A Medicare overpayment demand that a provider fails to pay does not sit indefinitely with the Medicare Administrative Contractor that issued it. Under the Debt Collection Improvement Act of 1996, the Centers for Medicare & Medicaid Services is required to refer eligible delinquent debt to the U.S. Department of the Treasury for cross-servicing and the Treasury Offset Program once the balance reaches 120 days delinquent. Treasury's collection reach extends well beyond what a Medicare contractor can do on its own, and several of the provider's options close before that referral ever happens. What can still be raised after referral, and what has to be resolved before it, are two different questions.
How a Delinquent Overpayment Reaches Treasury
The clock starts with the initial overpayment demand letter. If the balance goes unpaid and the debt is not in an excluded status, the contractor sends an Intent to Refer letter as the final demand, generally 30 to 61 days delinquent, which gives the provider 60 calendar days' notice before the balance moves to Treasury. If the account is still unresolved, CMS is mandated to refer the eligible debt to Treasury by the 120th day of delinquency, a deadline set under the Debt Collection Improvement Act of 1996 and detailed in the CMS Medicare Financial Management Manual.
Cross-Servicing and the Treasury Offset Program
Once a debt is referred, active collection by the Medicare contractor stops, but the debt stays on Medicare's books. Interest continues to accrue, and CMS may continue recoupment against other Medicare payments owed to the provider while Treasury works the referral in parallel. Treasury's Debt Collection Center pursues the balance through demand letters, telephone contact, skip tracing, referral to a private collection agency, and administrative offset under the Treasury Offset Program, which can intercept federal tax refunds, vendor payments, certain federal benefit payments, and eligible state payments. A debt can remain eligible for offset for up to 10 years from the date of determination, and federal employees also face salary offset on the balance.
The Exclusions That Keep a Debt Out of Referral
CMS policy excludes specific categories of debt from referral altogether: debt in bankruptcy, debt under a pending appeal at any level, debt already sent to the Department of Justice, debt owed by a deceased provider or another federal agency, and balances under $25. An approved extended repayment schedule already in effect also keeps the Intent to Refer letter, and the referral that follows it, from going out. None of these protections attach automatically. Filing a timely appeal, negotiating a repayment schedule, or resolving a bankruptcy filing before the referral date is what keeps a debt inside the Medicare appeals system instead of Treasury's collection system. Providers weighing whether to let recoupment run against other Medicare payments in the meantime should also review Immediate Recoupment: Should You Request It before that decision is made for them by the calendar.
Disputing a Debt After It Reaches Treasury
Referral narrows the provider's options, but it does not eliminate them. A provider can still raise a factual dispute about the debt directly with Treasury or its private collection agency. Treasury forwards the dispute to CMS on a Cross-Servicing Dispute Resolution Form, and the Medicare contractor has 30 calendar days to respond and recall the debt if the dispute is valid. That channel reaches errors in the debt itself, such as a payment that was never credited or a balance already resolved, rather than a fresh review of the coverage determination that created the overpayment. The interest that accrued on the debt while it moved through the demand and referral process is typically part of what any dispute has to address.
Once a debt is referred for cross-servicing, active collection by the Medicare contractor stops, but interest and offset do not, and the range of what a provider can still contest narrows considerably.
Why Early Legal Counsel Is Critical
It is critical that providers promptly retain experienced healthcare defense counsel upon receiving an overpayment demand, an Intent to Refer letter, or notice that a debt is being considered for Treasury referral. Early legal intervention can protect the provider's appeal rights before the referral window closes, evaluate whether a repayment schedule or a bankruptcy filing better preserves the provider's position, avoid inadvertent admissions to the contractor or Treasury, and allow counsel to communicate with both on the provider's behalf. Delaying representation can close options that exist only before referral.
