Finding addiction treatment is difficult enough without discovering that the program you are considering is outside your insurance network. In some situations, a health plan and a treatment provider can negotiate a single case agreement, creating a limited exception for one person’s care.
A rehab insurance single case agreement may make treatment more accessible, but it is not an automatic approval or a promise of full payment. The details depend on your plan, clinical needs, available network providers, and the terms accepted by both sides.
For people seeking substance use treatment in California, understanding this process can help prevent delays and unexpected bills. Living Longer Recovery encourages you to ask specific questions, obtain written answers, and separate an insurance benefit check from an actual agreement to cover care.
What is a single case agreement for rehab?
A single case agreement, often called an SCA, is an arrangement between an insurer or health plan and a provider that does not ordinarily participate in that plan’s network. It establishes payment terms for a particular patient and a defined course of treatment.
The agreement may address the reimbursement rate, approved services, dates of care, billing requirements, and the patient’s financial responsibility. It usually does not make the provider an in-network facility for everyone covered by the plan.
Terminology varies. A plan may discuss a network exception, gap exception, letter of agreement, or single-patient contract. These terms can describe related processes, but they are not always interchangeable. Ask what your plan means and which approvals are necessary.
For example, a plan might approve a network exception allowing in-network cost sharing but still need to negotiate payment with the facility. Conversely, a provider payment agreement might exist without reducing your deductible or coinsurance. Both the coverage decision and the payment arrangement matter.
An SCA also does not replace clinical review. The plan may separately require prior authorization and ongoing confirmation that the treatment remains medically necessary.

When might an insurer consider an exception?
Insurers commonly consider whether their existing network can provide appropriate care within applicable access standards. A preference for a particular facility, by itself, may not be enough. A stronger request explains why available network options cannot reasonably meet the person’s documented needs.
Possible reasons to request review include:
- The plan cannot identify an available in-network program offering the clinically recommended level of substance use treatment.
- Listed network facilities report that they are not accepting patients or do not actually provide the required services.
- The person needs coordinated treatment for substance use and a co-occurring mental health condition that available programs cannot appropriately address.
- Travel distance, appointment delays, or other access barriers make the proposed network options unsuitable under the plan’s applicable standards.
- An interruption in established treatment could create a clinically significant risk, and a continuity-of-care process may apply.
These circumstances do not guarantee approval. They provide subjects for a documented review. The clinician’s assessment, plan language, network availability, and applicable law all influence the result.
In California, a directory listing is only a starting point. If a listed facility has no openings or cannot provide the recommended care, record that information accurately. Ask the insurer to help identify an option that is both available and clinically appropriate.

Check your insurance benefits before requesting an agreement
Start with the plan’s member services number and, when available, its behavioral health administrator. Some plans delegate substance use treatment management to another company. The organization processing a request may differ from the name printed most prominently on your insurance card.
Confirm whether the plan covers the recommended setting. Depending on clinical need, care may include withdrawal management, residential treatment, partial hospitalization, intensive outpatient treatment, or standard outpatient services. Coverage for one setting does not establish coverage for another.
Ask these questions before relying on an estimated cost:
- Does my plan include out-of-network substance use treatment benefits, and are there restrictions on where I can receive care?
- Which organization reviews prior authorization requests and network exceptions for behavioral health services?
- Would an approved exception use in-network or out-of-network deductibles, copayments, and coinsurance?
- Which charges count toward my deductible and out-of-pocket maximum under this arrangement?
- Are there separate authorizations or claims for the facility, physicians, medications, laboratory testing, or transportation?
- What documents must the provider submit, and how will I receive the coverage decision?
Request a reference number for each call and keep the representative’s name, date, and explanation. A benefits verification summarizes plan information. It does not guarantee that a claim will be paid or that a requested stay will be approved.
How the single case agreement process usually works
The sequence varies by plan and provider, but most requests involve clinical documentation, an access review, and payment negotiations. Working on these pieces together can reduce avoidable back-and-forth.
1. Obtain an assessment and treatment recommendation
A qualified clinician evaluates the person’s symptoms, substance use history, withdrawal risk, medical concerns, mental health needs, and recovery environment. The assessment supports the recommended level of care. Choosing a facility first should not substitute for determining what care is medically appropriate.
2. Identify the network access problem
Ask the plan for suitable network options and verify whether those programs can accept the person. Document actual responses rather than assuming all network facilities are unavailable. If the issue is a specialized clinical need, explain which required services are missing.
3. Submit the coverage and exception requests
The provider or treating clinician may submit clinical records and authorization materials. The member may need to request a network exception separately. Ask who owns each task, where documents must go, and when the plan expects to make a decision.
4. Negotiate the payment agreement
If the plan is willing to consider the provider, the parties may negotiate reimbursement and billing terms. An insurer’s willingness to review a request does not mean the provider has accepted its rate. Treatment access can depend on both parties reaching an agreement.
5. Confirm the terms before nonurgent admission
When clinically safe, obtain written confirmation before entering care. Review approved services, dates, patient cost sharing, and any remaining conditions. If the approval is verbal, request written documentation and ask whether contracting is complete.
6. Track authorization during treatment
Initial approval may cover only a limited period. Continued treatment can require updated clinical records and additional review. Ask how the facility tracks authorization and communicates changes in covered days or financial responsibility.
