A single case agreement, or SCA, is a one-time contract between your insurance company and an out-of-network provider that covers your treatment at in-network or negotiated rates, for you alone. It is one of the least known and most powerful tools in behavioral health coverage, because it can turn an out-of-network treatment center into an in-network experience for a single admission. Here is when insurers grant them, how to request one, and what to expect.
How a single case agreement works
Normally, network status is fixed: a provider is in or out, as explained in in-network vs out-of-network rehab. An SCA creates an exception. The insurer and the specific facility agree, in writing, on a rate and terms for your specific episode of care. Once signed, your claims typically process at in-network benefit levels: the in-network deductible, the in-network coinsurance, and the in-network out-of-pocket maximum.
When insurers grant single case agreements
Insurers grant SCAs when covering the out-of-network provider serves their obligations or interests. The strongest grounds are:
Network inadequacy
The plan’s network contains no appropriate, available provider for the medically necessary service. That can mean no in-network residential program within a reasonable distance, no availability without a long waitlist, or no program offering what you clinically need, such as dual diagnosis care or a couples track. Network adequacy is the most common and most successful argument.
Continuity of care
You are already established with a provider who leaves the network, or you need a seamless step from one level of care to another that the network cannot provide without disruption.
Clinical specificity
A documented clinical need that in-network options cannot meet. The more specific and well-documented the need, the stronger the request.
How to request one, step by step
- Verify your benefits first, so you know your baseline out-of-network coverage and what an SCA would improve. Use the insurance verification guide.
- Document the gap: which in-network programs were contacted, their waitlists or clinical limitations, and the clinical recommendation for the level of care, supported by medical necessity criteria.
- Let the treatment center lead. SCAs are provider-to-insurer negotiations, and experienced admissions and utilization review teams request them routinely, with the billing codes, rates, and language insurers expect.
- Get it in writing before admission: covered services, rate, number of days initially authorized, and how extensions will be reviewed.
Realistic expectations
SCAs are granted case by case, and no ethical provider will promise one. Approval odds rise when the network gap is real and documented, and fall when comparable in-network care is genuinely available. Two honest notes: first, an SCA is not the only path, since PPO out-of-network benefits alone often make treatment attainable, especially once the out-of-pocket maximum caps your exposure, as shown in how much does rehab cost with insurance. Second, HMO and EPO members should always ask, because an SCA is sometimes the only route those plans have to an out-of-network program, including one out of state.
Single case agreements and Highmark
Highmark members, like members of other Blue plans, can pursue SCAs through the facility they want to attend. Whether an SCA, standard PPO Blue out-of-network benefits, or BlueCard travel coverage is the best vehicle depends on your specific plan, and that is exactly what a free verification call sorts out. Our team requests and negotiates these agreements as part of admissions: start at the Highmark rehab coverage page or verify your benefits, and we will tell you which path your plan supports.
