Medicare Savings Programs, QMB, SLMB, and QI

There are three tiers, separated mainly by income, and they pay for progressively less as the income limit rises. The Part B premium is the common thread: all three help with it. The differences are at the top, where the most generous tier reaches into the rest of your Medicare cost-sharing.

• QMB (Qualified Medicare Beneficiary): the top tier. It can cover your Part B premium and also your Part A and Part B deductibles, coinsurance, and copays.
• SLMB (Specified Low-Income Medicare Beneficiary): pays the Part B premium only, with a higher income limit than QMB.
• QI (Qualifying Individual): also pays the Part B premium, with the highest income limit of the three. It is funded annually and granted first-come, so applying early in the year matters, and you cannot have QI if you also qualify for Medicaid.

There is a fourth, narrower program (QDWI) for certain people working with disabilities who have lost premium-free Part A; it is uncommon enough that most readers will only need the three above.

The single most common reason people skip these programs is a guess about their own income that turns out to be wrong. The limits are set as a percentage of the federal poverty level and they move every year, and the QI tier in particular reaches well up into modest fixed incomes. Some income is also not counted the way people expect, and a portion of earned income is disregarded in the math. The practical move is to check the current year's figures for your state rather than rely on a number you heard once.

These programs historically counted assets as well as income, and the asset rules scared off a lot of people who would have qualified on income alone. That has been shifting: a number of states have raised or eliminated the asset limit for the Medicare Savings Programs. Even where an asset test remains, your home and your car are typically not counted, which surprises people who assume any savings disqualify them. Because this varies most by state, your state's current rule is the only one that matters for you.

This is a real federal right that goes routinely unused. If you have QMB, Medicare providers are prohibited from billing you for Medicare cost-sharing, the deductibles, coinsurance, and copays QMB is meant to absorb. It is called the balance-billing protection.

In practice, billing systems often do not know a patient has QMB, so bills go out anyway and people pay them, assuming they owe the money. They usually do not. If you have QMB and get a bill for a Medicare deductible or coinsurance, you can tell the provider you are a QMB beneficiary, ask them to stop billing and refund what you paid, and contact Medicare if it continues.

Here is the part that makes the paperwork worth it: enrolling in any of the three Medicare Savings Programs automatically makes you eligible for Extra Help, the Part D low-income subsidy that lowers prescription costs. So a single application to your state can unlock both premium help and drug help at once. That linkage is the strongest argument for checking even if you are unsure, because the downside is a short application and the upside is two benefits.

Because the states run these, you apply through your state Medicaid agency, not Social Security (Extra Help is the one that goes through Social Security). The application asks about income and, depending on your state, assets. A SHIP counselor or a licensed agent can walk you through it at no cost.

Plan for one thing: these are not always permanent. The program asks you to confirm you still qualify on a periodic basis, a redetermination, and people sometimes lose coverage simply by missing a renewal notice rather than by becoming ineligible. Keep your address current with the agency and open anything they send.
