Fiduciary Oversight Is More Than an Add-On

TABLE OF CONTENTS

Fiduciary oversight becomes a core service, not an add-on, when brokers provide it as an ongoing service with clear deliverables, such as regular claims reviews, documented TPA performance checks and reports prepared for fiduciary committees. This turns a responsibility plan sponsors already have under ERISA Section 404 into a defined, recurring and billable service.

A mid-size manufacturer with 340 covered employees discovered that its TPA had been using the wrong payment rate for out-of-network claims for 18 months. The error was found only after a new CFO ordered an independent claims audit before renewal. The audit helped the plan recover nearly $210,000. The broker had never provided ongoing oversight beyond mentioning it in the annual stewardship presentation.

This happens every year across the self-funded health plan market. It shows why fiduciary oversight is often treated as a free courtesy instead of a separate service that can provide real financial value.

Willis Towers Watson research shows that administrator errors typically affect 1% to 3% of total claims, while financial accuracy errors can be around 1% of paid claims, even when administrators meet industry standards.

For a plan spending $20 million a year, even a 1% error rate could mean $200,000 in potential overpayments or errors that go unnoticed.

Key Takeaways

Fiduciary oversight is a legal duty: ERISA Section 404 makes fiduciary oversight a legal responsibility, not a courtesy line item. Treating it as optional can leave plan sponsors exposed while undervaluing the work brokers perform.

Enforcement is intensifying: DOL/EBSA recovered more than $1.4 billion for benefit plans in FY 2025 across 878 closed civil investigations, signaling continued enforcement attention on health and welfare plans.

Claims errors create real exposure: Administrator error rates commonly range from 1% to 3% of total claims, while independent reviews can identify higher error rates when the full claims population is examined instead of a sample.

Make oversight a defined service: Treat fiduciary oversight as a core offering with clear deliverables, a defined review cadence and separate pricing rather than bundling it into annual renewal work.

Documentation is part of the value: Plan sponsors that treat oversight as an ongoing service can build the documented record needed to demonstrate the prudent expert standard under ERISA Section 404.

Bottom line: Fiduciary oversight should be structured, documented and priced as a core service. It protects the plan sponsor while giving brokers a clear way to demonstrate and monetize the value of ongoing oversight.

What "Positioning Fiduciary Oversight as a Core Service" Actually Means

Positioning fiduciary oversight as a core service means clearly defining it, explaining what it includes and charging for it separately instead of burying it in a renewal presentation. Most brokers already do parts of this work: they review claims trends, flag stop-loss issues or mention TPA performance guarantees. But these actions alone do not create documented, ongoing oversight or give the plan sponsor evidence of a prudent process if the DOL asks for it.

The common assumption is that TPAs handle accuracy internally and that a broker's job ends at plan design and carrier negotiation. The reality is that ERISA places the fiduciary burden on the plan sponsor, not the administrator, for every dollar the plan pays out. A TPA's self-reported accuracy rate is not oversight. It is the vendor grading its own homework.

Why Fiduciary Oversight Keeps Getting Treated as an Add-On

The root cause is structural, not a lack of awareness. Broker compensation has historically been tied to placement and renewal, so revenue flows from the sale, not from ongoing monitoring, and monitoring gets deprioritized by default.

A second root cause is capability. Genuine claims oversight requires access to raw claims data, analytics tools and clinical or coding expertise that a generalist broker team was never built around, so the work gets waved off as "the TPA's job" rather than built out as a service.

A third factor is inertia inside plan sponsor organizations. HR and finance leaders assume that because a TPA is contractually obligated to pay claims correctly, someone is already checking that they do. Baker Tilly notes it is common for organizations to perform a claim audit only once every three years, which leaves long windows where nothing is being verified at all.

The Real Cost of Leaving Oversight Unpriced

Unreviewed claims dollars do not disappear. They compound, and the compounding is the real cost most plan sponsors never see on a single line item.

An independent claims analytics firm's client data across a large self-funded book found 5% to 15% error detection rates once claims were fully reviewed, with average findings landing between $500 and $1,200 per employee per year.

A peer-reviewed study found that sample-based claims audits can miss significant errors. In two Fortune 100 companies, random sampling failed to detect errors worth $200,000 to $750,000 because only a portion of claims were reviewed. The takeaway is simple: a small sample can leave significant dollars undetected.

What's Actually Happening Behind the Scenes

TPA Sampling Covers a Sliver of the Plan

Standard TPA-conducted audits typically review a stratified sample of a few hundred claims out of tens of thousands processed annually, then extrapolate an accuracy score from that sample. The extrapolation looks clean on a stewardship slide, but it was never designed to catch every category of error, only the categories most likely to show up in a small, structured sample.

Financial Accuracy Is Not the Same as Payment Accuracy

A plan can hit its financial accuracy target, meaning the dollar amount paid was close to correct, while still failing payment accuracy, meaning the claim was processed against the wrong plan rule, provider contract or coordination of benefits determination entirely. Baker Tilly's audit example showed exactly this split, with financial and payment accuracy landing at different rates against the same set of claims.

Broker Compensation Structures Rarely Reward Vigilance

The CAA 2021 rules require brokers and consultants to disclose how they are compensated, giving plan sponsors more visibility into broker fees. But compensation tied to placing or renewing coverage does not necessarily reflect the time spent on ongoing claims and TPA oversight. This gives brokers an opportunity to clearly define fiduciary oversight as a separate service and charge for the work they perform.

