Why government receivables are financed through a double lockbox
Government payers will not accept an assignment of benefits to a factor. A double lockbox structure is how a Medicare or Medicaid receivable is financed anyway.
Direct answer
Medicare and Medicaid claims cannot be assigned to a factoring company because federal law bars reassignment of government payment. A double lockbox structure solves this with 2 accounts: the payer deposits into a lockbox the provider owns, and the factor is repaid by an agreed sweep. Practition Finance refers this structure to funders who build it correctly.
As of October 2026
Why a Medicare receivable cannot be financed like a commercial one
Factoring a commercial insurance claim is simple on paper: the practice sells the invoice, the factor advances against it, and the payer is instructed to remit directly to the factor's lockbox. Federal anti-assignment law treats Medicare and Medicaid differently. The provider agreement that lets a practice bill Medicare in the first place forbids reassigning the right to receive that payment to a third party, which rules out the standard commercial factoring mechanic entirely.
A home health agency, a hospice, or a durable medical equipment supplier with heavy government billing runs into this the first time it tries to factor receivables the same way it would factor a commercial payer invoice. The factor cannot take an assignment, cannot instruct Medicare to redirect payment, and cannot perfect a security interest the way it would on a private claim. Without a workaround, providers with a government-heavy payer mix are effectively locked out of receivables financing altogether.
The double lockbox exists because the underlying economics still work: the receivable is real, it collects at a predictable rate, and the timing gap between billing and remittance is the same problem a commercial-payer provider has. The structure keeps title to the government payment with the provider at every moment, which satisfies the anti-assignment rule, while still giving the factor a controlled, contractual path to be repaid out of the same cash.
How the double lockbox actually works
- 01
The provider opens a lockbox it controls
A bank account, titled to the provider, is established as the deposit account of record with Medicare or Medicaid. The provider updates its payer enrollment so remittances route to this account rather than to its normal operating account. This step is mandatory and cannot be skipped, because it is what keeps the receivable in the provider's name.
- 02
A blocked account or control agreement sits over it
The factor requires a deposit account control agreement or a similar blocked-account arrangement with the bank, giving it the contractual right to sweep funds according to the factoring agreement without ever becoming the account holder or the payee of record. The provider retains ownership; the factor holds a security interest and a sweep right, not a claim to the underlying benefit.
- 03
The factor advances against the same claim
Once the claim is verified and adjudicated or near-adjudicated, the factor advances a percentage of its net collectible value into the provider's operating account, functionally the same advance mechanic used for commercial claims. The difference is entirely in how repayment happens later, not in how the advance is calculated or funded up front.
- 04
The government payer remits into the lockbox
Medicare or Medicaid pays the claim on its normal cycle, depositing directly into the lockbox account titled to the provider, exactly as it would if no factoring relationship existed. Nothing about the payer's process changes, which is precisely the point: the anti-assignment rule is not violated because the payer never sends money anywhere but the provider's own account.
- 05
The second lockbox step sweeps the factor's share
Under the control agreement, the bank sweeps the factor's advance and fee out of the lockbox into the factor's account on a schedule set in the agreement, with the remainder released to the provider. This second movement is the step that gives the structure its name, and it is where the provider's counsel should confirm the sweep language matches the underlying factoring agreement exactly.
- 06
Reconciliation runs claim by claim
Because Medicare and Medicaid remittances arrive in batches covering many claims at once, the factor and provider reconcile each remittance advice against the specific claims that were advanced against, rather than assuming a first-in, first-out match. A provider with high claim volume should expect this reconciliation to be the most operationally intensive part of the relationship.
The comparison that settles it
| Step | Commercial payer | Medicare or Medicaid |
|---|---|---|
| Assignment of the claim | Assigned directly to the factor | Never assigned; barred by federal law |
| Who the payer pays | The factor's lockbox directly | The provider's own titled lockbox |
| How the factor gets paid | Direct remittance from payer | Contractual sweep under a control agreement |
| Legal instrument required | Assignment of benefits | Deposit account control agreement |
| Provider's account ownership | Not applicable | Retained by the provider at every step |
What a provider with government receivables should do
A home health agency, hospice, or DME supplier evaluating receivables financing should ask any prospective factor directly how it handles Medicare and Medicaid claims before signing anything, since not every factor is set up to run a compliant double lockbox. The answer should name the control agreement, the bank, and the sweep mechanics specifically, not a general assurance that government claims are handled.
Providers with a payer mix split between commercial and government claims often run both mechanics side by side: standard assignment-based factoring on the commercial book and a double lockbox on the government book, reconciled separately. Practition Finance refers medical receivables factoring and AR line requests by state to funders equipped to structure both legs correctly for a provider's actual payer mix.
Do not sign a factoring agreement that asks the provider to assign Medicare or Medicaid benefits directly; that assignment is unenforceable and signals the factor has not built the compliant structure

What owners ask about this
01Why can Medicare receivables not be assigned to a factor?
Federal law governing the Medicare program bars reassignment of the right to receive payment to anyone other than the enrolled provider, with narrow exceptions unrelated to commercial financing. This anti-assignment rule exists to prevent third parties from stepping into a provider's billing relationship with the government. A double lockbox works around it without violating it, because the payer still pays the provider directly.
02Does Medicaid follow the same rule as Medicare?
Medicaid programs generally follow the same anti-assignment posture, though the details are set at the state level, and providers should confirm the specific state Medicaid program's rules with their factor and counsel. The double lockbox mechanic is built to satisfy this class of restriction generally, which is why it is used across both Medicare and Medicaid receivables rather than a different structure for each.
03Is a double lockbox more expensive than standard factoring?
It can carry additional bank fees for the control agreement and lockbox maintenance, and the reconciliation work is more involved, which some factors reflect in pricing. The core discount fee and advance rate are typically set the same way as a commercial claim, based on net collectible value, so the structural cost sits alongside the standard fee rather than replacing it.
04Which providers actually need this structure?
Home health agencies, hospices, skilled nursing operators, and durable medical equipment suppliers with a material share of billing to Medicare or Medicaid are the providers who encounter this. A practice billing mostly commercial insurance with an occasional government claim rarely needs the full double lockbox and can often factor the commercial book alone.
05What does Practition Finance do for a provider with government receivables?
Practition Finance is an independent business financing referral service. It identifies whether a provider's payer mix requires a double lockbox, a standard assignment structure, or both, and, by state, refers the request to funding partners who build the compliant structure and present terms directly. The provider is not charged for that referral.
