Every year, Medicare updates bring new costs, benefits, and opportunities for enrollees. For 2026, there are several important changes that will affect premiums, drug costs, and plan options here in San Diego County. Here’s a clear breakdown of what you need to know before the Annual Enrollment Period (October 15 to December 7, 2025).
Medicare Part B Premiums and Deductible Are Rising
The standard Medicare Part B premium is expected to increase to $206.50 per month in 2026 up from $185.00 in 2025. That’s roughly an 11.6% increase from the 2025 premium. Additionally, the Part B annual deductible will increase from $257 to $288. These changes affect everyone on Original Medicare (Parts A & B) and those with Medicare Supplement plans.
Part D Prescription Drug Costs Are Changing
Several adjustments are coming to Medicare Part D:
-
The out-of-pocket cap for prescription drugs is increasing to $2,100 in 2026 (up from $2,000 in 2025).
-
If your plan has a deductible, the maximum allowed will rise to $615 for the year.
-
The $35/month cap on insulin remains in place, and plans cannot apply a deductible to covered insulin products.
- Members who qualify for the Low-Income-Subsidy (LIS) will pay up to $5.10 for generic or preferred drugs and up to $12.65 for brand-name drugs during the initial coverage phase.
- Members enrolled in the Medicare Prescription Payment Plan will be automatically re-enrolled for 2026, provided they remain on the same plan.
These changes are part of the continued rollout of the Inflation Reduction Act, which aims to lower drug costs and make spending more predictable for beneficiaries.
Big Changes with UCSD Medicare Advantage Options in San Diego
As we approach 2026, UC San Diego Medical has announced significant changes regarding the Medicare Advantage plans they will accept. Up until now, UCSD welcomed a handful of Medicare Advantage plans, including HMO options, allowing flexibility for a broad group of Medicare beneficiaries. However, starting in 2026, UCSD Medical will only accept a select number of Medicare Advantage plans while still accepting all Medicare Supplement plans (Medigap). This change will affect many patients who rely on UCSD Medical as their primary healthcare provider. Members on Humana, SCAN, UnitedHealthcare®, and Blue Shield plans have all received letters from their carriers informing them they will no longer have access to UCSD in 2026.
