Navigating Rising Medicare Costs: A TIAA Employee’s Guide

“In light of projected Medicare Part B premium increases, TIAA employees should proactively adjust their retirement income projections and consult with a financial advisor to address rising health care expenses.” – Michael Corgiat, a representative of The Retirement Group, a division of Wealth Enhancement.

“In anticipation of significant Medicare Part B premium hikes, TIAA employees would benefit from integrating health care cost projections into their retirement plans and seeking guidance from professional advisors on potential relief strategies.” – Brent Wolf, a representative of The Retirement Group, a division of Wealth Enhancement.

In this article we will discuss:

1. The upcoming Medicare Part B premium increase and its impact on retirement budgets.

2. How Medicare Part B is funded and how COLA adjustments compare to premium hikes.

3. Strategic planning tips to help TIAA retirees manage rising health care costs.

There will soon be a significant shift in Medicare expenses that could affect your retirement budget. According to the 2025 Medicare Trustees Report, the average Part B premium will jump by 11.6%—rising from $185 in 2025 to $206.50 in 2026 ¹ —outpacing most Social Security cost of living adjustments (COLA) over the last decade. TIAA employees should begin factoring this increase into their long-term financial plans.

Benefit Structure for Medicare Part B

Outpatient and preventative care are covered under Part B, including:

• - Cancer screenings, diagnostic procedures, and doctor visits

• - Durable medical equipment and mental health counseling

• - Prescription medications for outpatients and ambulance transportation

• - Skilled nursing services and home health care

In 2025, beneficiaries must pay a $185 monthly premium, a $257 annual deductible, and a 20% co-insurance on most services—important information for any TIAA retiree’s annual budget.

The Funding Mechanisms

There are two primary sources of funding for Medicare Part B:

1. 75% from general U.S. Treasury revenues

2. 25% from premiums paid by beneficiaries

Premium income reached $139.8 billion in 2024, ²  with additional support from brand name drug fees and trust fund interest—details that TIAA retirees may find crucial when reviewing their future health care funding.

Cost of Living Adjustments vs. Premium Increases

In 2026, the “hold harmless” provision that protects most Social Security benefits from Part B hikes may not apply. The anticipated 2.5% Social Security COLA—roughly $50 per month—still falls short of the $21.50 premium increase. Only recipients with monthly benefits under $800 will see any net gain, so TIAA employees relying on Social Security should plan for most of their increase to be offset.

Strategic Planning Tips

To manage rising health care costs, TIAA employees should consider the following proactive steps:

• Forecast Health Care Inflation:  Incorporate rising out-of-pocket costs and premiums into your annual budgeting.

• Compare Plans Online:  Use the official Medicare Plan Finder to evaluate alternatives beyond agent recommendations.

• Manage IRMAA Exposures:  Employ tax-sensitive strategies—such as income smoothing withdrawals—to help limit future surcharges.

• Explore Local Tax Relief:  Research state and municipal programs offering property tax exemptions or rebates for seniors.

• Stress-Test Your Retirement Portfolio:  Model health care inflation scenarios over multiple decades and adjust allocations to safeguard purchasing power.

Extended Consequences

By 2034, annual Part B costs alone could top $3,000–$4,000 if current trends persist—one of the fastest rising expense categories for retirement households. TIAA retirees who plan early can navigate budgetary shocks to help maintain their lifestyle goals.

According to Wealth Enhancement’s Patrick Ray, this premium surge ranks among the steepest retirement cost increases, and prudent investors must factor health care inflation into their retirement forecasts to mitigate unwelcome surprises.
