Frequently Asked Questions

What is a supplemental insurance agent in Costa Mesa?
A supplemental insurance agent is a licensed professional who helps you buy policies that cover gaps in primary health insurance, such as Medicare Supplement or critical illness plans. In California, agents must pass a state exam and complete continuing education to maintain their license.
How do I choose a supplemental insurance agent in Costa Mesa?
Look for an agent who is licensed with the California Department of Insurance and has experience with Medicare Supplement plans. You can verify an agents license on the CDI website. Ask about their familiarity with local hospitals and doctors in Orange County.
Are there California-specific rules for supplemental insurance?
Yes, California has a Medicare Supplement open enrollment period that starts when you turn 65 and enroll in Medicare Part B. During this time, insurers cannot deny you coverage or charge higher premiums due to pre-existing conditions. This is called guaranteed issue rights under California law.