Documents that can strengthen a request
A useful request connects the clinical recommendation to the access problem. It should explain why the proposed program can meet the person’s needs and why the available network options cannot do so at the required time or level of care.
Depending on the plan’s requirements, supporting materials may include:
- A current clinical assessment describes symptoms, safety concerns, functional impairment, and the recommended level of care.
- A treatment history explains previous services and outcomes without implying that someone must fail a lower level of care before receiving appropriate treatment.
- A network contact log records facility names, call dates, availability, and the specific reason each option could not meet the identified need.
- A provider summary identifies relevant services, credentials, and the ability to deliver the proposed treatment.
- A transition plan explains how the person will move to a lower level of care when clinically appropriate.
Use accurate, relevant information. Exaggerated urgency or unsupported statements can undermine a request. Medical records should be shared through appropriate channels with any required permissions.
If a support person is helping, confirm whether the insurer needs an authorized representative form. Family involvement can be valuable, but privacy rules may limit what the plan or provider can disclose without consent.
Understand what you could still owe
An approved rehab insurance single case agreement does not necessarily mean treatment is free. You may still owe a deductible, copayments, or coinsurance. Some services may be excluded, billed separately, or outside the agreement’s approved dates.
One important issue is balance billing, which occurs when a provider seeks payment for an amount beyond what the insurer pays and your applicable cost sharing. Whether that is permitted depends on the agreement, the services, and applicable law. Do not assume an exception eliminates it.
Ask the facility and insurer to clarify:
- The agreement states which services are covered and whether separately billing clinicians participate in the arrangement.
- The provider explains whether it accepts the negotiated amount plus applicable patient cost sharing as payment in full for covered services.
- The financial estimate identifies your remaining deductible and the basis used to calculate coinsurance.
- The admission paperwork explains any deposits, refund rules, and responsibility for services that insurance does not approve.
- The provider describes what happens if authorization ends before the recommended treatment is complete.
California and federal surprise-billing protections apply in certain circumstances, but they do not create a universal guarantee for a planned out-of-network rehab admission. Ask how any protections apply to your specific plan and setting.
Keep the final agreement or a written summary of its patient-facing terms, authorization notices, estimates, and explanations of benefits. If a later bill conflicts with those documents, contact both the provider’s billing team and the plan.
California plan rules and review options
California coverage questions depend partly on how your health plan is structured and regulated. Many state-regulated plans fall under the California Department of Managed Health Care or the California Department of Insurance. Self-funded employer plans generally operate under a different federal framework, even when a familiar insurer administers claims.
Medi-Cal has its own systems for accessing substance use treatment, including county-administered services in many situations. Medicare and other coverage arrangements also have distinct rules. A commercial insurance SCA process should not be assumed to apply unchanged to every type of coverage.
California law includes protections relating to medically necessary mental health and substance use disorder treatment for many state-regulated plans. However, those protections do not mean every requested provider or service must be approved. The plan type, clinical evidence, and reason for denial remain important.
If you cannot determine who regulates your coverage, ask member services or your employer’s benefits administrator. The relevant regulator or benefits authority can explain complaint and review pathways that may apply. This information is educational and is not legal advice.
What to do if the request is denied
First, obtain the denial in writing. Identify whether the dispute concerns medical necessity, lack of out-of-network benefits, the network exception, or unsuccessful payment negotiations. These problems require different responses.
If the plan says an appropriate network provider is available, request its name and confirm availability. If that option cannot meet the documented need, send the new information back to the reviewer.
If the denial concerns clinical necessity, ask the treating clinician to review the stated rationale. Additional records or a clinician-to-clinician discussion may help clarify the recommendation, although they do not guarantee reversal.
Follow the appeal instructions and deadlines in the notice. Depending on the plan and issue, an internal appeal, external review, independent medical review, or regulator complaint may be available. Request expedited review when the applicable urgency criteria are met, rather than simply because a preferred admission date is approaching.
Meanwhile, ask about safe alternatives. An available network program or another covered level of care may prevent a treatment gap. Do not delay emergency care while waiting for an insurance exception.
Plan for urgent needs and treatment transitions
Insurance negotiations should not determine whether someone receives emergency medical attention. Alcohol or sedative withdrawal can be dangerous, and overdose or severe psychiatric symptoms require prompt assessment. Call 911 for an emergency. For a suicide or mental health crisis, call or text 988.
For nonemergency care, ask what happens after the initially approved treatment period. Residential approval does not automatically cover outpatient follow-up, and approval for one provider may not transfer to another.
A practical transition plan considers follow-up appointments, prescribed medications, transportation, housing stability, and ongoing recovery support. Clarify which services need new authorization and whether the next provider is in network. Planning early can make the move between levels of care less disruptive.
Questions to ask Living Longer Recovery
When contacting Living Longer Recovery, have your insurance card and a brief description of the treatment need available. You do not need to understand every insurance term before asking for guidance.
Ask whether your specific plan can be reviewed, whether a single case agreement might be relevant, and what information would be needed to explore it. Confirm any network status directly with your insurer, since participation can differ by plan and change over time.
You can also ask who would coordinate an exception request, what costs remain uncertain, and whether written approval is needed before admission. No provider can guarantee an insurer’s decision simply by checking benefits.
