A carve out in health insurance refers to a specific benefit or service that your insurer separates from the main health plan and assigns to a different, specialized company to manage. Instead of one insurer handling everything, certain services like mental health care, prescription drugs, or vision care get managed by a separate vendor with expertise in that area.
Think of it this way. You sign up for a health insurance plan that covers doctor visits, hospital stays, and lab work. But when you need therapy for anxiety or a prescription filled at the pharmacy, a completely different company handles those claims. Your main insurer “carved out” those services and gave them to a specialist vendor.
This matters to you because it directly affects how you file claims, which providers you can see, and what you pay out of pocket. If your plan uses a carve out for behavioral health, you may need to call a different phone number, use a different provider network, and meet a separate deductible for mental health visits.
Carve outs exist because insurers believe specialized vendors can manage certain high cost or complex services more efficiently. For example, a pharmacy benefit manager (PBM) that focuses entirely on prescription drugs may negotiate better prices than a general health insurer. Similarly, a behavioral health company that specializes in mental health may offer deeper provider networks for therapy and counseling.
About 13.5% of health plan sponsors use a spousal carve out, and roughly 35% of commercially self insured members receive carved out pharmacy benefits, according to industry surveys. These numbers show that carve outs play a significant role in how Americans receive and pay for health care today.
Whether you get insurance through your employer, the ACA marketplace, Medicare, or Medicaid, understanding carve outs helps you avoid surprise bills and get the most from your coverage.
How Does a Health Insurance Carve Out Work?
A carve out works by splitting specific services away from the main health insurance contract and placing them under a separate agreement with a specialized vendor.
Your employer or insurer identifies a benefit category that requires specialized management. Common examples include pharmacy benefits, mental health services, or substance use disorder treatment. They then contract with a separate company that specializes in that benefit. That vendor builds its own provider network, sets its own utilization rules, and processes claims independently.
When you need a carved out service, you use the vendor’s network and follow their authorization rules instead of the rules from your primary health plan. This means you may have a different set of in network providers, a separate customer service line, and potentially different copays or deductible requirements.
For example, imagine you visit your primary care doctor for a checkup and also discuss symptoms of depression. Your doctor’s visit goes through your main health insurance carrier. But when your doctor refers you to a therapist, that referral goes through your behavioral health carve out vendor. You now deal with two separate companies for care received on the same day.
The Claims Process With a Carve Out
Filing claims under a carve out plan involves an extra step that many people miss. You receive a service covered under the carve out, such as a therapy session or a prescription. The provider bills the carve out vendor directly, not your main health insurer. The carve out vendor processes the claim based on its own network agreements and benefit rules. You receive a separate Explanation of Benefits (EOB) from the carve out vendor.
This separation means you should keep track of two sets of paperwork: one from your main insurer and one from each carve out vendor your plan uses.
What Types of Services Do Health Plans Commonly Carve Out?
Insurance companies carve out services that benefit from specialized management or that carry high financial risk. The most common carve outs include:
Mental and behavioral health services. This remains the most well known type of carve out. Your health plan may cover general medical care while a separate behavioral health organization manages therapy, psychiatric visits, substance use treatment, and counseling services. Many parents discover that conditions like ADHD evaluation, developmental delays, and even anxiety treatment fall under a behavioral health carve out, which sometimes surprises families who expect their pediatrician’s office to handle the full claim.
Prescription drug (pharmacy) benefits. Many employer sponsored plans separate pharmacy coverage from medical coverage. A pharmacy benefit manager handles drug formularies, negotiates rebates with manufacturers, and processes prescription claims. When your pharmacy benefit gets carved out, you may have a separate pharmacy card, a different deductible for medications, and a distinct formulary.
Vision care. Eye exams, glasses, and contact lenses often get carved out to specialized vision care companies like VSP or EyeMed. Your main health plan handles medical eye conditions, but routine vision care flows through a different vendor.
Dental care. Similar to vision, dental benefits frequently operate as a carve out with their own network and benefit limits.
