Anthem's 4.2 score is built primarily on its HMO plans. An HMO assigns you a primary care doctor who coordinates your care and refers you to specialists. You can only see providers inside Anthem's network, which keeps costs lower. That's why HMO averages $683 a month and Anthem's PPO, which allows out-of-network care at higher cost, averages $874.
For Medicare Advantage shoppers, Anthem's picture is weaker. CMS rates these plans from 1 to 5 stars on care quality and member satisfaction, with 4 stars or above considered strong. Anthem averaged 3.63 stars for 2026 and lost roughly 368,000 Medicare Advantage members that year, a decline that reflects those quality concerns.
