Medicare Advantage 2017 Spotlight: Enrollment Market Update

Key Findings
Key Findings:
- Enrollment Growth. Since the ACA was passed in 2010, Medicare Advantage enrollment has grown 71 percent. As of 2017, one in three people with Medicare (33% or 19.0 million beneficiaries) is enrolled in a Medicare Advantage plan.
- Market Concentration. UnitedHealthcare and Humana together account for 41 percent of enrollment in 2017; enrollment continues to be highly concentrated among a handful of firms, both nationally and in local markets. In 17 states, one company has more than half of all Medicare Advantage enrollment – an indicator that these markets may not be very competitive.
- Medicare Advantage Penetration. At least 40 percent of Medicare beneficiaries are enrolled in Medicare private plans in six states: CA, FL, HI, MN, OR, and PA. In contrast, fewer than 20 percent of Medicare beneficiaries are enrolled in Medicare Advantage plans in 13 states, plus the District of Columbia.
- Premiums and Cost-Sharing. While average Medicare Advantage premiums paid by MA-PD enrollees have been relatively stable for the past several years ($36 per month in 2017), enrollees may be liable for more of Medicare’s costs, with average out-of-pocket limits increasing 21 percent and average Part D drug deductibles increasing more than 9-fold since 2011; however, there was little change in out-of-pocket limits and Part D drug deductibles from 2016 to 2017.
This Data Spotlight reviews national and state-level Medicare Advantage enrollment trends as of March 2017 and examines variations in enrollment by plan type and firm. It analyzes the most recent data on premiums, out-of-pocket limits, and quality ratings.
