Behavioral health eligibility and carve-outs

A carve-out is an arrangement in which a health plan separates behavioral health coverage from its general medical coverage and delegates administration to a specialty organization, often called a managed behavioral health organization. The medical payer still enrolls the member, but the behavioral benefit — its network of clinicians and facilities, its prior authorization rules, and its claim-submission address — is managed elsewhere. This structure exists so that behavioral care, which has distinct clinical and utilization patterns, can be administered by an entity focused on it.

The practical consequence is that the information printed on a member's medical card may not describe the behavioral benefit. A separate phone number, payer identifier, or web portal may govern behavioral eligibility and claims. Whether a given plan uses a carve-out, an in-house carve-in model, or a hybrid varies by payer and plan and can change at renewal, so the arrangement is confirmed rather than assumed.

Verifying behavioral eligibility follows the same foundation as any benefit verification, with an added step: identifying the administering entity. An electronic eligibility inquiry to the medical payer may return general coverage while directing behavioral questions to a delegated administrator. Confirming active coverage and effective dates, then locating where the behavioral benefit actually sits, prevents downstream routing errors.

1. 01

   Confirm active coverage and effective dates

   Establish that the member is eligible on the date of service and note effective and termination dates, since retroactive changes affect payment.
2. 02

   Identify the behavioral administrator

   Determine whether behavioral benefits are carved out to a separate managed behavioral health organization, and capture its contact and claim-routing details.
3. 03

   Verify plan type and network status

   Confirm network and plan type against the entity that actually holds the behavioral benefit, not only the medical payer.
4. 04

   Check authorization and referral rules

   Determine whether the specific service requires prior authorization or a referral under the behavioral administrator's rules.
5. 05

   Estimate cost-share and coordination

   Capture patient responsibility and confirm any coordination of benefits where more than one payer is involved.

Because behavioral patients frequently return for recurring visits, re-verifying recurring patients matters: a carve-out relationship or benefit tier that was accurate at intake can change across a plan year.

When behavioral benefits are carved out, a claim sent to the medical payer instead of the delegated administrator can be denied or rejected as wrong-payer, even when the member is genuinely covered. Similarly, an authorization obtained from the wrong entity may not be recognized. These are administrative failures rather than coverage failures, and they are a frequent contributor to behavioral health denials.

Public programs add their own structure. In Medicaid, states may administer behavioral health through managed care organizations, specialized behavioral plans, or fee-for-service, and these arrangements vary substantially by state — see behavioral health under Medicaid. In Medicare, behavioral coverage follows program rules described in behavioral health under Medicare. The specifics are set by CMS and by each state Medicaid agency and change over time.

Federal mental health parity protections shape how behavioral benefits may be structured relative to medical benefits, though which plans and markets these requirements apply to is itself set by federal law and varies by plan type — they do not govern every program uniformly. Where parity applies, it does not eliminate carve-outs, but it constrains how differently a plan may treat behavioral coverage; the behavioral health parity article covers this in depth, and the applicability and scope should be confirmed against the authoritative federal source. Substance use records carry additional confidentiality obligations under 42 CFR Part 2, which can affect how eligibility and claims information is handled.

• Medicaid behavioral administration varies by state program and delivery model.
• Medicare behavioral coverage follows CMS program rules and updates.
• Parity requirements apply to certain plan and market types and, where they apply, constrain but do not remove differences in behavioral benefit design.
• Substance use confidentiality rules add handling requirements beyond standard eligibility.

Most eligibility-related behavioral denials trace to a small set of upstream gaps: the wrong administrator, an expired benefit, a missing authorization under the behavioral entity's rules, or unrecognized medical necessity criteria. Building a consistent front-desk workflow and documenting the behavioral administrator alongside the medical payer reduces rework across the revenue cycle.

Administering entity

The organization that actually manages the behavioral benefit, which may differ from the medical payer under a carve-out.

Benefit tier

How a plan categorizes a service for cost-share and network purposes; behavioral tiers may be set by the delegated administrator.

Routing address

The payer identifier or claim address to which behavioral claims must be sent, distinct from the medical claim address under a carve-out.
