2026 Insulin Cost Protections

$35 Monthly Cap on Insulin

Starting in 2023 and continuing through 2026, Medicare Part D plans must cap insulin costs at $35 per month for each insulin product. This applies to:

Rapid-acting insulin
Long-acting insulin
Intermediate-acting insulin
Premixed insulin

How the Insulin Cap Works

The $35 cap applies to your out-of-pocket costs for covered insulin, including:

During the deductible phase
Throughout the coverage gap (“donut hole”)
In catastrophic coverage phase

Example: If your insulin normally costs $200 per month, you’ll pay only $35 per month with Medicare Part D coverage.

Insulin Coverage Through Part B

Some insulin is covered under Medicare Part B when:

Used with a durable medical equipment insulin pump
Administered via external insulin pump
Furnished by a durable medical equipment supplier

Part B insulin is subject to the Part B deductible and 20% coinsurance, but the $35 cap doesn’t apply to Part B coverage.

Blood Glucose Monitoring Coverage

What’s Covered

Medicare Part B covers blood glucose monitoring supplies for all people with diabetes, including:

Blood glucose monitors (one per year)
Blood glucose test strips
Lancets and lancing devices

Coverage Requirements

To receive coverage, you must:

Get supplies from a Medicare-enrolled supplier
Have a prescription from your doctor
Use Medicare-approved testing supplies

Costs for Testing Supplies

Medicare-approved suppliers: You pay 20% of the Medicare-approved amount after meeting your Part B deductible.

Non-Medicare suppliers: You pay the full cost.

Estimated 2026 costs:

Blood glucose meter: $0-20 (after deductible)
Test strips: $10-15 per month (50 strips)
Lancets: $5-10 per month

Diabetes Medications Coverage

Part D Coverage for Diabetes Drugs

Medicare Part D covers most diabetes medications, including:

Metformin and other oral diabetes medications

Check that your specific diabetes medications are covered
Review the tier placement (affects your cost)

Consider total annual costs, not just monthly premiums

Generic vs Brand Name Savings

Generic diabetes medications typically cost much less than brand names:

Ask your doctor about generic alternatives when available
