Anthem offers four Medicare Advantage plan types for 2026, but its lineup is not evenly distributed across states. California gets only HMO-POS plans. Indiana has the widest selection, with plans across four types. Anthem structures its market around the plan type where its pricing advantage is strongest and adds broader coverage in areas with stronger provider networks.
Members in states with only one plan type are effectively choosing between Anthem and a competitor, not between Anthem plan types. Federal mandates for 2026 require behavioral health cost-sharing to match or improve upon Original Medicare. Insulin costs are capped with no deductible and members enrolled in the Medicare Prescription Payment Plan are automatically re-enrolled each year unless they opt out
- HMO: Anthem HMO plans require you to choose a primary care doctor who coordinates all care and authorizes specialist visits. Coverage is limited to in-network providers except in emergencies.
- HMO-POS: Anthem HMO-POS plans keep the primary care doctor and referral requirements for in-network specialists but allow out-of-network visits for certain services at higher cost.
- PPO: Anthem PPO plans require no primary care physician and no specialist referrals. You can see any Medicare-accepting provider. In-network visits cost less and out-of-network care is covered at higher rates.
- Regional PPO: Anthem Regional PPO plans extend coverage across multiple states with full PPO flexibility, useful for members who travel frequently or split time between states.
