Key Takeaways
- The TPA is the operational backbone of a self-funded plan — it processes claims, manages data, and coordinates every other vendor relationship.
- Not all TPAs are equal: reporting quality, cost-containment program access, and vendor independence vary dramatically.
- Many TPAs earn undisclosed revenue from vendors they recommend — always require full compensation disclosure.
- Switching TPAs is disruptive but sometimes necessary — a poor TPA limits everything you can accomplish with your plan.
- The right TPA is a strategic partner, not just a claims processor — they should proactively surface cost drivers and opportunities.
What a TPA Actually Does
A third-party administrator (TPA) is the operational hub of a self-funded health plan. While the employer bears the financial risk and the stop-loss carrier provides catastrophic protection, the TPA handles the day-to-day mechanics: processing medical and pharmacy claims, managing the member experience, producing plan reports, coordinating with the provider network, and filing stop-loss reimbursement requests.
In a carrier ASO (administrative services only) arrangement, the carrier itself serves as the TPA — processing claims through its own systems while the employer funds the claims account. Independent TPAs are separate companies that provide the same administrative services without the carrier's network ownership or financial interests.
The distinction between an independent TPA and a carrier ASO matters strategically. A carrier ASO gives you access to the carrier's network and systems — but the carrier controls the data, the vendor relationships, and the cost-containment programs. An independent TPA gives you more flexibility to choose your own network, PBM, and cost-containment vendors.
Think of your TPA as the general contractor of your health plan. They do not build everything themselves — they coordinate the network, PBM, stop-loss carrier, and specialty vendors. The quality of that coordination determines whether your plan runs smoothly or generates constant member complaints and administrative headaches.
Many employers select their TPA based on their broker's recommendation without understanding that the broker may earn significant revenue from that TPA relationship. Always ask your broker: "What do you earn from this TPA — directly or indirectly?" The answer may surprise you.
Evaluating TPA Reporting Capabilities
Claims data is the most valuable asset a self-funded employer has — and the TPA controls access to it. The quality of your TPA's reporting capabilities determines how much visibility you have into your plan's cost drivers and how effectively you can act on that information.
- Real-time data access: can you log in and see claims as they are processed, or do you wait for monthly reports?
- High-cost claimant reports: can you identify members with claims above a threshold without requesting a custom report?
- Diagnosis and procedure analysis: can you see what conditions and procedures are driving costs?
- Pharmacy integration: are medical and pharmacy claims in the same reporting environment?
- Data export: can you export raw claims data for independent analysis or to share with cost-containment vendors?
- Benchmarking: does the TPA provide peer benchmarks so you can compare your plan's performance to similar employers?
Before signing a TPA contract, ask for a live portal demonstration — not a recorded video or a slide deck. Log in yourself and try to run a high-cost claimant report, a diagnosis frequency report, and a year-over-year trend report. If any of these require a custom request or a phone call, the reporting is not adequate for active plan management.
Some TPAs charge additional fees for data extracts, custom reports, or access to raw claims files. These fees are often not disclosed upfront. Ask specifically: "What does it cost to receive a full claims data extract in a standard format?" If the answer is more than a nominal fee, negotiate it out of the contract before signing.
HIPAA does not prevent your TPA from sharing your own plan's claims data with you. If a TPA tells you they cannot share certain data for HIPAA reasons, they are either misinformed or using HIPAA as a shield for data they do not want you to see. You are the plan sponsor — you have the right to your plan's data.
TPA Compensation and Conflicts of Interest
TPA compensation is more complex than a simple per-employee-per-month administrative fee. Many TPAs earn additional revenue through arrangements that are not always disclosed to the employer — and some of those arrangements create conflicts of interest that affect the advice and vendor recommendations you receive.
- Administrative fees: the base PEPM fee for claims processing, member services, and reporting.
- Network access fees: revenue the TPA earns for steering clients to specific rental networks.
- PBM revenue sharing: fees paid by PBMs to TPAs for client referrals or preferred placement.
- Stop-loss placement fees: compensation from stop-loss carriers for placing business.
- Vendor referral fees: payments from cost-containment vendors, care management companies, or specialty programs.
