How to Choose the Right Supplemental Plan

• Worried about cancer/heart disease? → Critical illness

• Need dental/vision? → Standalone plan

Step 2: Compare Costs & Payouts

• Does the payout justify the premium?

• Are there waiting periods? (e.g., 6 months for cancer coverage)

Step 3: Check Provider Networks

• Some plans (like dental) require in-network providers

Step 4: Read Reviews

• Look at BBB ratings and customer complaints

Common Mistakes to Avoid

🚫 Assuming Medicare covers everything (it doesn’t—Medigap helps!)
🚫 Overlapping coverage (don’t buy two accident plans)
🚫 Ignoring pre-existing condition exclusions
🚫 Missing open enrollment for Medigap (best time is when you first get Medicare)

Missing enrollment deadlines → Lifetime penalties

Assuming Medicare covers everything (no long-term care, most dental)

Not reviewing your plan annually (benefits change yearly!)
