Medicare Open Enrollment has officially begun, and millions of seniors now have a limited window to review, compare and update their coverage before 2026 plans take effect. With rising healthcare costs, shifting prescription drug prices, and updated federal rules, this enrollment season is more important than ever. Choosing the right plan now could save seniors hundreds — or even thousands — of dollars next year.
Here is everything you need to know to make the smartest Medicare choice for 2026.
When Open Enrollment Happens — and Why It Matters
Medicare Open Enrollment runs from October 15 through December 7, giving beneficiaries less than two months to review their current plan and make changes. Any option picked during this period will begin on January 1, 2026.
Even if seniors are satisfied with their current plan, they should still double-check coverage because many Medicare Advantage and Part D drug plans are changing premiums, copays, deductibles, and prescription drug lists for 2026.
What’s New for Medicare in 2026
The federal government has approved major changes to improve affordability and transparency. Plans must now clearly show drug prices, provider networks and yearly cost limits. Several expensive medications will receive new negotiated prices in 2026. Mental health and telehealth benefits continue to expand, allowing seniors to access virtual care nationwide.
Medicare Advantage plans will face stricter oversight, reducing the number of denied claims and making it easier for seniors to get pre-approved treatments.
Prescription Drug Updates for 2026
Drug costs will be one of the biggest changes next year. More medications are entering Medicare’s negotiation program, which will reduce out-of-pocket costs for seniors with chronic conditions like diabetes, cancer and heart disease. The insulin price cap remains in effect, continuing to provide major relief for millions.
Part D drug plans may adjust formularies, so seniors must ensure their medications are still covered at the lowest possible cost.

How to Compare Medicare Plans Effectively
Seniors should gather their medication list, preferred doctors and yearly budget before comparing plans. Using Medicare’s Plan Finder tool can help review costs, drug coverage, star ratings and network availability. Beneficiaries should also check whether their doctors remain in-network for 2026, as many Medicare Advantage plans change their provider lists each year.
A licensed Medicare counselor or SHIP program advisor can offer free guidance for seniors who need help reviewing their options.
Medicare Advantage or Original Medicare — Which Is Better for 2026?
Original Medicare remains the most flexible option for doctor choice, while Medicare Advantage plans may offer extra benefits like dental, vision, hearing, fitness membership and prepaid spending cards. However, Advantage plans may come with network limits and prior-authorization rules. Seniors should compare premiums, copays, travel needs and medication costs to decide which option best fits their lifestyle.
Who Should Review Their Plan Immediately
Seniors taking expensive prescription drugs
Beneficiaries with chronic medical conditions
Individuals who saw premium increases in 2025
Anyone with a Medicare Advantage plan that changed networks
Seniors needing telehealth or mental health care
Low-income beneficiaries who may qualify for savings programs
These groups have the most to gain from comparing 2026 options.
Avoiding Medicare Fall Scams
Scam calls increase dramatically during enrollment season. Seniors should never respond to unsolicited calls claiming to “upgrade Medicare benefits” or “add free 2026 coverage.” Medicare will never request banking information, Social Security numbers or payment during open enrollment calls.
