Third-Party Administrator (TPA)
A third-party administrator is an outside company hired by an insurance carrier to manage specific functions of the claims process, including contractor networks, estimate review, and payment processing.
The Middleman in Claims Processing
A third-party administrator (TPA) is an external company that insurance carriers hire to handle specific parts of the claims process, from managing contractor networks to reviewing estimates to processing payments. Carriers outsource these functions to TPAs for efficiency and scalability. Instead of building and maintaining their own contractor network and review infrastructure, the carrier contracts with a TPA that specializes in those operations.
For contractors, the TPA is often the entity you interact with most directly on managed repair claims, even though the carrier is the one ultimately paying the claim.
What TPAs Manage
TPAs can manage any combination of claims functions: contractor onboarding and credentialing, claim assignment and dispatch, estimate review and auditing, supplement processing, quality assurance inspections, customer satisfaction tracking, and payment processing. The scope of the TPA's authority varies by contract. Some TPAs have broad authority to approve estimates up to certain thresholds. Others route every decision back to the carrier for approval.
Understanding where the TPA's authority ends and the carrier's begins helps you know who to escalate to when a supplement negotiation stalls.
Working With TPAs
TPAs operate on metrics: response time, estimate turnaround, customer satisfaction scores, and claims closed per period. Aligning your workflow with their metrics, such as responding quickly to assignments, submitting clean estimates, and maintaining strong customer reviews, keeps you in good standing. When disputes arise, document everything through the TPA's official channels. If the TPA cannot resolve a supplement dispute, ask the carrier to review the claim directly. The TPA is not the final authority; the carrier is.
Frequently asked questions
A TPA acts as a middleman between the carrier and the contractor. They may manage claim assignments, review estimates, administer contractor networks, process payments, and handle supplement negotiations on behalf of the carrier.
On managed repair and preferred vendor claims, contractors typically interact with the TPA for day-to-day claim processing. The carrier makes coverage decisions, but the TPA handles estimate review, scope discussions, and payment logistics.
