2026 Medicare Changes: What You Need to Know

Navigating Medicare can feel like a moving target, but 2026 brings critical federal updates to healthcare costs, benefit limits, and coverage rules. Most notably, out-of-pocket costs for covered prescription drugs are capped at $2,100 under Part D, standard premiums and deductibles across the program have recalibrated to economic trends, and federally negotiated drug prices are officially taking effect on select high-cost medications. Beyond this year's updates, federal regulators are already laying the groundwork for 2027 by expanding the drug price negotiation list and tightening Medicare Advantage guidelines. At SelectQuote, we make sense of these evolving regulations so you can confidently secure the best coverage for your budget.

What is changing with Medicare Part D in 2026?

The Inflation Reduction Act continues to impact Medicare prescription drug coverage costs, resulting in lower out-of-pocket limits and restructured payment options for 2026:

• $2,100 Out-of-Pocket Cap: For 2026, annual out-of-pocket spending on covered Part D medications is capped at $2,100. Once you reach this threshold, you enter the catastrophic coverage phase and pay $0 for your covered prescriptions for the rest of the calendar year.

• Maximum Deductible Adjustment: The maximum allowable Part D deductible increased to $615 (up from $590 in 2025). Note that depending on your specific plan, your actual deductible may be lower.

• Medicare Prescription Payment Plan: You can opt into this payment model to spread your out-of-pocket prescription costs into manageable monthly installments throughout the year rather than paying full price up front at the pharmacy counter.

How are Medicare Advantage (Part C) plans changing?

Private insurance companies continuously update Medicare Advantage plan details to adapt to new federal requirements and market shifts. For 2026, many carriers are adjusting their provider networks, restructuring copays, and modifying additional benefits (such as dental, vision, hearing, and wellness allowances).

Key 2026 Medicare Advantage plan updates include:

• Lower Maximum Out-of-Pocket Limit (MOOP): The maximum allowable in-network out-of-pocket spending limit for Medicare Advantage plans decreased slightly to $9,250 for 2026 (down from $9,350). Once you reach your plan's specific MOOP limit, the plan pays 100% of the cost for covered in-network medical services for the remainder of the year.

• Lower Projected Drug Plan Premiums: The average monthly premium for Medicare Advantage plans that include Part D prescription drug coverage (MAPDs), after applying plan rebates, is projected to drop to $11.50 in 2026.

When can I make changes to my Medicare coverage?

If your plan's upcoming changes no longer fit your needs or budget, you can adjust your coverage during specific enrollment windows:

• Annual Enrollment Period (AEP): October 15 to December 7: The primary window for any Medicare beneficiary to make adjustments to their coverage. During this period, you can switch from Original Medicare to a Medicare Advantage plan, return to Original Medicare from Medicare Advantage, or change your current Medicare Advantage or Part D prescription drug plan. Adjustments made during AEP take effect on January 1.

• Medicare Advantage Open Enrollment Period (OEP): January 1 to March 31: An enrollment window reserved exclusively for individuals who are already enrolled in a Medicare Advantage plan as of January 1. During this period, you can switch to a different Medicare Advantage plan or return to Original Medicare. You cannot use this window to transition from Original Medicare to a Medicare Advantage plan for the first time.

• Special Enrollment Period (SEP): Occurs Upon Qualifying Life Events: Certain qualifying life events—such as moving outside your plan's service area, losing employer-sponsored coverage, or qualifying for Extra Help—allow you to make plan changes outside the standard enrollment periods.
