the health status of new populations not previously covered by an insurer. Many actuaries also developed agent-based stochastic simulation models that attempted to model the behaviour of consumers, insurers and other stakeholders in these new markets. Such models continue to be used to evaluate the potential outcomes of future changes to the healthcare system, and will probably be essential should efforts to repeal and replace the ACA prove successful.
