Because Medigap plans are standardized, you can get precisely the same Medicare benefits from any company offering the plan. So when you shop, keep these considerations in mind to find the best policy to fit your needs:
Is your preferred plan available? Health insurance companies don’t always sell every plan, so check who sells the plan you want to buy in your area.
What are the premiums? Prices for the same plan can vary between companies, so check to find the most competitive rates.
Will your premiums change over time? Most policies cost more as you age, but some companies offer policies that let you lock in a price when you sign up.
Are there extras? Medigap plans’ core benefits are standardized, but in certain cases, some companies include such perks as discount programs or gym memberships.
If you have additional questions about Medicare, visit Medicare.gov or call 800-MEDICARE (800-633-4227, TTY 877-486-2048).
