Single Case Agreements: A Guide on request, Negotiate, Billing SCAs for Out-of-Network Care

Negotiated SCA rates often run 30-50% higher than standard in-network reimbursement, but each agreement covers only one patient for one episode of care, it can never be reused. Getting paid correctly means referencing the SCA authorization number on every claim, billing standard CPT/HCPCS/ICD-10 codes at the negotiated rate (not your standard OON rate), and tracking expiration dates closely, since an expired or mismatched agreement is one of the most common causes of denied SCA claims. Full process, negotiation tactics, billing rules and stats below.

In I-Med Claims, we see single case agreements popping up all the time in behavioral health, addiction treatments and specialty medical billing, and we see just as many practices leave money on the table just because they don’t know how to request one, negotiate it, or bill it perfectly and precisely. In this guide we will pull up together what actually works, backed by statistics so that your practice won’t lose out-of-network patients and revenue to a process usually most billing teams never fully master.

What is a Single Case Agreement?

A single case agreement (SCA in short) is a one-time, patient-specific contract between an out-of-network provider and an insurance payer that authorizes treatment for a single patient at a negotiated reimbursement rate. Unlike a standard network participant agreement, which covers every patient enrolled in that payer’s plans for a multi-year contract term, an SCA applies to one patient, for one episode of care, at its own rate, authorized services, and length-of-stay terms.

SCAs function as a substitute for previous authorization when a provider isn’t in-network. A prior authorization requires a formal payer contract, an out-of-network clinician doesn’t have one, so the SCA fills up that gap and establishes payment terms directly.

SCA Vs. Standard Network Agreement Vs. Standard Out-of-Network Benefits

Why Single-Case Agreement for Medical Providers, Patients and Payers

Lets start first with providers then patients and payers and understand what does it mean to every single one of them:

For Providers:

Single-case agreement for medical providers reduces the denials that are connected to out-of-network services, easy reimbursement, and also because rates are not restricted by fixed in-network schedules, it allows providers to negotiate considerably higher payment. Reported negotiations rates commonly agreed on 30-50% above standard in-network reimbursement. For practices in the process of joining a network, an approved SCA also lets them start treating patients immediately instead of waiting out in a credentialing line, which our medical credentialing and enrollment services team sees stretch 45 to 90+ days on a route basis.

for Patients:

An SCA is generally the only way for a patient to maintain a continuum of care, continue seeing his preferred provider after changing insurance, see a specialized provider outside the network, or find a nearer provider than traveling far for the treatment.

for Payer:

An SCA is always cost-effective and more dependable compared to the eternal battle. An SCA is always a once-off deal rather than recurrent prior authorization, and it satisfies the payer’s members if there are no enough in-network alternatives available, and this is important because network adequacy in behavioral health continues to be a chronic and well-recognized problem. The MHPAEA mandates that payers have equivalent behavioral health and medical/surgical networks, but most of them fail to meet this requirement, particularly adolescent care, trauma-informed programs, and medication-assisted treatment.

Why This Matters More In Behavioral Health

Arround 30% of the US adults with a mental health need did not receive care in 2020 due to inadequate insurance coverage, a gap that single case agreements exist usually to close when no in-network specialist, program type, or geographic option is available. This is exactly why SCAs show up so heavily in behavioral health billing: network adequacy gaps are the rule, not the exception, in addiction treatment and specialty mental health care.

When is a Single Case Agreement Needed?

How SCA Process work

1. Identify the requirement: first confirm the patient has coverage, the provider is out-of-network, and no adequate in-network alternative exists.
2. Gather all documents: like treatment history, clinical justification, diagnosis codes and proof of network inadequacy.
3. Contact the Payer: send a request (usually a PDF form) for the reason(s) for which out-of-network care is highly critical.
4. Payer Review:  The insurance company reviews the necessity, in-network capability, and the credentials of the provider.
5. Set the Terms: The rate, services that are authorized, length of stay, and concurrent review timing are all negotiated individually.
6. Sign the Agreement: Once the terms are set, all of the parties involved sign a legal agreement for the specific episode.
7. Submit Claims under the SCA: use the specific SCA authorization number and use proper CPT/HCPCS/ICD-10 coding and modifiers for the claims.

Approval Timelines

Time frames for approval differ greatly depending on urgency and insurance carrier:

In emergencies, some institutions allow the patient to be admitted first then go for the SCA retrospectively, but there is always a financial risk involved, hence such measures should never be the first choice unless there is a signed financial agreement in place.

Single-Case Agreement Negotiations: What influences Moves The Rate

A successful single-case agreement negotiation comes down to documentation, persistence, and knowing exactly what you ask for. 

Explain the specific, documented reason out-of-network care is important: vague justification is simply the biggest reason SCA requests stall or get denied.

• State the total bill: proper CPT codes, modifiers, number of visits, and treatment length ensure there is nothing left to haggle about for the insurance company.

• Respond to Counteroffers rapidly: This is all about rounds of bargaining, slow replies mean you lose the patient through a break in continuity.

• Find comparable local fees: The insurance company benchmarks based on other providers providing services similar to yours; arriving prepared puts you at an advantage.

• Be persistent but do not damage the relationship: Insurers generally go for standard terms first, an official follow-up is all it takes to secure better terms.

• Define services specific to the agreement: vague terms around what’s covered under the per diem or session rate are one of the most common sources of later billing issues.

Cases involving recent inpatient hospitalization or documented high-acuity risk (e.g. safety concerns usually) tend to move through quicker approval, based on urgency payers recognize in those situations.

Single-Case Agreement Billing: Getting paid Correctly

Single-Case Agreement billing follows the same coding rules as any other claim. The difference is entirely in the payment terms, not the coding mechanics.
