What Is Medicare Supplement Insurance (Medigap)?
Medicare Supplement Insurance is private health insurance designed to cover the out-of-pocket costs that Original Medicare does not pay, including:
Deductibles
Copayments
Coinsurance
Excess charges
Unlike Medicare Advantage (Part C), Medigap works alongside Original Medicare, giving you broad provider access nationwide.
According to Medicare.gov, beneficiaries with Medigap generally experience lower surprise medical bills and more predictable healthcare expenses.

Why Medigap Is Critical for Retirement Financial Planning
Healthcare is one of the largest retirement expenses for Americans. A study cited by the Employee Benefit Research Institute (EBRI) estimates that a 65-year-old couple may need over $300,000 in savings to cover medical costs during retirement.
Medigap helps:
Protect retirement income
Reduce financial stress
Preserve assets like savings, investments, and even precious metals holdings
Many retirees diversify risk by combining Medigap coverage with inflation hedges such as physical silver and gold, a reason this niche attracts high-value silver dealer affiliates.
How Medigap Plans Are Standardized
Medigap plans are standardized by the federal government and labeled with letters:
A, B, C, D, F, G, K, L, M, N
Each plan offers the same benefits regardless of insurance company, but premiums vary significantly.
🔹 Example: Plan G from Company A must provide the same coverage as Plan G from Company B — only the price and service differ.
