Single Case Agreements: Asking Insurance To Cover An Out-of-Network Specialist
Finding out that the medical specialist you desperately need is "out-of-network" can be a devastating blow. If your health insurance plan is an HMO or a narrow-network PPO, seeing that provider could mean paying 100% of the cost out of pocket. However, you do not have to accept a lack of access to proper medical care. Under federal and state network adequacy laws, your insurer is required to provide you with reasonable access to all covered medical specialties.
If they fail to do so, you have the legal right to request a Single Case Agreement (SCA) or a gap exception. This guide explains how this mechanism works and how to ask your insurance company to cover an out-of-network specialist at in-network rates.
What is a Single Case Agreement and Network Adequacy?
A Single Case Agreement (SCA) is a binding contract between your insurance company and an out-of-network provider. Under an SCA, the insurer agrees to cover your treatment with that specific doctor using your plan’s in-network benefit levels and cost-sharing rates. This means your copays, coinsurance, and deductibles will be calculated as if the doctor were in-network, and the provider agrees not to balance-bill you for the remainder of their standard fee.
Insurers are more likely to grant SCAs when the request is supported by network adequacy standards. Under the Affordable Care Act (ACA) and various state regulations, insurance companies must maintain a provider network that is "sufficient in number and types of providers" to ensure all services are accessible without unreasonable delay. If your insurer has no in-network specialists who can treat your specific condition within a reasonable geographic distance (e.g., 30 miles or 30 minutes driving time), that can support an argument that the network is inadequate and that an out-of-network specialist should be covered.
Step-by-Step Guide to Requesting a Single Case Agreement
Do not schedule your appointment before getting approval, as retroactively securing an SCA is exceptionally difficult. Follow these steps:
1. Document the Lack of In-Network Options
Before calling your insurer, you must prove their network is deficient.
Search your insurer’s online directory for specialists in your area.
Call the listed offices to confirm if they actually accept your plan, are taking new patients, and have expertise in your specific condition.
Keep a detailed call log. If you call five in-network doctors and none can see you within 30 days or none treat your specific condition, write down the dates, times, and names of the representatives you spoke with.
2. Obtain a Physician's Endorsement
An SCA is rarely approved without strong clinical backing. Ask your primary care physician (PCP) or referring doctor to write a Letter of Medical Necessity. The letter should state:
Your specific diagnosis and why it requires specialized care.
Why the listed in-network providers are not clinically appropriate (e.g., "Dr. Smith is a general cardiologist, but the patient requires an electrophysiologist specialized in rare arrhythmias").
Why the proposed out-of-network specialist is uniquely qualified to manage your treatment.
3. Contact Your Insurer's Case Management Department
Call the customer service number on your insurance card and ask to speak with a Case Manager or the Benefits Authorization Department. Avoid talking to front-line customer service agents, as they rarely have the authority to initiate an SCA.

"I am calling to request a network gap exception and a Single Case Agreement for an out-of-network specialist. I have documented that there are no qualified, available providers within my geographic network who can treat my condition. I have a Letter of Medical Necessity from my primary doctor ready to submit."
4. Negotiate the Billing Rates
Once the insurer agrees that their network is inadequate, they must negotiate a rate with the out-of-network specialist. Usually, this is a percentage of Medicare rates or a discount off the provider’s billed charges. Ensure the provider’s billing department agrees to the terms and signs the contract before you undergo treatment.
Key Questions to Ask Your Specialist's Billing Office
Before your first appointment under an SCA, call the specialist’s billing manager and ask:
"Has our insurance company finalized and signed the Single Case Agreement for my upcoming care?"
"Will you accept my plan’s in-network copay and deductible as payment in full under this agreement?"
"Can you confirm that I will not be balance-billed for any charges exceeding the negotiated rate?"
