Wyoming Social Security and Medicare Savings Program
Social Security Is Both the Problem and the Path
For most Wyoming seniors on a Medicare Savings Program, Social Security is their only income. It's the number WDH uses to determine eligibility, it's where the Part B premium gets deducted every month, and it's where the savings show up once the program kicks in.
Understanding how Social Security and MSP interact—from the initial eligibility calculation to the Part B deduction mechanics—eliminates most of the confusion families face during the application.
How Social Security Counts Toward MSP Eligibility
WDH counts gross Social Security benefits as unearned income, then applies the $20 general disregard. The gross amount is the benefit before Medicare Part B premiums, income tax withholding, or any other deductions—not the net deposit in the bank account.
The Social Security Administration reports gross benefits to WDH electronically through the BENDEX data exchange. The number on the SSA-1099 (Box 3, Net Benefits) doesn't match what WDH uses—Box 3 already subtracts the Part B premium. Use the gross benefit amount from the Social Security award letter or benefit verification letter, available at ssa.gov.
Example: A Wyoming senior receives $1,400 gross Social Security. After the $20 disregard, countable income is $1,380. That's above the QMB income standard ($1,330) but below SLMB ($1,596). They qualify for SLMB, which pays the Part B premium and triggers automatic Extra Help for prescriptions.
The Part B Deduction Cycle
Here's what happens to the Part B premium through the MSP timeline:
Before MSP: SSA withholds the standard Part B premium ($202.90 per month in 2026) directly from the Social Security check. The beneficiary never sees this money—it's deducted before the deposit.
After MSP approval: WDH transmits a buy-in transaction to SSA through BENDEX. SSA processes the buy-in and stops withholding the Part B premium. The monthly Social Security deposit increases by the premium amount.
The lag: This processing takes 60 to 90 days. During the gap, the premium keeps coming out even though the state has approved coverage.
Retroactive refund: For SLMB and QI, coverage can be retroactive to the application month plus up to three prior months. SSA refunds all Part B premiums deducted during the retroactive period as a lump-sum payment. For QMB, coverage starts prospectively—no retroactive refund of premiums, but all future premiums and cost-sharing are covered.

The Social Security Fairness Act Impact
The Social Security Fairness Act (signed January 5, 2025) repealed the Government Pension Offset (GPO) and Windfall Elimination Provision (WEP). This matters for MSP eligibility in two ways:
Ongoing benefit increases: Beneficiaries whose Social Security was previously reduced by WEP or GPO now receive higher monthly checks. If the increase pushes their income above MSP thresholds, they may lose eligibility at their next renewal. WDH re-evaluates income against current FPL limits during annual redeterminations.
Retroactive lump-sum payments: SSA issued backpay to affected beneficiaries going back to January 2024. Under Medicaid accounting rules, these lump-sum payments are excluded from countable resources for 9 months after receipt. The money won't disqualify your parent from MSP during that window—but it must be kept in an identifiable account and tracked. After 9 months, any remaining lump-sum balance becomes a countable resource.
SSI Recipients Get MSP Automatically
Wyoming is a Section 1634 state, meaning individuals approved for SSI through the Social Security Administration are automatically enrolled in Wyoming Medicaid—including Medicare Savings Programs—without filing a separate state application. SSA transmits the eligibility data through the State Data Exchange (SDX), and WDH activates coverage.
If your parent receives SSI and is also on Medicare, they should already have MSP benefits. Verify by calling the WDH Customer Service Center at 1-855-294-2127 with their Medicaid case number.
