How to Pick the Right One for You
Don't just go with the biggest name. Use these 4 questions:
- Are MY doctors in their network? A "great" insurer doesn't help if your doctor isn't covered.
- Are MY medications on their formulary at a reasonable tier? Drug pricing varies wildly between carriers.
- What's the actual TOTAL cost for me? Premium + expected deductible + copays for your typical year.
- What's their claim approval rate? Some carriers deny 15%+ of in-network claims initially. ProPublica publishes this data.
Where to Verify Quality
- NCQA ratings: National Committee for Quality Assurance — rates plans 1–5 stars
- JD Power surveys: Customer satisfaction by region
- State insurance department complaint ratios
- AM Best ratings: Financial strength of the insurer
