The core trade-off
HMOs trade flexibility for lower cost and coordinated care. PPOs cost more but let you see specialists and out-of-network providers with fewer restrictions.
Neither is universally better. The right choice depends on how often you travel, whether you have established specialists, and your tolerance for paperwork.
HMO strengths and limits
- Lower premiums and predictable copays on many plans
- Primary care doctor coordinates referrals and records
- Strong preventive care focus within network
- Usually no out-of-network coverage except emergencies
- Referral required for most specialist visits
PPO strengths and limits
- See specialists without referrals
- Partial coverage for out-of-network care
- Easier to keep doctors when moving within a region
- Higher premiums and deductibles than similar HMOs
- Out-of-network costs can add up quickly
How to decide in three questions
Do you have a specialist you cannot switch? Check whether they are in the HMO network. If not, a PPO or EPO may be necessary.
Do you split time between two states? PPO out-of-network access may matter. Do you rarely leave your metro area? An HMO could save money without limiting care.
Run the numbers for your actual prescriptions and expected visits. A cheaper HMO that excludes your drug is not a bargain.
