Medigap worth the cost is one of the most common questions among new Medicare beneficiaries. Original Medicare covers hospital stays and doctor visits. However, it leaves significant financial gaps. There is no annual out-of-pocket maximum under Original Medicare. The 20% Part B coinsurance applies to every approved service with no cap.
A single hospital stay triggers a Part A deductible of $1,736 per benefit period in 2026. Skilled nursing care adds $217 per day in coinsurance after the first 20 days. These expenses accumulate quickly for anyone managing chronic conditions or facing unexpected health events. Whether medigap worth the cost depends on your health, your budget, and your tolerance for financial risk. Roughly 12 million Americans already carry this coverage for protection against unpredictable medical bills.
What Original Medicare Does Not Cover
Original Medicare has two parts. Part A covers inpatient hospital care, skilled nursing, and hospice. Part B covers outpatient services, doctor visits, and durable medical equipment. Neither part covers everything you might need. Part B requires a $283 annual deductible in 2026. After meeting the deductible, you still pay 20% of every approved service. Unlike most employer health plans, there is no yearly limit on what you could owe out of pocket. A major illness could generate tens of thousands in cost-sharing.
Hospital stays carry even larger exposure. The Part A deductible resets with each benefit period, not just once per year. Days 61 through 90 in the hospital add $434 per day in coinsurance. Lifetime reserve days cost $868 per day. Additionally, doctors who do not accept Medicare assignment can charge up to 15% above the approved amount. These Part B excess charges come entirely out of your pocket without supplemental coverage. For many beneficiaries, understanding these gaps makes the question of medigap worth the cost much clearer.
How Medigap Plans Work and Which Plans Are Most Popular
Medicare Supplement plans are standardized by the federal government into 10 plan types. They are labeled A through N. Each letter covers a specific set of benefits. Plan G from AARP/UnitedHealthcare covers the same benefits as Plan G from Mutual of Omaha. The same applies to Blue Cross Blue Shield or any other licensed carrier. Price and customer service are the only differences between companies.
Plan G is the most popular choice among new enrollees. According to KFF research, 39% of all Medigap policyholders now hold Plan G. It covers the Part A deductible, all hospital and outpatient coinsurance, and Part B excess charges. You pay only the Part B annual deductible out of pocket. Plan F was the top option for years but closed to new enrollees in January 2020. Plan N offers lower premiums in exchange for small office visit copays and no excess charge coverage. The question of medigap worth the cost starts with understanding what each plan includes and excludes.
Typically, premiums vary significantly by state, age, and insurance company. Shopping among carriers like Aetna, Cigna, and Humana often reveals meaningful savings for identical benefits. High-deductible versions of Plan G also exist for beneficiaries comfortable with a higher upfront deductible in exchange for lower monthly payments.

Is Medigap Worth the Cost for Your Situation
The answer depends on your personal health and financial circumstances. Beneficiaries with chronic conditions or frequent specialist visits face the greatest exposure from the 20% Part B coinsurance. In most cases, a predictable monthly premium costs less than one unexpected hospital stay. About 43% of traditional Medicare beneficiaries already carry Medigap coverage, according to KFF. That percentage reflects a widespread conclusion that the financial protection justifies the monthly expense. Beneficiaries without any supplemental coverage bear the full weight of every deductible and coinsurance charge with no safety net.
Timing matters enormously. Your Medigap Open Enrollment Period lasts six months. It starts the month you turn 65 and enroll in Medicare Part B. During this window, insurers cannot deny you coverage. They cannot charge more for pre-existing conditions either. Once the window closes, companies can apply medical underwriting. They may reject your application entirely or set rates based on health history. For this reason, deciding whether medigap worth the cost is most critical during that initial six-month window.
Consider your alternatives as well. Medicare Advantage plans bundle hospital and outpatient coverage with annual out-of-pocket maximums. They also restrict you to specific provider networks. Medigap plans let you see any doctor who accepts Medicare anywhere in the country. Meanwhile, roughly 6 million traditional Medicare beneficiaries have no supplemental coverage at all. They face unlimited cost-sharing exposure every single year.

Frequently Asked Questions
Is medigap worth the cost if I am currently healthy?
Even healthy beneficiaries face risk from unexpected medical events. One surgery or hospital admission can generate thousands in coinsurance charges. For example, a single hospital stay in 2026 triggers a $1,736 Part A deductible before any daily coinsurance begins. Health changes quickly after 65, so locking in coverage during your Open Enrollment Period protects you regardless of future diagnoses.
Which Medigap plan offers the best overall value?
Plan G is the most popular option among new enrollees today. It covers nearly all out-of-pocket costs except the annual Part B deductible. Plan N may suit beneficiaries who prefer lower premiums and can accept small copays along with Part B excess charges. Comparing quotes from UnitedHealthcare, Mutual of Omaha, and Aetna reveals competitive rates for identical benefits. Your state insurance department or local SHIP counselor can help you compare plans side by side at no charge.
Can I buy a Medigap plan at any time of year?
Not without potential consequences. Your guaranteed-issue window lasts six months starting at age 65 with Part B enrollment. After that period, insurers in most states can use medical underwriting to set prices or deny coverage entirely. As a result, evaluating medigap worth the cost should happen well before your Open Enrollment window closes. Contact your state’s SHIP program or visit Medicare.gov for free guidance on timing and plan selection.
