Various smaller health insurance issuers have challenged the risk-adjustment program under the Patient Protection and Affordable Care Act (ACA), alleging, among other things, that its underlying methodology favors larger insurers. Last week the Fifth Circuit issued an opinion in one of those cases, affirming the lower court's rulings in favor of the United States Department of Health and Human Services (HHS) and its administration of the risk-adjustment program.

To effectuate the program, HHS created a three-step risk-adjustment methodology:
- First, for each individual enrolled in an insurer's plan an actuarial risk score is computed using demographic and diagnostic data to determine the predicted cost of insuring that enrollee (see 2014 Final Rule, 78 Fed. Reg 15,411 (March 11, 2013));
- Second, the risk scores for each enrollee in a plan are aggregated to determine the plan's average risk score (see id. at 15,432) and

In February 2018, a district court in New Mexico vacated HHS's risk-adjustment rules for benefit years 2014 through 2018 to the extent the rules relied on the...
