- National plans continue to grab market share, with 850,000+ new enrollees in 2018. Enrollment growth within these plans is not universal, however, with United (7.85% growth) and Aetna (16.49% growth) leading the way while Anthem (3.78% growth) and Kaiser (0.33% growth) lag behind.
- Provider-sponsored and Blues plans especially struggled to attract new enrollment, with growth of 0.19% and 0.81% respectively.
- The distribution of market share by product type (network and segment combination) was relatively stable, with the exception of EGHP PPO which captured an additional 1.37% in market share. This growth was fueled by increases in enrollment for Aetna (160K), United (150K), and BlueCross BlueShield of Michigan (54K).
- PPO (4.10%) and HMO (4.00%) products grew at very similar rates in the Individual market, but with HMO products having substantially more enrollment overall (9.8M to 3.6M).
- Market growth by geography varied wildly with states like Michigan (10.88%) and Texas (9.15%) growing substantially while some rural, Western states like Montana (-11.40%) and South Dakota (1.30%) lost enrollment or grew slowly.