Specialty services. Some plans carve out areas like oncology care, chronic disease management, rehabilitation services, or organ transplant coordination. These complex medical needs often benefit from vendors who focus exclusively on those conditions.
Spousal carve out. This refers to an employer’s decision to exclude spouses from their health plan entirely, especially when the spouse has access to coverage through their own employer. About 7.1% of health plan sponsors include a spousal carve out according to the 2024 International Foundation of Employee Benefit Plans survey.
Carve Out vs. Carve In: What Is the Difference?
Understanding the difference between a carve out and a carve in helps you evaluate your health plan options more effectively.
Feature | Carve Out | Carve In |
Management | Separate vendor manages the benefit | Main insurer manages all benefits together |
Provider network | Separate network for carved out services | Single unified network for all services |
Claims processing | Two or more claims systems | One claims system |
Deductibles | May have separate deductibles | Usually one combined deductible |
Care coordination | Requires communication between vendors | Integrated care coordination |
Best for | Large employers, complex benefits | Smaller employers, simpler administration |
Cost control | Can isolate and manage high cost areas | Simpler but less targeted cost management |
Member experience | More complex navigation | Simpler, single point of contact |
A carve keeps all benefits under one insurance carrier. Your medical visits, therapy sessions, prescriptions, and specialist appointments all process through the same company. You have one member ID card, one customer service number, and one set of benefit rules.
A carve out separates specific benefits and hands them to specialized vendors. This can lead to better pricing and deeper expertise, but it adds complexity for members.
Research from Cambia Health Solutions found that members with carved in pharmacy benefits had roughly 4% lower medical costs per member per year and 15% lower hospitalization odds compared to those with carved out pharmacy benefits. These findings suggest that integrated care can produce better health outcomes in some cases, though results vary by plan design and population.
Who Benefits From Health Insurance Carve Outs?
Carve outs serve different stakeholders in different ways. Here is who tends to benefit and how:
Large employers and plan sponsors often benefit the most. By carving out high cost services like pharmacy or behavioral health, they isolate financial risk and work with vendors who specialize in managing those specific costs. A dedicated pharmacy benefit manager may negotiate manufacturer rebates and drug discounts that a general health insurer cannot match.
Members who need specialty care may benefit from deeper provider networks. A behavioral health carve out vendor typically maintains a larger network of therapists, psychiatrists, and counselors than a general medical insurer would.
Self insured employers gain flexibility through carve outs. They can mix and match vendors for different benefit categories, choosing the best option for pharmacy, behavioral health, and medical coverage separately.
However, carve outs also create challenges. Members must navigate multiple systems, and coordination between a primary care doctor and a carved out specialist can break down. A situation can arise where the main medical plan classifies a diagnosis as “behavioral health” and refers it to the carve out, while the behavioral health vendor rejects it as a “medical” issue, leaving the patient caught between two companies.
How Do Carve Outs Affect Your Out of Pocket Costs?
Your wallet feels the impact of carve outs in several ways:
Separate deductibles. If your pharmacy benefit gets carved out, you may need to meet a separate pharmacy deductible before coverage kicks in, on top of your medical deductible.
Different copays and coinsurance. Carved out services may come with their own cost sharing schedule. Your therapy copay under a behavioral health carve out might differ from your copay for a medical specialist visit.
Out of pocket maximum considerations. Check whether your carved out benefits count toward the same annual out of pocket maximum as your medical benefits. Under the ACA, most plans must cap your total out of pocket spending, but how carve outs interact with these limits varies by plan.
Network confusion penalties. If you accidentally see a provider who belongs to your main insurer’s network but falls outside your carve out vendor’s network, you could face out of network charges.
Real Life Scenario: How a Carve Out Affects a Family
Sarah works for a midsize company with a behavioral health carve out. Her daughter Emma starts experiencing anxiety, so Sarah takes her to their pediatrician, who recommends weekly therapy.
