What Health Insurance Usually Covers (With Conditions)

Surprise Exclusion: Many plans don’t cover medical care abroad, so travelers should consider supplemental insurance.

How to Maximize Your Health Insurance Benefits

1. Use In-Network Providers

  • Saves 40-60% vs out-of-network costs

  • Always verify network status (directories can be outdated)

2. Get Pre-Authorizations When Required

  • Needed for many:

    • MRIs/CT scans

    • Surgeries

    • Specialty medications

3. Understand Your Drug Formulary

  • Tier 1: Lowest copay (generics)

    • Therapeutic alternatives

    • Mail-order options

4. Track Your Deductible & Out-of-Pocket Max

  • Schedule expensive procedures after meeting deductible

  • Once you hit your out-of-pocket max, insurance pays 100%
