QMB Approved but Still Paying Part B Premium in Texas — Why and How to Fix It

The Approval-to-Check Lag Is Normal

Your parent got the Form H1009 approval letter from HHSC, but the next Social Security check still shows the $202.90 Part B deduction. Before you panic: this is expected. The delay is built into the way three federal and state systems talk to each other.

After HHSC approves QMB, they update an electronic buy-in file and transmit it to CMS. CMS processes the file and instructs Social Security to stop deducting the Part B premium from your parent's monthly benefit. This inter-agency data exchange cycle takes 30 to 60 days under normal processing conditions.

Your Parent Gets the Money Back

Once SSA updates its Master Beneficiary Record, two things happen:

1. Future deductions stop. The next Social Security direct deposit or check reflects the full benefit amount without the Part B subtraction.

2. A retroactive reimbursement arrives. SSA issues a lump-sum payment for every Part B premium deducted between the legal effective date of QMB coverage and the date deductions actually ceased. If QMB coverage was effective November 1 and SSA stopped deducting in February, the reimbursement covers November through January — roughly $609.

SSA issues this reimbursement as a lump-sum payment after it updates the record.

When to Start Asking Questions

If 60 days pass from the Form H1009 approval date and the Part B deduction hasn't stopped:

1. Call HHSC at 2-1-1. Ask the MEPD unit to confirm that the buy-in file was transmitted to CMS and check the transmission date.

2. Call SSA at 1-800-772-1213. Give them the QMB approval date and ask whether the buy-in transaction has been received and when the Part B deduction will be updated on the Master Beneficiary Record.

3. If neither agency can locate the transaction, the buy-in file may have encountered a processing error — mismatched Medicare Health Insurance Claim Numbers (HICNs) or Beneficiary Multiple Identifier (BMI) records cause these. Ask HHSC to retransmit the buy-in data and confirm the correct Medicare identifiers.

The COLA Timing Complication

If your parent was approved for QMB in December or January, the January COLA increase can create a confusing overlap. Social Security increases the monthly check in January — then, a few weeks later, the Part B deduction should disappear as well. When both changes hit close together, the net check amount may not match expectations. Compare the gross benefit (from the annual COLA notice) minus the Part B premium to confirm the calculation.

What About the Months Before Approval?

QMB coverage starts the first day of the month after the HHSC approval — there's no retroactive QMB coverage. So if your parent was paying the Part B premium for six months while the application was processing, those six months aren't reimbursed through QMB.

However, if HHSC determined that your parent also qualified for SLMB during those months, SLMB does allow up to three months of retroactive coverage. Ask whether the caseworker evaluated SLMB retroactivity as part of the QMB determination.
