Health care is one of the largest and most unpredictable expenses in retirement, with Medicare premiums that include prescription drug coverage one of the biggest costs. In 2026, Medicare will see one of the steepest Part B premium increases in recent years, along with higher deductibles and higher premiums for prescription drug coverage. This means that this year, your guidance as a financial professional is needed more than ever.
Let's look at the Medicare changes for 2026 and how you can help your clients prepare for them.
Part B covers doctor visits, outpatient services and many preventive care benefits. In 2026, both premiums and deductibles will rise sharply.
This year’s increase is the latest in an ongoing trend of higher Part B premiums. From 2020 to 2026, premiums spiked more than 40%.3 According to the 2025 Medicare Trustees Report, Medicare beneficiaries will continue to see increases in Medicare Part B premiums over the next 9 years, making Medicare an essential part of your clients’ financial plans — not just this year, but for many years to come.

Finally, keep in mind that higher-income individuals must pay the income-related monthly adjustment amount (IRMAA), which is a surcharge to their Part B premium. In 2026, a couple who earned between $342,001 and $410,000 in 2024 will pay an additional $527.50 per month for their Part B premium.2

Part D covers prescription drugs through private plans approved by Medicare. Considering that 87% of people ages 65 to 74 use prescription drugs, this is a key cost to watch for retirement planning.4
In 2026, Medicare beneficiaries will see a combination of higher costs and continued caps on prescription drug prices:
As with Part B, Part D costs are on a continuous upward trajectory. From 2023 to 2026, the national base beneficiary premium rose 19%.5 IRMAA also applies to the Part D premium for higher-income beneficiaries. In 2026, a couple who earned between $342,001 and $410,000 in 2024 will pay an additional $60.40 + premium per month for their Part D coverage.2

Medicare Advantage plans vary by insurer and type of plan. For 2026, the Centers for Medicare & Medicaid Services (CMS) report that monthly premiums across Medicare Advantage plans will decrease from $16.40 to $14. However, enrollees may find higher pricing across many of the larger insurers’ plans.
CMS also projects that enrollment in Medicare Advantage will fall for the first time in two decades to 34 million from 35 million in 2025. Historically, half of enrollees leave their Medicare Advantage plans within 5 years. The top reasons for leaving, however, typically involve difficulty accessing care and dissatisfaction with care quality — not cost.
Medicare Advantage open enrollment is January 1 to March 31, 2026. During this time, individuals already enrolled in a Medicare Advantage plan can switch to a different Medicare Advantage plan or return to Original Medicare and enroll in a separate Part D drug plan. However, switching from Medicare Advantage to Original Medicare could result in being denied Medigap coverage (or effectively denied by being priced out), meaning a Medigap insurer can deny coverage or charge higher premiums based on pre-existing conditions and medical underwriting. This would have the effect of making the switch back to Original Medicare not financially feasible.
Rising Medicare costs can have a ripple effect across every part of a client’s retirement plan. Even modest annual increases can translate into meaningful lifestyle adjustments over time. Taken together, Medicare cost increases can:

Your role in guiding clients through Medicare’s complexities is more important than ever. By taking proactive steps, you can help them avoid surprise expenses and make informed choices that preserve their retirement security.
Consider the following strategies:

Medicare is one of the biggest drivers of your clients’ long-term costs during retirement. With premiums and deductibles heading higher in 2026, the stakes are rising for retirees who want to protect their lifestyle and preserve their savings.
Your guidance can make the difference between a post-retirement financial plan that strains under unexpected health care expenses and one that adapts smoothly. By helping clients understand what’s changing, modeling the impact on their budgets and building strategies to manage costs, you show the real value of working with a financial professional who looks at the whole retirement picture.
