Which Medicare Supplement Plan Is Best?

Understanding Your Medicare Supplement Options

When you're enrolling in Original Medicare, you'll quickly discover that Medicare doesn't cover everything. Medicare Supplement Insurance (also called Medigap) helps fill these gaps by covering copayments, coinsurance, and deductibles that Original Medicare doesn't pay.

While there are 10 standardized Medigap plans, three plans dominate the market for new Medicare beneficiaries: Plan G, Plan N, and High-Deductible Plan G. Each offers different trade-offs between monthly premiums and out-of-pocket costs.

Comparing Plan G, Plan N, and High-Deductible Plan G

Most Popular: Plan G

Plan G is the most comprehensive Medigap plan available to new Medicare beneficiaries. It covers everything except the Part B deductible ($283 in 2026). After you pay that deductible, Plan G pays 100% of Medicare-approved costs with no copays or coinsurance.

What Plan G Covers:

• Part A coinsurance and hospital costs (up to 365 additional days after Medicare benefits end)
• Part A deductible ($1,736 in 2026)
• Part A hospice coinsurance
• Part B coinsurance or copayment (100%)
• Part B excess charges (when doctors charge more than Medicare-approved amounts)
• Blood (first 3 pints)
• Skilled nursing facility coinsurance ($217/day for days 21-100)
• Foreign travel emergency coverage (up to plan limits)

Plan G Costs

Plan G typically costs $150–$250 per month depending on your location, age, gender, tobacco use, and insurance carrier. In Alabama, rates tend to be on the lower end of this spectrum, especially in rural areas.

Who Should Choose Plan G

Plan G is ideal if you:

• Want predictable, comprehensive coverage
• Don't want to worry about copays or medical bills
• See doctors frequently or have chronic conditions
• Prefer peace of mind over saving on premiums
• Want protection against Part B excess charges

Budget-Friendly: Plan N

Plan N has lower premiums than Plan G (typically $100–$180 per month) but requires small copays: up to $20 for office visits and up to $50 for ER visits (waived if admitted). You also pay Part B excess charges if your doctor doesn't accept Medicare assignment.

What Makes Plan N Different

Plan N covers the same benefits as Plan G, except:

• Office visit copays: Up to $20 per visit
• Emergency room copays: Up to $50 per visit (waived if admitted)
• Part B excess charges: Not covered (you pay the difference if your doctor charges more than Medicare-approved amounts)

Plan N Costs

When Plan N Makes Sense

Plan N is the right choice if you:

• Are generally healthy and don't visit doctors frequently
• Want to save $500–$1,000+ per year in premiums
• Are comfortable budgeting for occasional copays
• Choose doctors who accept Medicare assignment (avoiding excess charges)
• Value lower fixed costs over maximum coverage

High-Deductible Plan G

High-Deductible Plan G has very low monthly premiums (often $40–$70) but requires you to pay a high deductible ($2,950 in 2026) before coverage kicks in. After you meet the deductible, it pays 100% of Medicare-approved costs—just like regular Plan G.

How High-Deductible Plan G Works

• You pay all Medicare-approved costs out-of-pocket until you reach $2,950
• Once you hit the deductible, the plan covers 100% of Medicare-approved costs
• The deductible resets each calendar year

What Counts Toward the Deductible:

• Part A hospital costs and deductibles
• Part B coinsurance and deductibles
• Doctor visits, lab work, medical equipment
• Part B excess charges
• Skilled nursing facility coinsurance

High-Deductible Plan G Costs

The Smart Strategy: Add Supplemental Coverage to High-Deductible Plan G

Here's where High-Deductible Plan G becomes truly powerful: by pairing it with affordable supplemental policies, you can create comprehensive protection that costs less than Plan G—both now and in the long term.

Why Add CHAS and HIP?

These supplemental policies fill the gaps that Medicare doesn't cover, and they offer unique advantages:

Cancer/Heart Attack & Stroke (CHAS) Policy Benefits:

• Lump-sum cash payment upon diagnosis (typically $5,000-$25,000)
• Money is yours to use however you need—pay your deductible, cover travel to specialists, replace lost income, pay for experimental treatments not covered by Medicare
• Covers conditions that account for the majority of serious health events
• Premiums are stable and rarely increase over time

Hospital Indemnity Plan (HIP) Benefits:

• Fixed daily benefit for each day hospitalized (typically $100-300/day)
• Pays regardless of other coverage—stacks with your Medigap plan
• Helps offset your deductible while you're recovering
• Can be used for any expense—medical bills, household help, lost wages
• Premiums remain stable with minimal increases

Real-World Cost Comparison

Let's look at what you actually pay over time:

Scenario 1: You Stay Healthy (Most Years)

Even in a healthy year, HD Plan G + supplemental coverage saves you $183-823 compared to Plan G.

Scenario 2: Cancer Diagnosis

With the supplemental coverage, you receive a $10,000 lump sum payment, giving you a net gain of $5,790 after all expenses.

Scenario 3: Major Hospitalization (7 days)

The Hospital Indemnity Plan significantly reduces your out-of-pocket costs, and you're still competitive with traditional plans.

Why This Strategy Wins Long-Term

Premium Stability: CHAS and HIP policies have remarkably stable premiums compared to traditional Medigap plans. While Plan G premiums increase 5-8% annually as you age, supplemental policies typically increase only 2-3% per year.

