What Is a Third-Party Administrator (TPA)?
A third-party administrator is a company your employer hires to manage health insurance claims, benefits administration, and customer service for a self-funded plan. The TPA handles everything from claim processing to appeals and denials, but does not assume financial risk. Your employer keeps that risk and pays TPAs a per-employee fee, typically $8 to $15 monthly per covered life.
This distinction matters enormously when your claim gets denied. If your employer uses a TPA instead of a traditional insurance carrier, the appeals process changes significantly, and state insurance regulations may not apply the same way.
What TPAs Actually Do
- Claim adjudication: TPAs review incoming claims against the plan's benefit language and coverage rules. They issue Explanations of Benefits (EOBs) that explain approval, denial, or reduction decisions.
- Prior authorization decisions: TPAs evaluate prior auth requests and determine whether planned procedures meet medical necessity criteria set by the plan.
- Internal appeals processing: When you dispute a denial, the TPA's appeals department reviews your case. Some TPAs use independent medical reviewers for appeals, others do not.
- Customer service: TPAs field calls about coverage, benefits, claims status, and appeals timelines.
- Claims data management: TPAs maintain records and generate reports for your employer.
How TPAs Affect Your Appeal Rights
The fact that a TPA handles your claim, rather than an insurance company, creates legal grey zones. Many states regulate insurance carriers directly but have weaker rules for self-funded plans managed by TPAs. This is because ERISA, the federal law governing employer benefit plans, preempts state insurance law for self-funded plans.
This means your appeal timelines, the quality of internal reviews, and your right to an external appeal may differ from what an insured plan would offer. Some states impose stricter rules on TPAs than others. Your first step should be reviewing your plan documents to identify who the TPA is and what your plan's appeal procedures actually say.
Internal appeals typically take 30 to 60 days. External appeals, when available, are handled by independent review organizations and take 30 to 72 hours for urgent requests and 30 days for standard reviews. Not all self-funded plans offer external appeals at all.
Red Flags in TPA Claims Processing
- Denials based on "lack of medical necessity" without clear reference to plan language or clinical guidelines.
- EOBs that do not cite the specific plan provision or reason for denial.
- Prior authorizations granted initially, then reversed after treatment is completed.
- Inconsistent application of the same coverage rule across similar claims.
- Missing documentation or failure to acknowledge receipt of your appeal within 5 business days.
Common Questions
Can a TPA make decisions differently than an insurance company would?
Yes. A TPA applies only the rules in your specific plan. An insurance company offers a standardized product across many employers. If your plan document lacks clear language on a coverage question, the TPA has discretion to interpret it. This is why reading your Summary of Benefits and Coverage matters before you submit a claim.
What happens if my TPA makes a mistake on a claim?
Request an internal appeal in writing. Cite the plan language that supports coverage and include clinical evidence if the denial cites medical necessity. If the TPA denies your appeal and your state allows external appeals for self-funded plans, pursue that next. Keep copies of everything, including the original EOB and your appeal letters.
Do I have rights if the TPA denies my prior authorization?
Yes, but the timeline matters. Appeal the denial before you have the procedure. Request an expedited appeal if the procedure is urgent. Do not assume a prior auth denial is final. Some TPAs overturn denials when presented with stronger clinical documentation or a corrected claim.
