Medigap costs vary depending on factors like your age, location, plan type, and insurer, but premiums typically range from $50 to over $300 per month. Prices can also increase over time based on how the plan is priced—community-rated, issue-age-rated, or attained-age-rated. To get an exact quote, it's best to compare plans from different insurers in your area.

The best Medigap plan depends on your healthcare needs and budget, but Plan G is often considered the most comprehensive for new enrollees, covering nearly all out-of-pocket costs except the Part B deductible. Plan N is a popular lower-cost option with small copays for doctor visits and emergency rooms. If you became eligible for Medicare before 2020, Plan F offers the most coverage, including the Part B deductible.

You need Medicare Part D if you want prescription drug coverage since Original Medicare and most Medigap plans don’t cover medications. Even if you don’t take prescriptions now, enrolling when first eligible helps you avoid late penalties and ensures coverage if you need it later. If you have other drug coverage, like from an employer or VA benefits, you may not need Part D.
