Nearly 100 Nassau County retirees allegedly scored duplicate Medicare Part B reimbursements for years, quietly racking up about $1.6 million in extra payments before county auditors fully caught on. A new review by the county comptroller says the improper payouts stretch back decades, and as of June 1 only about $258,000 had been clawed back. County officials say they have frozen disputed checks, are pushing for repayment and are tightening how these benefits are verified going forward.
Audit numbers and who was affected
The Comptroller's review pulled the health-benefits records of about 10,240 living Nassau retirees and flagged 99 suspicious cases, 94 of which were confirmed after follow-up. The report pegs suspected overpayments at $1,623,111.02, with $1,364,938.72 still outstanding and roughly $258,172 recovered as of June 1, 2026, according to a report by the Nassau County Comptroller's Office. County auditors say 39 retirees have repaid or are in the process of repaying, while 55 have not responded to repayment demands.
Why the totals add up
Medicare Part B’s standard monthly premium is $202.90 in 2026, which means that even a twice-yearly county reimbursement can quietly snowball into serious money over time, according to CMS. Nassau typically issues Part B reimbursements in June and December, a schedule the Comptroller’s office says helped enable years of duplicate payments in households where spouses drew the same benefit from different public employers. The county has summarized the review and its recovery efforts on its newsroom page.
How the county discovered the problem and next steps
Staff in the Comptroller’s office first spotted what looked like duplicate payments in October 2025, then launched a deeper review that traced reimbursements back to 2002. According to the audit, the Payroll and Health Benefits Division put holds on payments to affected dependents, sent follow-up letters and will set up repayment plans or installment agreements where needed. The report recommends requiring signed affidavits at retirement, verifying dependents’ eligibility before any payments start and running regular audits so the same problem does not creep back in, per the Comptroller’s full report.
What this means for taxpayers and retirees
The Comptroller’s office says its top priority is recovering taxpayer dollars, and that about $258,172 has been recouped so far, with efforts ongoing to collect the rest, according to the county’s announcement. Officials stress that the fixes on the table are administrative ones - tighter verification at retirement, clearer guidance for households with two public employers and recurring audits - and say retirees who think they were contacted in error should carefully follow the instructions in the county notices.
