For many Texans approaching or already in retirement, few things cause more frustration than opening a letter from their Medicare Supplement (Medigap) company and seeing another premium increase. It’s a common experience—one that leaves many wondering why their rates keep climbing and whether they’re paying too much.
Understanding Medicare Supplement costs in Texas in 2026 is essential for making smart, long-term decisions about healthcare coverage. This guide breaks down what Texans are really paying, why premiums rise, and how to keep costs under control without sacrificing quality coverage.
What Medicare Supplement Plans Cost in Texas (2026)
Medicare Supplement (Medigap) plans help cover the out-of-pocket costs that Original Medicare doesn’t—like deductibles, copays, and coinsurance. While the coverage is standardized by the federal government, the premiums vary widely depending on the insurance company, ZIP code, age, and pricing method.
Average Medigap Premiums in 2026
At age 65, the average Medicare Supplement premium in Texas ranges from $149 to $189 per month, depending on the plan and carrier. However, premiums can be as low as $39 or as high as $500+ per month depending on location, health, and plan type.
Here’s a closer look at the most popular options:
- Plan G: The most comprehensive plan available to new enrollees. In 2026, the average cost of Plan G in Texas is around $165 per month at age 65. By age 80, that same plan can exceed $250 per month due to annual rate increases.
- Plan N: A lower-cost alternative with small copays for doctor and ER visits. The average Plan N premium is about $120 per month at age 65, with slower increases over time.
- High Deductible Plan G: Offers the same coverage as Plan G but requires paying a $2,800 deductible (2026) before benefits kick in. Premiums can be as low as $40–$70 per month, making it attractive for healthy retirees who want catastrophic protection at a lower monthly cost.
Why Prices Vary So Much
Even though Medigap plans are standardized—Plan G is the same no matter which company sells it—each insurer sets its own rates. Factors that influence Medicare Supplement pricing in Texas include:
- ZIP code (urban areas like Dallas or Houston often cost more)
- Gender and tobacco use
- Household discounts
- Underwriting (health history if applying outside the open enrollment window)
- Company-specific rate history and claims experience
Why Medicare Supplement Rates Increase
It’s normal for Medicare Supplement premiums to increase over time. Understanding the reasons behind these increases can help set realistic expectations and guide better plan choices.
1. Age-Based Pricing
Most Texas carriers use attained-age pricing, meaning premiums start lower at age 65 and increase as the policyholder gets older. For example, a Plan G that costs $165/month at age 65 might rise to $200 by age 70 and $250+ by age 80.
Other pricing models include:
- Issue-age pricing: Based on the age when the policy is first purchased. Premiums don’t increase due to age but can still rise for other reasons.
- Community-rated pricing: Everyone pays the same rate regardless of age (rare in Texas).
2. Healthcare Inflation
Medical costs rise every year due to higher provider fees, new technology, and increased demand for care. As healthcare inflation continues, Medigap premiums increase to keep up with the cost of claims.
3. Risk Pool Changes
Over time, the group of people insured under a specific plan tends to age and become less healthy. As claims increase, the insurance company must raise rates to maintain financial stability. This is known as risk pool deterioration.
4. Carrier-Specific Rate Adjustments
Each insurance company files rate changes with the Texas Department of Insurance. Some carriers manage their risk better than others, leading to smaller or larger annual increases. Reviewing a company’s rate history can reveal which insurers have been more stable over time.
The “Rate Shock” Problem
Many retirees experience rate shock a few years after enrolling in a Medicare Supplement plan. They initially choose the cheapest option—often from a lesser-known carrier—only to see steep increases later.
While saving $10–$20 per month upfront may seem appealing, the long-term cost difference can be significant. A carrier with a history of aggressive rate hikes can end up costing thousands more over a decade.
The key is to think long-term. A slightly higher premium from a stable, reputable company may provide better value and fewer surprises down the road.
How to Lower or Control Your Premium
While rate increases are inevitable, there are several ways to manage or reduce Medicare Supplement costs in Texas.
1. Compare Carriers Regularly
Because coverage is standardized, comparing rates across multiple insurers can uncover significant savings. A licensed advisor can help identify carriers with competitive pricing and strong rate stability.
2. Review Plans Periodically
Premiums and personal health needs change over time. Reviewing coverage every 1–2 years ensures the plan still fits both budget and medical needs. Switching from Plan G to Plan N, for example, can save $30–$50 per month for those comfortable with small copays.
3. Understand Underwriting Rules
In Texas, switching Medigap plans after the initial enrollment period usually requires medical underwriting. Health conditions can affect eligibility or pricing. However, some carriers offer limited-time “underwriting holidays” or special enrollment opportunities.
4. Consider Household Discounts
Many insurers offer household discounts (typically 5–12%) when two people in the same home have policies with the same company. This can add up to hundreds in annual savings.
5. Explore High Deductible Options
For healthy retirees who rarely visit the doctor, High Deductible Plan G can dramatically lower monthly costs while still providing strong protection against major medical expenses.
Is Medicare Supplement Worth the Cost?
Despite rising premiums, Medicare Supplement plans remain one of the most predictable and flexible ways to manage healthcare costs in retirement.
Key advantages include:
- Freedom to choose any doctor or hospital that accepts Medicare nationwide
- No network restrictions or referrals required
- Predictable out-of-pocket costs, especially with Plan G
- Guaranteed renewable coverage—as long as premiums are paid, coverage cannot be canceled
For many Texans, the peace of mind and financial stability outweigh the monthly cost. While Medicare Advantage plans may offer lower premiums, they often come with network limitations and higher out-of-pocket maximums.
Frequently Asked Questions
1. Why does my Medicare Supplement go up every year?
Premiums increase due to age-based pricing, healthcare inflation, and changes in the insurer’s risk pool. Even if no claims are filed, costs rise as the overall pool of insured individuals ages.
2. Can I switch Medigap plans anytime?
Yes, but in most cases, switching requires medical underwriting unless within a guaranteed issue period. It’s best to compare options before making changes to ensure eligibility and avoid coverage gaps.
3. What is the average cost of Plan G in Texas?
In 2026, the average Plan G premium in Texas is about $165 per month at age 65, though rates vary by ZIP code, gender, and carrier.
4. Is Plan N cheaper than Plan G long term?
Yes, Plan N typically starts around $120 per month and tends to have slower rate increases. However, it includes small copays and doesn’t cover Part B excess charges, which may affect long-term costs depending on healthcare usage.
5. What’s the difference between attained-age and issue-age pricing?
Attained-age pricing increases as the policyholder ages, while issue-age pricing locks in the rate based on the age when the policy is purchased. Most Texas carriers use attained-age pricing.
6. How much does Medigap cost at age 80?
By age 80, many Texans pay $250–$300+ per month for Plan G, depending on the carrier and rate history.
