3 Questions to Ask Before You Buy a Medigap Plan in San Diego
1. How many carriers is this agent appointed with?
Not every agent who sells Medicare Supplement insurance in San Diego is independent. Some represent only a single carrier, which means they cannot show you the full range of available rates. Ask any agent upfront: "How many Medicare Supplement companies are you appointed with?" An independent broker typically works with five or more insurers and can present competing quotes in a single conversation. The wider the carrier panel, the better your odds of finding the lowest available premium for your plan of choice.
2. What has this carrier's rate increase history been over the past five years?
The lowest premium today does not guarantee the lowest cost over time. California law requires insurers to file rate increases with the California Department of Insurance (CDI), and those filings are a matter of public record. Ask your agent to share the recent rate-increase history for each carrier they are recommending. A carrier with a pattern of large annual increases may cost more in the long run than a competitor with a slightly higher starting premium but more stable pricing.
3. Is this plan community-rated, issue-age-rated, or attained-age-rated?
California is one of a small number of states that requires Medicare Supplement insurers to offer community-rated or issue-age-rated pricing, which generally means your premium will not automatically rise just because you get older. The California Department of Insurance (CDI) oversees Medigap policy filings in the state; you can reach the CDI at 1-800-927-4357 or visit insurance.ca.gov to verify a carrier's license or file a complaint. Understanding your plan's rating method helps you project long-term costs and compare carriers on an apples-to-apples basis.
