Getting a Single Case Agreement With Your Insurer

What a single case agreement is

A single case agreement, sometimes called an SCA, is a one-time contract an insurer makes with an out-of-network provider so that a specific patient can be treated at in-network cost-sharing for a specific course of care. It does not add the program to the plan's network. It carves out one exception for one person, setting an agreed rate and applying your ordinary in-network deductible and coinsurance rather than the far larger out-of-network exposure.

The reason this matters is money. Out-of-network, a program sets its own charge with no negotiated ceiling and your plan may pay little or nothing, leaving you exposed to balance billing across a long stay. A single case agreement converts that into predictable in-network cost-sharing for the episode it covers. An SCA is a one-off bridge to in-network cost for out-of-network care — not a permanent network change, and not automatic. It is negotiated before treatment, and it exists precisely for the situation where the right care and your network do not line up.

When an insurer will actually consider one

Insurers grant single case agreements in a limited set of circumstances, and knowing them tells you whether you have a case. The most common is a network adequacy gap exception — the plan has no in-network provider who can deliver the medically necessary care within a reasonable distance or timeframe. If the specialized substance-use care you need genuinely is not available in-network, that gap is the core of the argument.

Continuity of care is another: if you are already established with an out-of-network provider mid-treatment, or a program that just went out-of-network, plans may agree to an out-of-network exception to avoid disrupting care. Parity strengthens both arguments. The mental health parity law generally requires that a plan covering substance-use benefits not impose more restrictive financial requirements or treatment limits on that care than it applies to comparable medical and surgical care 1Ref 1Centers for Medicare & Medicaid Services (2024).Mental Health Parity and Addiction Equity Act (MHPAEA).That MHPAEA generally requires plans covering substance-use benefits not to impose more restrictive financial requirements or treatment limits than for comparable medical/surgical care, including how out-of-network access is handled — the leverage in requesting or appealing a single case agreement.. If a plan would arrange out-of-network access for a comparable medical need but resists it for addiction treatment, the MHPAEA parity requirements are the standard to invoke. The strongest SCA case is a genuine network gap for medically necessary care — parity is the lever that keeps the plan honest about it.

How to request one, step by step

A single case agreement is requested before treatment, and it usually runs through the program's billing or utilization staff, though you can and should stay involved. The request is a negotiation, so the more organized the documentation, the better the odds. The sequence is fairly consistent across plans.

• Confirm there is no adequate in-network option and document your search — which in-network programs you contacted and why they could not meet the need.
• Have the out-of-network program's clinician document medical necessity — the assessment, the level of care required, and why the program meets it.
• Ask the program whether it will initiate the SCA with your insurer; many do this routinely, and experienced billing staff know the process.
• Contact your plan's behavioral-health line to open the request and ask exactly what it needs to consider one.
• Get any agreement in writing before treatment begins — the agreed rate, the covered services and dates, and your cost-sharing.

You do not have to run this alone — a legitimate program's billing team handles single case agreements regularly and can lead the negotiation. What you contribute is the record that no in-network option fit and the persistence to get the terms in writing before care starts.

Building the medical-necessity case

The heart of a single case agreement request is medical necessity: a documented clinical argument that this specific out-of-network program meets a need your network cannot. That case is built from a proper assessment — the diagnosis, the recommended level of care, and the specific reason in-network options are inadequate, whether that is a specialized program, a needed medication, or a lack of any in-network bed within reach.

The program's legitimacy is part of the argument, because an insurer is more likely to agree with an accredited provider than an unvetted one. CARF is an independent accreditor of behavioral-health and substance-use programs, using peer surveyors against published standards 2Ref 2CARF International (2024).Behavioral Health Accreditation.That CARF is an independent accreditor of behavioral-health and substance-use programs, using peer surveyors against published standards, with a top decision of a three-year accreditation., and the Joint Commission accredits substance-use and behavioral-health facilities through comprehensive on-site reviews at least every three years against national safety and quality standards 3Ref 3The Joint Commission (2024).Behavioral Health Care and Human Services Accreditation Program.That The Joint Commission accredits substance-use and behavioral-health facilities and conducts comprehensive on-site reviews at least every three years against national safety and quality standards..

A well-accredited, clearly licensed program strengthens both your care and your single case agreement request — an insurer weighs credibility. Documenting these alongside the clinical case makes the request harder to wave away.

Try in-network first — and verify what you find

Before pursuing a single case agreement, it is worth a genuine search for in-network care, both because it is usually cheaper and faster and because an insurer will ask whether you tried. Start from a neutral government source: FindTreatment.gov is the federal government's free, confidential, and anonymous locator of state-licensed treatment facilities for mental-health and substance-use disorders 5Ref 5Substance Abuse and Mental Health Services Administration (2024).FindTreatment.gov.That FindTreatment.gov is the federal government's free, confidential, anonymous locator of state-licensed treatment facilities for mental and substance use disorders, used to search for in-network options first.. Filter for programs in your plan and confirm each is truly in-network for your specific plan, not merely "accepts your insurer."

This search does double duty. If it turns up a suitable in-network program, you may not need an SCA at all — a better outcome than negotiating an exception. If it turns up nothing adequate, that documented absence becomes the network adequacy gap your request rests on. The comparison between in-network and out-of-network residential care is not only about cost; it is the evidence base for whether an exception is justified. Either way, verify quality independently — license and accreditation — rather than treating an out-of-network program's price or marketing as a mark of quality 2Ref 2CARF International (2024).Behavioral Health Accreditation.That CARF is an independent accreditor of behavioral-health and substance-use programs, using peer surveyors against published standards, with a top decision of a three-year accreditation.3Ref 3The Joint Commission (2024).Behavioral Health Care and Human Services Accreditation Program.That The Joint Commission accredits substance-use and behavioral-health facilities and conducts comprehensive on-site reviews at least every three years against national safety and quality standards..

If the request is denied, and a caution

A denied single case agreement is not the end of the road. You can appeal, and parity is often the strongest ground: if the plan's handling of out-of-network access for addiction treatment looks harsher than for a comparable medical need, that disparity is what a parity-based appeal targets 1Ref 1Centers for Medicare & Medicaid Services (2024).Mental Health Parity and Addiction Equity Act (MHPAEA).That MHPAEA generally requires plans covering substance-use benefits not to impose more restrictive financial requirements or treatment limits than for comparable medical/surgical care, including how out-of-network access is handled — the leverage in requesting or appealing a single case agreement.. Pair the appeal with your documentation — the failed in-network search, the clinician's medical-necessity statement, and the program's accreditation — because a concrete record beats a general complaint.

There is also a caution worth naming. Because out-of-network billing can be lucrative, some programs push out-of-network admission and single case agreements harder than your clinical situation warrants. Deceptive marketing in this field is real enough that federal enforcers have acted on it — the Opioid Addiction Recovery Fraud Prevention Act gives the Federal Trade Commission authority against deceptive substance-use-treatment marketing, and one such case ended in a settlement 6Ref 6Federal Trade Commission (2025).Enforcing the Opioid Addiction Recovery Fraud Prevention Act: The FTC's settlement with Evoke Wellness.That the Opioid Addiction Recovery Fraud Prevention Act (2018) gives the FTC authority against deceptive substance-use-treatment marketing, and that a $1.9M settlement resulted.. This is where patient brokering hides: a warm pitch to route you somewhere out-of-network can reflect the program's billing incentive more than your need. Pursue an SCA when the clinical case is genuine — not because a program eager for out-of-network billing told you to.
