2. Standard Part D Deductible Increases to $700

The standard maximum deductible for Medicare Part D plans climbs to $700 in 2027. This marks a notable jump from $615 in 2026 and $590 in 2025.

If your plan features this standard deductible, you must pay 100% of your retail drug costs until you satisfy the full $700 amount. Only after meeting this threshold does standard 25% coinsurance activate.

Because many insurers apply deductibles only to higher tiers, you should examine each plan formulary closely. Low-tier generic drugs often bypass the deductible entirely.
