Below are answers to common questions about Medigap coverage in Connecticut.

MoneyGeek collected data for all Medicare plans in Connecticut for 65-year-olds and 75-year-olds, using the plan browsing tool at Medicare.gov. Unless otherwise noted, the data in this article references quotes pulled for 65-year-olds in the state.

We scored Medigap companies in Connecticut based on three main categories to create a weighted score out of 5:

• Affordability (50%): Providers with the lowest monthly cost score higher.
• Pricing style (20%): Medigap insurers use three methods to determine premiums: Community Pricing, Issue-Age Pricing and Attained Age Pricing. We gave higher scores for pricing styles that are more stable and equitable, as follows: Community Pricing 1.0, Issue-Age Pricing 0.8, Attained-Age Pricing 0.6. Using this scaling, a slightly higher-cost community-rated plan can still score higher overall than a cheaper but more volatile attained-age plan.
• Plan availability (30%): Providers with a wider range of plan types score higher, with weighted scoring given to the most popular plan types like Plan G, Plan F and Plan N.