Under ERISA Section 408(b)(2), service providers to ERISA plans are required to disclose their compensation if it exceeds $1,000. This includes TPAs. Request a full 408(b)(2) disclosure from your TPA and review every line item. If your TPA cannot produce this disclosure, they may be in violation of ERISA.
The cleanest TPA relationships are fee-only: a flat PEPM administrative fee with no revenue sharing from any vendor. These TPAs have no financial incentive to steer you toward specific networks, PBMs, or cost-containment programs. They exist — ask your broker to include at least one fee-only TPA in any competitive evaluation.
Revenue sharing between TPAs and vendors is not inherently illegal — but it must be disclosed. The problem is not that the TPA earns revenue from vendors; it is when that revenue influences recommendations in ways that cost the employer more than a neutral recommendation would. Disclosure lets you evaluate the conflict; secrecy makes it a liability.
Independent TPA vs. Carrier ASO
| Factor | Independent TPA | Carrier ASO |
|---|---|---|
| Network access | Rents access to one or more networks | Uses carrier's proprietary network |
| Data ownership | Employer has full data rights | Carrier controls data; access may be limited |
| Vendor flexibility | Employer chooses PBM, stop-loss, cost-containment vendors | Carrier ecosystem preferred or required |
| Cost-containment programs | Employer selects best-in-class vendors | Carrier's programs; may not be best-in-class |
| Administrative fee transparency | Typically more transparent | Often bundled; harder to unbundle |
| Member experience | Varies by TPA quality | Carrier brand recognition; consistent experience |
| Stop-loss placement | Independent market access | Carrier may offer captive stop-loss |
Carrier ASOs are not inherently inferior — for employers who value simplicity, brand recognition, and a single point of contact, they can be the right choice. The trade-off is flexibility and data access. If you want to implement reference-based pricing, carve out your PBM, or use specialty cost-containment vendors, an independent TPA gives you more room to maneuver.
Some carrier ASO contracts include "most favored nation" clauses or network exclusivity requirements that prevent the employer from using competing networks or cost-containment programs. Read the ASO contract carefully before signing — these clauses can significantly limit your ability to manage costs.
When to Switch TPAs
Switching TPAs is disruptive — it involves migrating claims history, re-enrolling members, and retraining HR staff. But staying with a poor TPA is more expensive in the long run. The right time to evaluate a TPA switch is at plan year renewal, with a 6-month runway to complete the transition.
- Reporting is inadequate: you cannot get the data you need to manage costs without custom requests.
- Claims processing errors are frequent: members are receiving incorrect EOBs, claims are being denied incorrectly, or stop-loss filing is delayed.
- Vendor conflicts are undisclosed: you discover the TPA is earning revenue from vendors they recommended without disclosing it.
- Cost-containment programs are limited: the TPA's preferred vendor relationships prevent you from implementing better programs.
- Member satisfaction is low: employees are frustrated with the member services experience.
Before switching TPAs, negotiate a data portability clause into your current contract. You are entitled to your claims history in a standard format — but some TPAs make data extraction difficult or expensive at termination. A data portability clause ensures a clean transition and protects your ability to use historical data with a new TPA.
When issuing a TPA RFP, include a mandatory site visit or live system demonstration as part of the evaluation. References from current clients of similar size are essential. Ask specifically: "How long does it take to get a custom report?" and "What is your claims processing accuracy rate?" Vague answers are a red flag.
Your Action Steps
- 1Request a full ERISA 408(b)(2) compensation disclosure from your current TPA — every revenue stream, not just the administrative fee.
- 2Log into your TPA's reporting portal and attempt to run a high-cost claimant report and a diagnosis frequency report without assistance.
- 3Ask your TPA: "What vendors do you earn revenue from, and how much?" Document the answer in writing.
- 4Review your TPA contract for data portability provisions — what happens to your claims data if you terminate?
- 5If you are evaluating a new TPA, require a live portal demonstration and references from at least 3 clients of similar size.
- 6Compare your TPA's administrative fee to market benchmarks — typical range is $15 to $35 PEPM depending on services included.
