Coverage, Plans, and Costs
Medicare Supplement Insurance — often called Medigap — helps cover the out-of-pocket costs left after Original Medicare (Parts A and B) pays its share. These plans are offered by private insurance companies and are designed to protect you from unexpected healthcare expenses like deductibles, copayments, and coinsurance.
With a Medigap plan, you can enjoy greater financial security and more predictable healthcare costs.
What Medicare Supplements Cover
Original Medicare covers a lot, but it doesn’t cover everything. Medicare Supplement plans help pay for the “gaps” in coverage, including:
Part A deductible and coinsurance (hospital costs)
Part B coinsurance and copayments (doctor visits, outpatient services)
Skilled nursing facility care coinsurance
First three pints of blood needed for a medical procedure
Foreign travel emergency care (up to plan limits)
Note: Medigap plans do not include prescription drug coverage (Part D), dental, vision, hearing, or long-term care.
Standardized Medicare Supplement Plans
Every Medigap policy is standardized by the federal government. Plan G from one company offers the same benefits as Plan G from another — only the price and customer service differ.
Medigap Plan | Key Benefits | Ideal For |
---|---|---|
Plan G | Covers everything except the Part B deductible | Most comprehensive coverage available for new enrollees |
Plan N | Lower premiums, small copays for office visits and ER visits | Those willing to trade small out-of-pocket costs for savings |
Plan A | Basic benefits, no Part A deductible coverage | People wanting minimum supplement coverage |
Plan F | Covers all Medicare-approved costs | Only available to those eligible before January 1, 2020 |
Important: Plan F is closed to new Medicare beneficiaries starting January 1, 2020, but existing enrollees can keep it.

How Much Does a Medicare Supplement Cost?
Medigap premiums vary based on:
Your age (attained-age, issue-age, or community-rated pricing models)
Location (costs are generally higher in some states)
Insurance company (same plan, different prices)
Gender (some states allow gender-based pricing)
Health conditions (especially after your guaranteed issue window)
Example Costs:
Plan G: Typically ranges from $100 to $300 per month.
Plan N: Slightly lower premiums, around $80 to $250 per month.
Tip: Always compare prices across multiple insurers — the benefits stay the same, but the cost doesn’t.
When Can You Enroll in a Medicare Supplement Plan?
The best time to enroll is during your Medigap Open Enrollment Period:
Starts: The month you’re both 65 or older and enrolled in Medicare Part B.
Lasts: 6 months.
Benefit: During this time, insurance companies cannot deny you coverage or charge you more based on health issues.
If you miss this window, you may have to pass medical underwriting to qualify.
