Michigan QMB Approved but Still Paying Part B Premium
Your parent got the DHS-1605 approval letter from MDHHS confirming QMB or SLMB coverage. But the next Social Security deposit still shows the $202.90 Part B premium deducted. The application wasn't denied — the data just hasn't reached Social Security yet.
Why the Delay Happens
MDHHS approves the MSP and enters it into the Bridges system, but the actual premium change requires a chain of data exchanges between three agencies. The MDHHS Third Party Liability unit transmits a buy-in record to CMS through the BENDEX file exchange. CMS updates its records and notifies SSA. SSA then modifies the beneficiary's payroll file to stop deducting the premium.
This loop typically takes 60 to 90 days. During that window, nothing appears wrong from SSA's perspective — they haven't been told to stop, so they keep deducting.
What Happens When It Catches Up
Once SSA processes the state buy-in record, they calculate every Part B premium deducted since the MSP effective date and issue a lump-sum reimbursement. This appears as a larger-than-usual deposit in the monthly Social Security payment or direct deposit.
For QMB, the effective date is the first of the month following the processing month — no retroactivity. For SLMB and ALMB, coverage can be retroactive up to three months before the application month, so the reimbursement can cover several months' worth of premiums.
When to Start Worrying
At 60 days post-approval, the delay is still within normal range. At 90 days, it's time to follow up through two separate channels:
Channel 1: MDHHS Central Buy-In Unit. Call and ask them to confirm that the accretion record was transmitted to CMS through the MMA transaction file. If the file was never sent or was rejected, this is where the problem lives.
Channel 2: Local Social Security Field Office. Bring a copy of the DHS-1605 approval notice and ask them to manually process the buy-in accretion. SSA can update their records with proof of state approval even if the electronic file hasn't arrived.
Don't call just one agency. The delay could be at the MDHHS end (record never transmitted), the CMS end (file processing lag), or the SSA end (manual intervention needed). Contacting both narrows the problem faster than bouncing between them over weeks.

Keep the DHS-1605 Notice
That approval letter is the most important document in this process. It proves the state approved coverage on a specific date, and it's the evidence SSA needs to process a manual buy-in. Make copies before mailing the original anywhere.
Pharmacies also accept the DHS-1605 as proof of MSP status for Extra Help drug copay adjustments under the Best Available Evidence protocol, which matters during the same waiting period when CMS records haven't updated.
