Medicare Diabetes Coverage: What's Covered in 2025

# Medicare Diabetes Coverage: What's Covered in 2025

Diabetes affects millions of Medicare beneficiaries, and understanding your coverage for diabetes care, supplies, and medications is essential for managing your health and costs. Recent changes, including the $35 monthly insulin cap, have significantly improved diabetes coverage for Medicare enrollees.

The $35 Insulin Cap

Starting in 2025, all Medicare beneficiaries pay no more than $35 per month for each covered insulin product, regardless of which Medicare plan they have. This applies to:

• Part D prescription coverage - insulin purchased at pharmacies
• Part B durable medical equipment - insulin used with pumps
• Medicare Advantage plans - must honor the same cap

This cap represents significant savings for many beneficiaries who previously paid hundreds of dollars monthly for insulin.

Diabetes Supplies Under Part B

Medicare Part B covers diabetes supplies used with insulin pumps and certain testing equipment as durable medical equipment (DME):

Covered Under Part B:

• Blood glucose monitors
• Blood glucose test strips
• Lancets and lancet devices
• Glucose control solutions
• Continuous glucose monitors (CGMs)
• Insulin pumps and supplies

Cost: You pay 20% of the Medicare-approved amount after meeting the Part B deductible. Using Medicare-enrolled suppliers is essential—otherwise, Medicare won't cover the items.

Continuous Glucose Monitors (CGMs)

Medicare covers CGMs for beneficiaries who:

• Have diabetes treated with insulin
• Require frequent glucose monitoring
• Meet specific medical criteria

Covered CGM brands include Dexcom, FreeStyle Libre, and Medtronic systems. Your doctor must document medical necessity for coverage.

Diabetes Medications Under Part D

Beyond insulin, Part D covers other diabetes medications:

• Metformin and other oral medications
• GLP-1 receptor agonists (Ozempic, Trulicity, etc.)
• SGLT2 inhibitors (Jardiance, Farxiga)
• Combination medications

Important: Starting 2025, the new $2,000 annual cap on Part D out-of-pocket costs benefits many beneficiaries with diabetes who take multiple medications.

Preventive Care Coverage

Medicare covers diabetes prevention and management:

Diabetes Screening

• Free for those at risk (high blood pressure, obesity, family history)
• Covered twice yearly for diagnosed pre-diabetes

Diabetes Self-Management Training (DSMT)

• Learn to manage your diabetes
• Nutrition counseling
• Understanding medications
• Monitoring techniques

Medical Nutrition Therapy

Diabetes Shoes and Custom Inserts

Medicare Part B covers therapeutic shoes for beneficiaries with diabetes-related foot conditions:

• One pair of depth shoes and three pairs of inserts annually
• OR one pair of custom-molded shoes
• Must be prescribed by your treating physician
• Fitted by a podiatrist, orthotist, or qualified provider
