Mental Health Carve-Out: Find Who Manages the Benefit

Last reviewed: October 7, 2026.

A mental-health carve-out means the health plan hands its behavioral-health benefit to a separate company, which then decides network status, authorizations and often where claims go. Find that administrator first. Being in network with the company on the front of the card, or with the behavioral-health company in general, does not tell you whether you are in network for this client.

How the split shows up

The federal AHRQ integration playbook describes behavioral-health payment administered separately from general health care. Payers say the same in their manuals: one large Blue plan’s provider manual notes that behavioral-health coverage varies by product and employer group and may be administered by another company. In practice we see it in three places:

• The card. A separate behavioral-health phone number, logo or claims address on the back.

• A referral or authorization letter that names the administrator. One integrated health system refers outpatient therapy to an outside behavioral-health company and tells providers to send those claims to that company, not to the health plan.

• The eligibility response, which may show general coverage but no mental-health cost share because another company holds that benefit.

Not every second name on a card is a carve-out. Self-funded employer plans often show a network brand plus a third-party administrator, and a line saying the administrator handles member contact. That describes member services, not necessarily where behavioral-health claims go.

Mistakes we see with carve-outs

• Assuming one contract covers its sister plans. A practice that signed with a large behavioral-health company was told by that company that its agreement covered several plans the company administers, but not the commercial network of a health plan in the practice’s state that contracts separately. Ask the administrator which plans your agreement reaches.

• Calling the old administrator. Employers change carve-out vendors at renewal. A member and a practice both called the outgoing vendor and were told the clinician was out of network, one day before the benefit moved to a new administrator that used a different network.

• Reading one billing setup as the answer for everyone. An administrator can return “out of network” for the practice’s current billing identity while the clinician is individually credentialed. A participation contract or a paid explanation of benefits for that clinician settles which identity to bill under.

Steps to identify the administrator

1. Read the front and back of the current card and any referral or authorization letter. Capture every company name, phone number and payer ID.

2. Run eligibility with the health plan and note whether it returns a mental-health benefit or points elsewhere.

3. Call the behavioral-health number for the member and confirm the administrator for the date of service, the clinician’s network status, authorization rules and the claims payer ID.

4. Set up the EHR payer to match the administrator that adjudicates claims, and keep the medical plan’s details for reference.

Aetna’s behavioral-health directory guidance likewise points members to their plan booklet and the number on their card, and notes some directory providers participate through a vendor agreement. For EAP-to-insurance transitions, where the EAP and the medical plan are often different companies, see switching therapy from an EAP to insurance. For estimating cost share, see how to estimate a therapy deductible, copay, or coinsurance.

Frequently Asked Questions

If I’m in network with the insurer on the card, am I in network for the mental-health benefit?

Not necessarily. When the benefit is carved out, the behavioral-health administrator’s network decides it.

Where do I send claims for a carved-out benefit?

To whichever company the plan or referral says adjudicates behavioral-health claims, using its payer ID. Confirm it for the date of service.
