8.1 Low-Income Subsidy (LIS) / Extra Help

Why the Low-Income Subsidy Matters on the AHIP Exam

The Low-Income Subsidy (LIS), almost universally called Extra Help, is one of the highest-yield topics inside Module 3 (Part D Prescription Drug Plans, 15% of the final). AHIP exam writers use LIS to test two different skills at once: whether you know the federal eligibility math, and whether you understand the agent's limited, compliance-bound role once a beneficiary qualifies. Roughly a quarter of all Part D enrollees receive some form of Extra Help, and dual-eligible beneficiaries are one of the "vulnerable populations" singled out for extra marketing protections in Module 4 — so LIS is a bridge topic that shows up again later in the guide.

Extra Help is federal financial assistance, funded through the Social Security Administration (SSA) and CMS, that reduces or eliminates a beneficiary's Part D premium, annual deductible, and per-prescription copays. It is not a separate insurance plan — it is a subsidy layered on top of whatever stand-alone Prescription Drug Plan (PDP) or Medicare Advantage Prescription Drug (MA-PD) plan the beneficiary is enrolled in.

2026 Eligibility Thresholds

Since Section 11404 of the Inflation Reduction Act (IRA) took effect January 1, 2024, the old two-tier "full" and "partial" subsidy structure is gone. Everyone who qualifies for Extra Help in 2026 receives the full subsidy — there is no more sliding-scale partial benefit. Eligibility is set at 150% of the Federal Poverty Level (FPL), with a resource test:

The resource limit already nets out the $1,500-per-person burial-expense allowance CMS permits, so agents should not add it again when estimating eligibility. Resources counted include bank accounts, stocks, and bonds; a primary residence, vehicle, and personal burial plot are excluded.

What Full Extra Help Covers in 2026

If a beneficiary chooses a plan whose premium is above the regional benchmark, Extra Help only covers up to the benchmark amount — the beneficiary pays the difference. This is a frequent exam trap: Extra Help does not automatically mean a $0 premium on every plan, only on benchmark plans.

"Deemed Eligible" vs. Beneficiaries Who Must Apply

CMS automatically enrolls (or "deems") certain beneficiaries into Extra Help with no application required:

• Full-benefit dual eligibles — enrolled in both Medicare and full Medicaid
• Supplemental Security Income (SSI) recipients who don't also have full Medicaid
• Medicare Savings Program (MSP) enrollees — QMB, SLMB, QI, or QDWI

Everyone else who believes they qualify must actively apply — either through the Social Security Administration (online, by phone, or by mail) or through their state Medicaid agency. This distinction matters for the exam: agents can and should educate a client about the existence of Extra Help and refer them to SSA or Medicaid, but agents do not process LIS applications or make eligibility determinations themselves.

Deemed-eligible status is redetermined every year. A beneficiary who loses Medicaid or MSP eligibility receives a Loss of Deemed Status (LDS) notice (on grey paper) and typically keeps Extra Help through the end of that calendar year, with a chance to requalify. When CMS or a state cannot immediately confirm a beneficiary's status electronically, plans must apply the Best Available Evidence (BAE) policy — temporarily honoring the beneficiary's own proof (an award letter, Medicaid card, etc.) rather than making them pay full price while the systems catch up.

The Continuous Special Enrollment Period

Because their subsidy status can change, LIS/Extra Help beneficiaries (along with dual eligibles and institutionalized enrollees) get a valuable perk the general Medicare population does not: a once-per-month Special Enrollment Period to switch Part D or MA-PD plans. An agent helping a dual-eligible client should never tell them they have to "wait for AEP" — that is both factually wrong and a compliance risk under the non-discrimination marketing rules covered in Chapter 11.

Worked Scenario

Mrs. Alvarez, single, has an annual income of $21,000 and $12,000 in countable resources. She is not on Medicaid. Because her income and resources are both under the 2026 single thresholds ($23,475 / $18,090), she is a strong candidate for Extra Help — but because she is not deemed-eligible (no Medicaid, no SSI, no MSP), she must file an application with SSA or her state Medicaid office. Until that application is approved, she is not entitled to the $0 premium/deductible or capped copays, and the agent's job is limited to explaining the program and pointing her to the correct application channel.

Key Exam Traps

• Confusing Extra Help (federal, drug-cost subsidy) with a Medicare Savings Program (state-administered, covers Part A/B premiums and cost-sharing) — they overlap but are not the same program, and MSP enrollees happen to be automatically deemed eligible for LIS.
• Assuming a $0 premium applies to any plan choice — it only applies up to the regional benchmark.
• Forgetting that the partial-subsidy tier no longer exists as of 2024; any exam answer describing a "partial LIS" percentage-based copay structure is describing the pre-IRA rules and is wrong for 2026.
