As we enter 2026, the landscape of retirement in the Texas Hill Country continues to evolve. While many choose our rolling hills for the world-class wineries in Fredericksburg or the quiet luxury of Boerne, a significant shift is happening beneath the surface: the way high-net-worth (HNW) individuals must manage their healthcare.
For most, Medicare is viewed as a "check-the-box" activity. However, for those with significant assets and income, the choice between Medicare Advantage and Original Medicare (with a Supplement) is no longer just about premiums. It’s about network flexibility, "hidden" taxes like IRMAA, and protecting a legacy from rising out-of-pocket caps.
In this guide, we’ll break down what you need to know about navigating Medicare in 2026 to ensure your health coverage matches your lifestyle.
The "Hidden" Retirement Tax: 2026 IRMAA Brackets
For high-income earners, Medicare isn’t just a benefit; it’s a tiered cost structure. The Income-Related Monthly Adjustment Amount (IRMAA) is essentially a surcharge on your Part B and Part D premiums based on your Modified Adjusted Gross Income (MAGI) from two years prior.
In 2026, the thresholds have shifted. If your 2024 tax return (which Medicare looks at for 2026) showed a MAGI of more than $109,000 for individuals or $218,000 for married couples, you will be paying more than the standard premium.
Why this matters for the Hill Country Lifestyle
Many retirees moving to the Hill Country from Houston or Dallas do so after a major "liquidity event": selling a business, a high-value home, or executing large Roth conversions. If these events aren't timed correctly, you could inadvertently trigger the highest IRMAA tier, where Part B premiums can soar toward $700 per month per person.
Effective strategic wealth protection involves more than just market gains; it involves managing the "tax drag" of programs like Medicare.
Medicare Advantage vs. Medigap: The HNW Dilemma
The debate between Medicare Advantage (Part C) and Medigap (Medicare Supplement) is often framed around cost. But for the affluent retiree, the real debate is about access and friction.
Medicare Advantage in 2026: The "All-in-One" Appeal
Medicare Advantage plans are private insurance alternatives that often bundle dental, vision, and gym memberships (like those at our local Hill Country country clubs). In 2026, many of these plans have an in-network Maximum Out-of-Pocket (MOOP) cap of $9,250.
The Catch: Medicare Advantage plans are typically restricted to regional networks. If you split your time between a ranch in Wimberley and a second home in Colorado, or if you prefer the freedom to visit specialists at MD Anderson in Houston or the Mayo Clinic without a referral, a Medicare Advantage plan might feel restrictive.
Medigap: The "Freedom" Choice
Most of our clients lean toward a Medigap Plan G. While the monthly premium is higher than "zero-premium" Advantage plans, the benefits align better with a luxury lifestyle:
- No Networks: You can see any doctor in the U.S. who accepts Medicare.
- Predictability: After a small annual deductible (roughly $283 in 2026), your out-of-pocket costs for Medicare-approved services are essentially zero.
- No Referrals: You don’t need a "gatekeeper" to see a specialist.
Major 2026 Changes You Should Monitor
The rules for 2026 have introduced several nuances that specifically impact those with higher drug costs or those looking for plan stability.
- The $2,100 Part D Drug Cap: Thanks to the Inflation Reduction Act, the maximum any retiree will pay out-of-pocket for prescription drugs is capped at approximately $2,100 in 2026. This is a massive win for those managing chronic conditions with high-cost specialty medications.
- Network Volatility: Federal funding changes have caused some insurers to scale back their Medicare Advantage offerings. It is estimated that over 1 million seniors will see their specific MA plans discontinued or significantly altered in 2026. For HNW retirees, this means your current doctor may no longer be "in-network" come January.
- Behavioral Health Parity: New rules require Medicare Advantage plans to offer mental health and substance-use-disorder services at the same or better cost-sharing levels as Original Medicare: a vital component of modern retirement wellness.
Healthcare in the Hill Country: A Local Perspective
Living in towns like Boerne or Fredericksburg offers a slower pace of life, but it also means understanding our local medical infrastructure. While we have excellent local facilities like Methodist Hill Country Hospital, many residents still travel into San Antonio or Austin for specialized care.
If you are on a Medicare Advantage plan, you must ensure that the premier specialists in the "Medical Center" of San Antonio are considered in-network. This is why many retirees in communities like Cordillera Ranch or Boot Ranch prefer the flexibility of Medigap: it removes the worry of whether a top-tier surgeon is "in the plan."

How to Prepare for the 2026 Enrollment Period
If you are approaching 65 or looking to switch plans during the Annual Enrollment Period (October 15 – December 7), keep these three steps in mind:
- Review your 2024 MAGI: Determine which IRMAA bracket you will fall into for 2026.
- Audit your travel plans: If you plan on traveling extensively or owning multiple properties, favor the "nationwide access" of Medigap.
- Check your medications: Ensure your 2026 Part D plan covers your specific prescriptions under the new $2,100 cap.
Retirement in the Texas Hill Country should be about the views, the community, and the lifestyle: not the stress of navigating insurance networks. By planning ahead for 2026, you can ensure your healthcare is as seamless as a sunset over the Guadalupe River.
