Medicare Part A Buy-In in Oregon: How QMB Covers the Premium Without 40 Quarters
Most people get Medicare Part A for free because they — or their spouse — worked 40 quarters (10 years) and paid Medicare taxes. But for seniors who did not reach that threshold, Part A carries a monthly premium of up to $505 in 2026. That is a devastating bill for anyone on a low fixed income. Oregon offers a way around it through the QMB program and the state's Part A buy-in designation.
What "Buy-In State" Means
Oregon is classified as a Part A Buy-In State under the Social Security Administration's Program Operations Manual System (POMS HI 00801.140). This designation gives Oregon a critical procedural advantage for low-income residents who lack premium-free Part A.
In a buy-in state, an individual who qualifies for QMB can enroll in Part A at any time of year — not just during the General Enrollment Period (January through March). And the late enrollment penalty that normally applies when someone delays Part A enrollment does not apply when enrollment occurs through state buy-in.
This is a significant difference from "Group Payer" states, where QMB applicants without Part A must wait for the annual enrollment window and may face penalties.
The Four-Step Process
Getting Part A through Oregon's QMB buy-in involves coordination between Social Security and ODHS. The steps need to happen in the right order.
Step 1: File a Conditional Part A Application at SSA
Your parent visits or contacts the Social Security Administration and files an application for Medicare Part A as a conditional enrollment. They tell SSA that Part A enrollment is conditional upon Oregon approving QMB status. If your parent also needs Part B, they apply for both at the same time.
SSA processes the conditional application but holds billing — your parent will not be charged the Part A premium while the QMB application is pending.
Step 2: Get Proof From SSA
SSA provides an official application receipt or screen printout confirming the conditional Part A enrollment. This document is essential for the next step.
Step 3: Apply for QMB at ODHS
Your parent submits a QMB-BAS application to ODHS through the ONE Oregon portal (one.oregon.gov), by phone (800-699-9075), or at a local APD or AAA office. Attach the SSA conditional Part A enrollment proof to the application.
For QMB eligibility, countable income must be within 100% of the Federal Poverty Level: $1,350/month single or $1,824/month couple (after the $20 disregard). Oregon has no asset test for QMB.
Step 4: QMB Approval Triggers the Buy-In
When ODHS approves QMB-BAS, it transmits a buy-in transaction code to CMS. CMS updates SSA, activating Part A coverage and billing both the Part A and Part B premiums directly to the State of Oregon. Your parent pays nothing for either premium.
What Happens If QMB Is Denied
If ODHS denies the QMB application, SSA voids the conditional Part A enrollment automatically. Your parent is not billed for Part A premiums during the period the application was pending. There is no financial risk to applying.
If the denial was based on an income calculation error — the most common reason — your parent can appeal through an administrative hearing (see our post on appealing MSP denials in Oregon).

The Financial Impact
Without the buy-in, a low-income senior without premium-free Part A faces:
- Part A premium: up to $505/month ($6,060/year)
- Part B premium: $202.90/month ($2,434.80/year)
- Part A and Part B deductibles and copays
- Part D prescription costs
With QMB through Oregon's buy-in:
- Part A premium: $0
- Part B premium: $0
- All Medicare deductibles and copays: covered by QMB
- Part D copays: for MSP-only recipients, capped at $5.10/$12.65 through automatic Extra Help; full dual enrollees may pay less ($1.60/$4.90, or $0 for institutionalized or HCBS waiver recipients)
The difference can exceed $10,000 per year in total healthcare costs.
Who This Applies To
The Part A buy-in is relevant for seniors who:
- Immigrated to the United States later in life and did not accumulate 40 quarters of covered employment
- Worked primarily in jobs not covered by Social Security (some state and local government positions, certain religious organizations)
- Were homemakers whose spouse did not work enough quarters, or whose spouse's record does not qualify them for premium-free Part A on a spousal claim
- Lost premium-free Part A status under specific circumstances and cannot afford the premium to re-enroll
If your parent falls into any of these categories and their income is below $1,350/month (single) or $1,824/month (couple), the QMB buy-in route eliminates the Part A premium entirely.
