Your Medigap Open Enrollment Period runs 3 months before your 65th birthday through 3 months after — a 6-month window during which no insurance company can deny you coverage or charge you higher premiums based on your health. Miss this window and underwriting applies — permanently.

After this window, insurers can price based on your health. Premiums can be 30–50% higher — or you can be denied entirely.
Missing your Medicare Part B enrollment window causes permanent premium penalties. The Medigap window is separate but equally critical.
Without Medigap, Original Medicare leaves you exposed to unlimited 20% coinsurance. One serious illness can mean $20,000+ in bills.
