Introduction
Payer contract assignment is an operational reality of healthcare M&A that does not exist in other sectors. Every healthcare services company derives its revenue from contracts with commercial payers (Blue Cross, UnitedHealthcare, Aetna, Cigna, Humana) and government programs (Medicare, Medicaid). When ownership changes, these contracts must be either assigned to the new owner or renegotiated, and the payer has significant leverage in this process. Mishandling payer contract transitions can result in billing interruptions, rate reductions, or loss of network status, any of which can materially impair the value of the acquired business.
Anti-Assignment Clauses
Most commercial payer contracts include anti-assignment provisions that prohibit the provider from transferring (assigning) the contract to a different entity without the payer's prior written consent. These clauses typically define "assignment" broadly enough to capture both direct transfers (asset deals) and changes of control (stock deals where a new owner acquires the legal entity).
- Anti-Assignment Clause
A contractual provision that prohibits a party from transferring its rights or obligations under the contract to a third party without the other party's consent. In healthcare payer contracts, anti-assignment clauses give the payer the right to approve or deny the transfer of the provider's contract to a new owner upon a change of ownership or control. The clause protects the payer's ability to control which providers are in its network and at what reimbursement rates. For acquirers, anti-assignment clauses create transaction risk because the payer can use the consent process to renegotiate terms or refuse to contract with the new owner.
The consent process varies by payer but generally takes 30-90 days. The payer reviews the new owner's credentials, financial stability, quality metrics, and network adequacy needs before granting consent. During this review period, billing continuity depends on the transition structure.
Transition Service Agreements
| Transition Approach | How It Works | Risk Level |
|---|---|---|
| Direct assignment | Payer consents, contract transfers to buyer | Low (if consent is obtained promptly) |
| TSA billing | Seller continues billing under its contract; buyer reimburses | Moderate (compliance risk, duration limits) |
| New contract | Buyer negotiates a new contract directly with payer | High (rate risk, timeline risk, gap risk) |
Transition service agreements (TSAs) are commonly used to maintain billing continuity during the payer consent process. Under a TSA, the seller continues to bill payers under its existing contracts for a defined period (typically 60-180 days) after closing, and the buyer reimburses the seller for the net collections. TSAs provide a bridge but carry compliance risks: the seller is billing for services it no longer provides, which can raise questions under the False Claims Act if not properly structured.
Payer Concentration as Assignment Risk
Medicare and Medicaid Assignment
Government program "assignment" works differently. Medicare and Medicaid do not use commercial-style contracts; instead, providers enroll in the program and bill at published fee schedules. In stock deals, the Medicare provider number remains with the entity and continues to function post-closing (subject to ownership change notification). In asset deals, the buyer must obtain new enrollment, creating the revenue gap risk discussed in the asset-vs-stock article. Government payers do not renegotiate rates during assignment because rates are set administratively, eliminating the rate reset risk that exists with commercial payers.