Sarah searches her main health insurance provider directory and finds a child psychologist nearby. Three weeks later, Sarah receives a bill for $450 because the psychologist was in network for the medical plan but out of network for the behavioral health carve out vendor.
After calling the carve out company and finding an in network therapist, Sarah gets Emma into treatment with a $30 copay per session instead. This scenario plays out for thousands of families every year. Always verify which vendor manages the service you need and search their specific provider directory.
How Do Carve Outs Relate to Medicare and Medicaid?
Carve outs play a major role in government funded health programs as well.
Medicare uses a form of carve out for prescription drugs. Original Medicare (Parts A and B) covers hospital and medical services, while Part D covers prescription medications through separate private insurance carriers. Many Medicare Advantage plans integrate these benefits, but the traditional Medicare structure effectively carves out pharmacy coverage.
Medicaid programs across many states rely heavily on carve outs. States frequently carve out mental health services, substance use disorder treatment, and pharmacy benefits from their managed care contracts. A separate behavioral health organization may manage all Medicaid mental health services in a state while managed care organizations handle physical health care.
The Mental Health Parity and Addiction Equity Act (MHPAEA) requires that mental health and substance use disorder benefits face no greater restrictions than medical and surgical benefits. This law applies whether mental health services get managed through a carve out or a carve in arrangement.
Comparison: Common Carve Out Types and What They Mean for You
Carve Out Type | Who Manages It | What It Covers | What to Watch For |
Behavioral Health | Specialty behavioral health vendor | Therapy, psychiatry, substance use treatment, counseling | Separate provider network; some conditions may get classified differently |
Pharmacy | Pharmacy Benefit Manager (PBM) | Prescription drugs, specialty medications | Separate formulary, possible mail order requirements, different deductible |
Vision | Vision care company (e.g., VSP, EyeMed) | Routine eye exams, glasses, contacts | Medical eye conditions still go through main health plan |
Dental | Dental insurance carrier | Preventive, basic, and major dental services | Annual benefit maximum, separate waiting periods |
Specialty Care | Disease management vendor | Oncology, transplant, chronic disease programs | May require case manager coordination, pre authorization |
Spousal | Employer decision | Excludes spouse from plan eligibility | Spouse must find coverage elsewhere; ACA does not require spousal coverage |
Frequently Asked Questions
No. A carve out does not eliminate coverage. It moves management of that benefit to a specialized company. You still receive coverage, but you access it through a separate vendor with its own network and rules.
In most cases, you cannot opt out of a carve out. The carve out structure gets built into the plan design by your employer or insurer. If you want different arrangements, you would need to choose a different plan during open enrollment.
Check your Summary of Benefits and Coverage (SBC) document. Look for references to separate administrators for pharmacy, behavioral health, or other services. You can also call your insurance company or ask your employer’s benefits team.
Carve outs primarily save money for the plan sponsor (usually your employer) by managing high cost benefit areas more efficiently. Whether you see lower premiums depends on your employer’s plan design and how they pass savings to employees.
Yes, carving out mental health benefits remains legal. However, the Mental Health Parity and Addiction Equity Act requires that mental health and substance use disorder benefits receive equal treatment compared to medical and surgical benefits. This means your carve out vendor cannot impose stricter copays, visit limits, or authorization requirements than your medical plan applies to comparable physical health services
If your provider sends a claim to your main insurer instead of the carve out vendor, the claim will likely get denied. Contact both companies and your provider’s billing office to redirect the claim to the correct vendor.
Key Takeaways
Health insurance carve outs separate specific benefits from your main plan and assign them to specialized vendors. This arrangement can improve cost management and provide deeper expertise for complex services like mental health care and prescription drugs. However, carve outs add complexity for members who must navigate multiple networks, deductibles, and claims processes.
Always verify which company manages each benefit in your plan. Search the correct provider directory before booking appointments. Track your out of pocket spending across all vendors. And ask your HR department or insurer about carve outs during open enrollment so you know exactly what to expect.
