Carve-Outs: Pharmacy, Behavioral Health, Specialty, and More

What Is a Carve-Out?

A carve-out is the practice of separating a specific benefit category — pharmacy, behavioral health, specialty care, vision, dental — from the main health plan and contracting it independently with a specialized vendor. Instead of bundling everything through a single carrier or TPA, the employer manages each high-cost category with the vendor best equipped to control it.

Carve-outs are a natural extension of self-funding. Once an employer has claims data visibility, they can identify which categories are being mismanaged inside a bundled arrangement and extract them for better management.

Pharmacy Carve-Out

The pharmacy carve-out is the most common and typically the highest-value carve-out available to self-funded employers. It separates pharmacy benefits from the medical carrier and contracts directly with an independent, transparent pharmacy benefit manager (PBM).

• Eliminates spread pricing: Independent PBMs charge a transparent per-claim fee rather than marking up drug costs.
• Maximizes rebate pass-through: Independent PBMs pass 100% of manufacturer rebates to the plan rather than retaining a share.
• Enables formulary control: The employer can design a formulary optimized for cost and outcomes rather than accepting the carrier's default formulary.
• Unlocks specialty management: A carved-out pharmacy benefit can be paired with a specialty pharmacy program for high-cost biologics and specialty drugs.

Behavioral Health Carve-Out

Behavioral health — mental health and substance use disorder treatment — is one of the fastest-growing cost categories for employer health plans. It is also one of the most poorly managed inside traditional carrier arrangements. A behavioral health carve-out contracts with a specialized managed behavioral health organization (MBHO) that has deeper provider networks, better clinical management, and stronger outcomes data.

• MBHOs typically have broader behavioral health provider networks than medical carriers, improving access and reducing out-of-network claims.
• Specialized clinical management — utilization review, case management, and care coordination — reduces unnecessary inpatient admissions.
• Mental Health Parity compliance is easier to document and demonstrate with a dedicated MBHO that tracks NQTL analysis separately.
• Virtual behavioral health integration is more seamless with a specialized vendor than inside a bundled carrier arrangement.

Specialty Care Carve-Out

Specialty care carve-outs focus on high-cost, high-complexity conditions — oncology, musculoskeletal, cardiac, transplant — where specialized management can significantly reduce cost and improve outcomes. These programs typically combine Centers of Excellence (COE) contracting with case management and second opinion services.

• Oncology carve-outs: Specialized oncology management vendors provide evidence-based treatment pathways, second opinions, and COE routing for complex cancer cases.
• Musculoskeletal carve-outs: Programs that manage spine, joint, and orthopedic cases with conservative care pathways, second opinions, and ASC steerage.
• Transplant carve-outs: COE contracting for organ transplants with bundled pricing and case management.
• Maternity carve-outs: High-risk pregnancy management programs that reduce NICU admissions and preterm birth rates.

Evaluating the Financial Case

The decision to carve out a benefit category should be driven by data, not intuition. The financial case requires three inputs:

1. 1Current cost: What is your plan currently paying for this category, including all fees, markups, and retained rebates?
2. 2Benchmark cost: What would a specialized vendor charge for the same population, based on your claims data?
3. 3Transition cost: What are the one-time costs of switching — vendor setup, employee communication, coordination infrastructure?

If the annual savings exceed the transition cost within 18 months, the carve-out is financially justified. Most pharmacy carve-outs pay back transition costs within 6 to 12 months.

Managing Carve-Out Complexity

Carve-outs add administrative complexity. Multiple vendors must coordinate on claims, eligibility, and member experience. The most common failure points are:

• Eligibility file management: Each carved-out vendor needs accurate, timely eligibility data. Establish automated eligibility feeds from your HRIS or TPA.
• Claims coordination: Medical and pharmacy claims must be coordinated to avoid duplicate payments and ensure accurate accumulator tracking.
• Member experience: Employees should have a single point of contact for benefits questions regardless of which vendor manages their benefit.
• Vendor accountability: Each vendor must have clear performance guarantees and reporting obligations. Do not assume coordination will happen automatically.
