Indiana Part B Premium Refund After MSP Approval
Your Parent Got Approved — So Why Is the Premium Still Coming Out?
Your parent's QMB or SLMB approval letter arrived from DFR. The Notice of Action says coverage is active. But the next Social Security deposit still has $202.90 deducted for Part B. This is normal, and it doesn't mean something went wrong with the application.
The gap exists because approval triggers a multi-agency chain that takes 60 to 90 days to complete.
How the Premium Refund Chain Works
Once DFR approves an MSP, the process unfolds across four separate systems:
Step 1: DFR's eligibility system (IEDSS) sends the approval to Indiana's Medicaid Management Information System (MMIS).
Step 2: MMIS submits a monthly state buy-in file to CMS, the federal agency that oversees Medicare.
Step 3: CMS validates the record against Medicare entitlement files and updates SSA's Master Beneficiary Record.
Step 4: SSA finally stops the Part B premium deduction from the monthly Social Security check.
Each of these transfers happens on a monthly batch cycle. If the timing falls between two batch runs, the whole sequence can take an extra month.
When the Refund Arrives
Once SSA processes the buy-in, two things happen. The monthly Part B deduction stops going forward, and SSA issues a lump-sum refund for every premium withheld from the MSP effective date onward. The refund arrives as either a direct deposit or a paper check, depending on how your parent receives Social Security.
A key detail: that refund is excluded from income in the month it's received, and it doesn't count as a resource for nine months after receipt. This matters because a sudden $600–$1,200 deposit could push your parent's bank balance above the $9,950 resource limit if it were counted immediately. The nine-month exclusion prevents that from happening.

QMB vs. SLMB: Different Retroactivity Rules
QMB coverage is strictly prospective. It starts the first day of the month after DFR approves the case. If DFR approves your parent on June 12, QMB benefits begin July 1. There's no back-coverage.
SLMB and QI work differently. They allow up to three months of retroactive coverage before the application month, as long as your parent met the income and resource limits during those months. If your parent applied in June and qualified in March, April, and May, DFR can approve retroactive SLMB for those three months — and SSA will refund the Part B premiums withheld during that entire period.
This retroactive window is one reason to apply as early as possible when you suspect your parent qualifies.
What to Do While Waiting
Keep a copy of the DFR Notice of Action showing the approval date, the MSP category code (MA L for QMB, MA J for SLMB), and the coverage effective date. If the Part B deduction hasn't stopped after 90 days, call the DFR Central Contact Center at 1-800-403-0864 and request a case escalation for overdue processing. You can also call SSA directly at 1-800-772-1213 to verify whether the state buy-in record has reached their system.
