Low Income Subsidy (LIS)
LIS (Extra Help) — How It Works at the Pharmacy
LIS, also known as Extra Help, directly affects what you pay when you pick up prescriptions.
━━━━━━━━━━━━━━━━━━━━
What Changes at the Pharmacy When You Have LIS
When LIS is active on your Medicare record:
• Prescription copays are reduced
• Some medications may cost $0
• Deductibles are reduced or eliminated
• Late enrollment penalties for Part D are removed
━━━━━━━━━━━━━━━━━━━━
How the Pharmacy Sees LIS
Pharmacies see LIS through Medicare’s system.
• LIS applies automatically once approved
• You do not need a separate LIS card
━━━━━━━━━━━━━━━━━━━━
Important Pharmacy Notes
LIS only applies to covered drugs on your plan’s formulary.
Copays may differ based on:
• Generic vs brand medications
• Preferred vs non-preferred drugs
If a pharmacy says LIS isn’t active yet:
• Approval may still be processing
• A plan update may be required

How Extra Help (LIS) Connects to D-SNP (Dual / Medicaid) Plans
Extra Help (also called LIS) helps reduce prescription drug costs, but LIS alone does not qualify someone for a D-SNP.
━━━━━━━━━━━━━━━━━━━━
How LIS May Indirectly Connect to D-SNP Eligibility
While LIS does not create D-SNP eligibility by itself, it can be a sign that someone may qualify for additional assistance, including Medicaid-related programs.
• Many individuals who receive LIS meet income guidelines for Medicare Savings Programs (MSPs)
• Medicare Savings Programs may help pay Medicare premiums and cost-sharing
• Some MSP levels include partial Medicaid benefits
• Individuals with Medicare and qualifying Medicaid coverage may be eligible for certain D-SNP plan levels, depending on state rules
━━━━━━━━━━━━━━━━━━━━
Important to Know
• LIS ≠ Medicaid
• LIS alone does not qualify someone for a D-SNP
• Medicare + qualifying Medicaid coverage may make someone eligible for certain D-SNP plan levels
• Eligibility and D-SNP levels vary by state and plan
━━━━━━━━━━━━━━━━━━━━
Why LIS Matters Even Without Full Medicaid
• LIS lowers prescription costs
• LIS provides Special Enrollment Periods
• LIS allows flexibility when transitioning into:
– Medicaid
– Medicare Savings Programs
– D-SNP plans when eligible
━━━━━━━━━━━━━━━━━━━━
Key Takeaway
• LIS = Prescription help
• Medicaid = Medical coverage
• D-SNP = Combined Medicare + Medicaid plan
LIS often acts as a bridge toward higher-level assistance.

Qualifications (Income and Resource Limits Change Each Year)
• Income limits are set annually by Social Security and vary based on household size
• Resource limits are set annually by Social Security and exclude items such as a primary home or vehicle
