Financial Stability and Market Presence
Look for insurers with strong financial foundations. Market leaders like UnitedHealth Group, Elevance Health, and CVS/Aetna have proven track records, but smaller regional insurers might offer more personalized service or better local networks.

Consider these key financial aspects:
-
Monthly premiums
-
Annual deductibles (averaging $3,631 for Silver plans)
