Overview
A Single Case Agreement (SCA) is a contract negotiated between an out-of-network provider and a health plan for one specific patient's episode of care. The SCA establishes payment terms comparable to in-network reimbursement for that patient without the provider joining the payer's overall network. SCAs enable in-network cost sharing for the patient and reasonable reimbursement for the provider when the patient needs specialty care the network cannot adequately provide.
Common SCA scenarios include: rare-specialty care where the payer's network lacks adequate providers (transplant, complex oncology, specialized pediatrics), geographic access issues where in-network providers are too distant, continuity-of-care situations where a patient has an ongoing relationship with an out-of-network provider and transitioning would be clinically harmful, and emergency care that began out-of-network and continues as the patient stabilizes.
Negotiation typically involves provider RCM or contracting team interaction with the payer's case-management or provider-relations team. Terms include the agreed reimbursement rate (often comparable to the payer's in-network rates for similar services), the services covered, the timeframe, and any prior-authorization requirements that remain.
Patient benefit is significant. Without the SCA, the patient would pay out-of-network cost sharing — typically 40–50% vs 20–30% for in-network services. With the SCA, the patient receives in-network cost sharing despite the provider's out-of-network status. For specialty episodes that can exceed six figures, the patient financial difference is material.
Provider perspective requires judgment. SCAs accept lower reimbursement than typical out-of-network billed charges in exchange for avoiding balance-billing disputes and ensuring the payer's direct payment. Providers who could otherwise collect full charges through balance billing (in states allowing it and absent No Surprises Act protections) face a trade-off between SCA rates and potentially higher balance-billed amounts at higher collection risk.
No Surprises Act interaction has changed SCA dynamics. Where patients are now protected from surprise balance billing, providers have less leverage to pursue higher charges and SCAs have become more commonly offered on favorable-to-payer terms.
Single Case Agreement (SCA) is most operationally disruptive when a payer updates its published policy without a broad provider-facing announcement. The mitigation is pre-emptive monitoring of payer policy bulletins combined with a front-end flag that forces Single Case Agreement (SCA) context into the intake workflow. Pairing Single Case Agreement (SCA) review with out of network and balance billing in the same staleness report keeps the practice ahead of the per-payer churn cycle and compresses the feedback loop between a payer change and the corresponding claim-scrubber update.
From a contracting standpoint, Single Case Agreement (SCA) is one of the payer attributes that should be renegotiated on every contract renewal, not left to default. Practices that ignore Single Case Agreement (SCA) during negotiation leave money on the table via out of network drift and balance billing disputes that could have been prevented at the contract-language level. Reviewers maintain a change log against Single Case Agreement (SCA) so the contracting team has evidence at hand during renewal discussions.
Industry benchmark
SCA rates typically 80–120% of the payer's in-network rates for similar services. Volume: highly variable; large academic medical centers may negotiate 500+ SCAs annually; smaller practices see occasional SCAs.
Worked example
A patient needs complex cardiac surgery from an out-of-network academic medical center. The payer negotiates an SCA with the hospital at rates comparable to its in-network academic-medical-center rates. The patient receives in-network cost sharing (20% coinsurance up to deductible) rather than 50% out-of-network coinsurance. Without the SCA, the patient's out-of-pocket exposure would have been approximately $45,000 vs actual $18,000 under the SCA.
Frequently asked questions — Single Case Agreement (SCA)
Who initiates an SCA?
Either party — patient via their payer case manager, provider through contracting, or payer when case review identifies a need. Patient advocacy often drives the initial inquiry.
Are SCAs only for rare conditions?
No. Common scenarios include specialty-shortage geographies, continuity-of-care situations, and ongoing chronic-care relationships that would be disrupted by network-mandated transitions.
How does the No Surprises Act affect SCAs?
NSA protections reduce provider leverage for balance billing, making SCA rates more favorable to payers. Providers and payers increasingly default to SCA negotiation for out-of-network situations where NSA applies.
