Choosing a third-party administrator

What gets administered

TPAs work for whoever carries the risk — a self-funded employer plan, a captive, a risk retention group or an insurer. Depending on the line, that means claims intake, adjudication and payment, loss reporting, eligibility and enrollment, COBRA and spending-account administration, cost containment, and reporting to stop-loss or reinsurance carriers. Health benefits, workers' compensation and liability claims are different businesses, so start from the lines you actually need administered.

Who keeps the responsibility

An administrator does not take on the risk. Under the NAIC model law that many states follow, a TPA must act under a written agreement with the payor, hold funds in a fiduciary capacity and keep records the payor can inspect, and an insurer remains responsible for the TPA it uses. For a self-funded health plan, the employer's duties as plan sponsor stay with the employer. See self-funded health plan solutions for how those roles fit together.

Questions for a shortlist

Which states license you for our lines? What turnaround and accuracy standards will you commit to, and how are they reported? Can we reach our claims data directly, in what format, and do we keep it if we leave? Who prepares stop-loss or reinsurance filings? How are fees set — per claim, per employee or a percentage — and what costs sit outside them?
