How to Stop Medicare Part B Premium Deduction From Social Security in Alaska
Social Security deducts $202.90 every month from your parent's check for the Medicare Part B premium. On a benefit of $1,400 or $1,600, that deduction takes a meaningful bite. Getting approved for a Medicare Savings Program in Alaska stops that deduction and triggers a refund for the months it shouldn't have been taken.
How the Deduction Stops
When DPA approves your parent for QMB, SLMB, or QI, the agency transmits an electronic "accretion" record to CMS. CMS validates the record and instructs SSA to stop withholding the Part B premium from your parent's monthly Social Security payment.
The state takes over paying the Part B premium directly. Your parent's net Social Security deposit goes up by $202.90 per month — a raise of $2,434.80 annually that comes from eliminating a cost they were already paying.
The Processing Lag
The inter-agency transmission from DPA to CMS to SSA typically takes 30 to 90 days after DPA approval. During this lag, SSA continues deducting the Part B premium from your parent's check even though they've been approved for MSP.
This is normal and expected. Don't panic when the first Social Security check after MSP approval still shows the deduction. The system catches up.
The Retroactive Refund
Once the buy-in accretion processes through SSA's systems, SSA automatically refunds every dollar of Part B premium that was over-withheld. The refund arrives as a lump-sum addition to your parent's regular monthly Social Security direct deposit.
For SLMB and QI, the refund can cover up to three retroactive calendar months before the month of application — on top of the months between approval and when SSA stops the deduction. A beneficiary who applied in July, got approved in August with three months retroactivity (back to April), and didn't see the deduction stop until October could receive a refund covering April through September — six months at $202.90, or $1,217.40.
For QMB, coverage is strictly prospective (starts the first of the month after approval), so the retroactive portion doesn't apply, but the refund for the processing lag months still comes.

How to Verify It Worked
Monitor your parent's Social Security benefit statements. The monthly payment summary shows each deduction line item. When the Part B premium line disappears, the buy-in has taken effect.
If three months pass after DPA approval and the deduction is still there, contact DPA to confirm the accretion record was transmitted. Then call SSA at 1-800-772-1213 to ask whether it was received and whether any action is needed.
Beyond the Part B Premium
If your parent qualifies for QMB specifically, the savings go well beyond the Part B premium. QMB also covers the Part B annual deductible ($283 in 2026), the Part A hospital deductible ($1,736 per benefit period), and all Medicare coinsurance and copayments. These costs don't come out of the Social Security check, but they come out of the bank account — and QMB eliminates them entirely.
