The Role of a Third Party Administrator in Commercial Insurance: How TPAs and TPA Firms Handle Third Party Administration

A TPA is an independent company that handles claims administration and related administrative functions for an insurer or a self-insured employer, without taking on the insurance risk itself. It processes insurance claims, keeps records, and handles reporting, but the carrier or the employer's own funds pay the claims. For agents, knowing what a TPA does (and does not do) matters most when a client moves from a guaranteed-cost program to self-funding, a large deductible, or a self-insured retention, because the quality of the administrator then drives much of the client's loss cost. The same title also covers retirement plan administration firms, which work with the recordkeeper and financial advisor to run defined contribution plan operations such as 401(k) plan annual compliance testing, Form 5500 filings, vesting schedules, participant loans, and distributions so retirement plans avoid IRS penalties. That is a separate business.

Self-funded health and benefit plans

In employee benefits management, self-funded employers use a TPA in place of the claims department a fully insured health insurance carrier would provide. Typical services include enrollment and eligibility (often fed by files from the employer's payroll provider), claims processing, access to rented provider networks, utilization review and other medical management, care navigation for members, and coordination with the stop-loss carrier on large claims. Many also run flexible spending accounts and wellness programs. Some carriers sell the same work as an administrative services only (ASO) contract. The employer controls plan design as the plan sponsor and usually keeps fiduciary responsibility under ERISA requirements, which the Department of Labor enforces, so the contract and the plan documents should say who decides final claim appeals.

Workers compensation and liability claims

On the property and casualty side, self-insured companies and employers with large deductible programs hire a TPA to handle claims under workers' compensation, auto, and commercial liability insurance. The TPA's claims adjuster investigates each loss, sets reserves, manages medical care and return to work on comp files, and works with defense counsel when a claim is litigated. Larger or suspicious losses may call for an outside claims investigator or forensic accounting services. The client or its carrier funds the claims, often through a loss fund the TPA draws on, and the TPA reports paid and reserved amounts so the agent and underwriter can see how the program is running. It often handles government reporting, such as Medicare Section 111 reports on comp and liability claims. Many states require the TPA and its adjusters to hold licenses. Well-known TPAs include Sedgwick, Gallagher Bassett and ESIS (part of Chubb).

What to check before a client signs

Ask the administrator for:

• State TPA and adjuster licenses where the client operates
• Claim handling standards, caseloads and contact times
• Data security controls and breach notification terms
• Errors and omissions coverage and a fidelity bond
• Sample reports and the client's access to its own claims data
• Fee basis, contract length and data handover at termination

Treat the contract as part of the insurance program, and judge the vendor on service and controls before price, since weak handling can raise health care costs or claim costs far more than a lower fee saves. The agreement should list the administrative tasks the TPA owns and what the client keeps, set service levels with remedies, and explain how the TPA meets its compliance obligations under federal regulations such as the HIPAA privacy rules that apply to health plan data. Review results at least once a year with one person at the client assigned to administrative oversight, so the client can see whether moving the administrative work out of house actually reduced its administrative burden.

Frequently Asked Questions

What is the difference between a TPA and an insurance company?

An insurer underwrites the risk, issues the policy, and pays claims from its own funds. A TPA only administers claims and services for whoever carries the risk, so it does not underwrite coverage or guarantee claim payments.

How is a TPA different from an independent adjuster?

An independent adjuster usually handles individual claims that a carrier assigns, often for a fee per file. A TPA runs the whole claims program for a client, including intake, payments, reserves, reporting, and vendor management, and employs its own adjusters to do it.

Who pays the claims in a self-funded plan?

The employer pays the claims. The TPA processes them and issues payments from an account funded by employer contributions and any employee share. Stop-loss coverage, bought separately, reimburses the employer for claims above set limits.

Does a TPA handle premium billing?

Sometimes. For fully insured group insurance policies, the carrier normally bills premium, but some TPAs handle billing, enrollment, and eligibility for carriers or associations. A self-funded plan has no premium in the usual sense, so the administrator bills the employer for its fees and for claim funding instead.

What does a TPA do in a large deductible program?

A TPA handles the claims while the carrier issues the policy and pays losses, then bills the insured back for amounts within the deductible. The carrier usually approves the TPA and sets claim-handling standards, because it still owes the claims if the insured cannot reimburse it.
