What is the purpose of a third-party administrator (TPA) in group benefits programs?

• A. To administer claims and day-to-day plan operations, often on behalf of the sponsor or insurer.
• B. To set investment allocations for all participants.
• C. To supervise all HR payroll processing.
• D. To determine employee eligibility for benefits.

Answer: (A)

A TPA’s role is to handle the ongoing administration of a group benefits program, especially processing and paying claims and managing day-to-day plan operations on behalf of the sponsor or insurer. They take care of claim adjudication, member communications, enrollment and eligibility updates, premium billing, and related administrative tasks, ensuring the plan runs smoothly and in line with its terms. This setup lets employers and insurers rely on specialized process and compliance expertise without handling every detail in-house.

Investments are managed by investment professionals or the plan sponsor’s investment team, not the TPA. Payroll processing is a separate HR function, and while eligibility determination is part of benefits administration, the defining purpose of the TPA is the actual claims processing and routine administration that keeps the plan functioning day to day.