10-Year Cost Projection (Age 65 to 75):

You save $11,000-$16,000 over 10 years—even if you never use the supplemental benefits.

Who Should Choose High-Deductible Plan G + Supplemental Coverage

This strategy is ideal if you:

• Want comprehensive protection at the lowest total cost
• Are healthy now but want protection against serious illness
• Have $3,000 in emergency savings for the deductible
• Want cash benefits you control, not just claims reimbursement
• Value long-term premium stability
• Have family history of cancer, heart disease, or stroke
• Want the best value for your Medicare dollar
• Prefer lower fixed costs with catastrophic protection

Side-by-Side Cost Analysis

Scenario 1: Minimal Healthcare Use (Most Years)

Annual costs beyond premiums: ~$1,000

Winner: High-Deductible Plan G alone (saves $423–$783)
Best Value: HD Plan G + Supplemental (saves $183–$823 with superior protection)

Scenario 2: Moderate Healthcare Use

Annual costs beyond premiums: ~$5,000

Winner: Plan G and Plan N tied (both ~$767 less than HD Plan G alone)
Note: With hospitalization, HIP benefits reduce HD Plan G costs significantly

Scenario 3: Cancer Diagnosis with Treatment

Annual costs beyond premiums: $15,000+

Winner: HD Plan G + Supplemental Coverage by a landslide (you receive more in benefits than you pay out)

Scenario 4: Major Hospitalization (7-14 days)

Part A deductible + coinsurance

Winner: HD Plan G + Supplemental Coverage (saves $233–$1,033 vs. traditional plans)

How to Choose the Right Plan

Beyond Price: Other Factors to Consider

Insurance Carrier Stability

Choose a carrier with:

• Strong financial ratings (A.M. Best rating of A or higher)
• Good customer service reputation
• Claims processing efficiency
• Long-term stability in the Medicare Supplement market

Rate Increase History

Ask about:

• Historical rate increases for your age group
• Company's overall rate increase trends
• Whether rates are community-rated, issue-age-rated, or attained-age-rated
• For supplemental policies, verify their history of stable premiums

Household Discounts

Some carriers offer discounts if:

• Both spouses enroll with the same company
• You pay annually instead of monthly
• You're enrolled in automatic payment

Plan Flexibility

Consider:

• Your ability to switch plans during open enrollment
• Whether you might want to change plans as your health changes
• State-specific rules about guaranteed issue rights

Common Questions About Choosing a Medigap Plan

Can I switch plans later?

Yes, but it depends on your state's rules. In Alabama, you can apply to switch anytime, but insurance companies can use medical underwriting (except during certain guaranteed issue periods). This means if your health has declined, you might not qualify for a new plan or could face higher rates.

When is the best time to enroll?

Your Medigap Open Enrollment Period starts the month you turn 65 AND are enrolled in Medicare Part B. During this 6-month window, insurance companies cannot deny you coverage or charge you more due to pre-existing conditions. This is the best time to get the plan you want at the best rate.

Do all insurance companies charge the same for the same plan?

No! Medigap plans are standardized (Plan G from Company A covers the same things as Plan G from Company B), but premiums vary widely by company. That's why it's important to compare quotes from multiple carriers.

What's the difference between attained-age, issue-age, and community-rated pricing?

• Attained-age: Premium increases as you get older (most common)
• Issue-age: Premium based on age when you first buy (stays level)
• Community-rated: Everyone pays the same regardless of age (rare)

Most plans in Alabama use attained-age pricing, which means your premium will increase each year as you age, plus adjustments for inflation and healthcare costs.

Why would I add supplemental coverage instead of just buying Plan G?

Adding CHAS and HIP policies to High-Deductible Plan G gives you comprehensive protection at a lower total cost—both now and over the long term. These supplemental policies have stable premiums that rarely increase, unlike traditional Medigap plans that see 5-8% annual rate hikes. Plus, they pay cash benefits directly to you for serious health events, giving you financial control that traditional plans don't offer. Over 10 years, you'll save $10,000-$16,000 compared to Plan G, even if you never file a claim.

Are CHAS and HIP policies complicated to manage?

No! These are simple policies with straightforward benefits. When you're diagnosed with a covered condition (CHAS) or hospitalized (HIP), you file a claim and receive a check. There's no coordination with Medicare or your Medigap plan—the benefits are paid directly to you. Most people find them easier to manage than dealing with traditional insurance claims.

The Bottom Line

Most people choose Plan G because it offers comprehensive coverage with predictable costs. You'll never worry about copays, and you're protected against Part B excess charges. With only the $283 Part B deductible to pay in 2026, your maximum out-of-pocket expense is extremely low.

Plan N is the smart middle ground for healthy individuals who want to save money without taking on significant risk. The copays are manageable, and you can save hundreds of dollars annually.

High-Deductible Plan G paired with CHAS and HIP supplemental coverage is the best value strategy—offering comprehensive protection at the lowest total cost both now and in the long term. With total premiums of just $95-115/month and stable rate increases, you'll save thousands of dollars over time while having superior coverage for serious health events. This is the smartest choice for healthy beneficiaries who want maximum protection at minimum cost.
