What happens if I see an out-of-network provider?
Coverage depends on your network type.
HMO
Out-of-network care is generally not covered except for emergencies.
PPO
Out-of-network care is usually covered, but your costs are typically higher.
EPO
Out-of-network care is generally not covered except for emergencies.
POS
Out-of-network care is generally covered, but you will usually pay more than you would for in-network care.
Which network type should I choose?
The best network type depends on your healthcare needs.
Consider:
Whether your preferred doctors are in-network
Whether you want specialist access without referrals
Whether you need out-of-network coverage
How much flexibility is important to you
Your monthly premium and out-of-pocket budget
There is no single best network type for everyone.
The right choice depends on your providers, healthcare usage, and budget.
