FAQ
How and when can I switch health insurers?
If you get coverage through an employer, you usually switch during annual open enrollment or after a qualifying life event. For individual coverage, use the ACA marketplace during open enrollment or a special enrollment period. Confirm your doctors and medications are covered under the new plan before switching.
Will a new insurer be less likely to deny my care?
No insurer guarantees approvals, but integrated systems like Kaiser and plans with strong quality ratings can mean smoother authorizations. Always review the plan's prior-authorization rules and provider network for the care you actually use, rather than choosing on premium alone.
What can I do when my insurer wrongly denies a claim?
File an internal appeal in writing and request the specific clinical reason for denial. If denied again, you have the right to an external independent review. For unresolved problems, contact your state's insurance commissioner (the proper regulator for insurance), and you can also use the Better Business Bureau (bbb.org). Note the CFPB handles financial products, not health insurance.
