Wisconsin Part A Buy-In: How QMB Covers Your Part A Premium
Why Part A Buy-In Matters
Most people get premium-free Medicare Part A because they or a spouse accumulated 40 quarters of covered employment. But if neither your parent nor a qualifying spouse has 40 quarters — common among immigrants, homemakers, or people who spent careers in non-covered public employment — Part A comes with a monthly premium. In 2026, that premium runs up to $505 per month.
Without the buy-in route, your parent may need to wait for the General Enrollment Period (January 1 through March 31) to sign up for Part A and could face a late enrollment penalty on top of the premium.
Wisconsin's Part A buy-in status eliminates both problems.
What Buy-In State Status Means
Wisconsin is classified as a Part A buy-in state under Section 1818(g) of the Social Security Act. This gives QMB-eligible residents two critical advantages:
Year-round enrollment. A person who already has Part B and is not eligible for premium-free Part A can apply for Part A at the Social Security office any time — not just during the General Enrollment Period. The enrollment is filed as "conditional" under POMS HI 00801.140, meaning it only takes effect if QMB is approved.
No late enrollment penalty. Because the enrollment is conditional on state buy-in, the normal Part A late enrollment penalties don't apply.
The Step-by-Step Process
Visit an SSA field office. Your parent (or their authorized representative) files an application for Part A, explicitly requesting conditional enrollment under POMS HI 00801.140. They sign a statement confirming that enrollment is conditional on QMB approval by the state.
File the MSP application. Immediately submit the QMB application to the county Income Maintenance consortium through ACCESS or paper Form F-10182. Don't wait — the two applications should be in motion at the same time.
Consortium approves QMB. Once the Income Maintenance worker verifies countable monthly income (at or below the $1,350 single limit after applicable disregards) and assets (at or below $9,950), they approve QMB eligibility.
State buy-in takes effect. Wisconsin's automated system transmits the accretion record to CMS. The Part A enrollment activates, and Wisconsin pays the Part A premium directly to CMS. Your parent never receives a premium bill.

If SSA Refuses the Conditional Application
Some SSA field office representatives don't know about Part A buy-in or conditional enrollment. They may tell your parent they have to wait for the General Enrollment Period. If this happens:
- Request immediate supervisory escalation
- Cite POMS HI 00801.140, Section C — the specific instruction covering Part A buy-in states
- Specify that Wisconsin is a buy-in state and the applicant is seeking conditional enrollment contingent on QMB
This is documented federal procedure, not a workaround. The SSA field office manual covers it.
QMB Pays Both Premiums
Once everything is processed, QMB pays both the Part A premium (up to $505/month) and the Part B premium ($202.90/month). That's potentially $707.90 per month in premium coverage, plus QMB's elimination of all deductibles, coinsurance, and copayments.
Who This Matters For Most
The Part A buy-in route is particularly relevant for immigrants who arrived in the United States later in life and haven't accumulated 40 quarters of covered employment. It's also important for people who spent their careers in government positions that didn't pay into Social Security — though the Social Security Fairness Act repealed the Windfall Elimination Provision and Government Pension Offset for benefits payable beginning January 2024, which may have changed their overall benefit picture.
Without the buy-in pathway, these individuals face the full Part A premium ($505/month in 2026), restricted enrollment windows, and late penalties. With QMB in a buy-in state, all of that is eliminated.