Why Current Approaches Aren't Enough

Most plans default to whatever oversight the TPA offers as part of the base contract, and that default carries structural conflicts that a standalone, independently priced oversight engagement does not.

Dimension	Status Quo (TPA Self-Audit, Bundled)	Fiduciary Oversight as a Core Service
Who Performs the Review	The TPA reviews its own claims processing	An independent party reviews the TPA's work
Claims Reviewed	A stratified sample, often a few hundred claims	Full-population or near-full review using automated tools
Reporting Cadence	Annual or once every few years	Quarterly or ongoing, matched to committee meetings
Documentation Produced	Summary accuracy percentage	Committee-ready findings tied to specific plan provisions
Conflict of Interest	The reviewer and the reviewed are the same entity	Independent of the TPA relationship
Pricing Model	Bundled into administrative fees	Priced and scoped as its own line item
Fiduciary Protection	Limited documented process to point to	Builds the paper trail ERISA Section 404 expects

How to Fix It: A Framework for Positioning Oversight as a Core Service

Name the Service Explicitly

Give it a defined title in every proposal and renewal deck, such as "Fiduciary Oversight Program," rather than folding it into "stewardship" or "renewal support."

Scope Concrete Deliverables

Specify claims sampling frequency, TPA performance benchmarking against the service level agreement and a documented findings report that the committee actually receives.

Set an Independent Cadence

Schedule quarterly reviews tied to plan committee meetings. This creates a recurring touchpoint that demonstrates value and generates the documentation regulators look for.

Price It Apart From Placement

Use a retainer or per-employee-per-month fee separate from commission or renewal compensation. This reduces conflicts of interest and makes the cost and value of the work clear.

Use CAA Disclosure as an Opening

Since brokers must already disclose compensation over $1,000 under the CAA 2021 rule, use that conversation to introduce fiduciary oversight as a distinct and transparently priced service.

Document Everything in Writing

Maintain committee minutes, findings memos and corrective action logs. These records form the evidence supporting a prudent expert standard defense and only exist when someone produces them on a defined schedule.

Report Findings in Dollars, Not Just Percentages

An error rate means little to a CFO. Show the recovered or avoided dollar amount and tie it to a specific claims category. That is what demonstrates the financial value of the service.

Red Flags That Signal Your Plan Needs This Now

Our last claims audit was performed by the same TPA whose claims were being audited.

Nobody on your benefits committee can name the date of the last independent claims review.

Your broker's stewardship report shows trend and renewal numbers but no claims accuracy findings.

Your plan has never seen a full-population claims review, only sample-based audits.

You cannot produce a written record showing how your organization selected and monitored its TPA.

Your stop-loss carrier has flagged high-dollar claims that were never independently verified before payment.

Nobody has confirmed that your broker's CAA 2021 compensation disclosure was received and reviewed.

The ROI of Doing It Right

Independent claims reviews can uncover far more money than they cost. ClaimInformatics client data shows 5% to 15% error detection rates in full-population reviews, with average findings of $500 to $1,200 per employee per year. For a 500-employee plan, even the low end could mean $250,000 in findings that a sample-based audit might have missed.

The value goes beyond recovering money. A documented, ongoing oversight process gives plan sponsors evidence that they are actively monitoring their plan if the DOL asks questions. EBSA's FY 2025 enforcement activity shows why this matters. The agency closed 878 civil investigations, with 556 resulting in repayments or corrective action, and recovered more than $1.4 billion for benefit plans overall.

Making fiduciary oversight a defined, paid service helps brokers deliver measurable value while giving plan sponsors a stronger record of prudent oversight.

Conclusion and Next Steps

Fiduciary oversight was never meant to be a courtesy add-on to a broker renewal. It is a standing legal obligation under ERISA Section 404, and the plans that treat it as core, priced and documented are the ones building a real defense against both financial leakage and regulatory exposure. Positioning it that way is also the clearest path for brokers and consultants to build a recurring, defensible revenue line instead of competing on placement alone.

Start with one step: pull your plan's last claims audit and ask who performed it, what percentage of claims it actually reviewed and what happened to the findings. If you cannot answer all three, fiduciary oversight is still an add-on in your organization, not a core service.

Frequently Asked Questions

What does "fiduciary oversight as a core service" mean?

‍It means naming, scoping and pricing claims and TPA oversight as its own engagement rather than bundling it free into a broker or consulting contract.

Is fiduciary oversight legally required under ERISA?

‍Yes. ERISA Section 404 requires plan fiduciaries to act as a prudent expert would in monitoring how plan assets, including claims payments, are handled.

How is fiduciary oversight different from a standard TPA claims audit?

‍A TPA audit reviews the TPA's own work using a small claims sample. Independent oversight reviews the TPA using outside tools and a much larger claims population.

How often should a self-funded plan review its TPA's claims accuracy?

‍Quarterly reviews aligned to benefits committee meetings build a stronger, more defensible record than the once-every-few-years cadence many plans currently use.

What is a typical TPA claims error rate?

‍Industry sources place standard error rates around 1% to 3% of total claims, with some independent full-population reviews finding 5% to 15% error detection rates.

Can brokers charge separately for fiduciary oversight services?

‍Yes, and the CAA 2021 compensation disclosure rule makes that separate pricing more transparent, not less viable, since compensation must already be disclosed.

What documentation proves a plan sponsor met its fiduciary duty?

‍Committee meeting minutes, written TPA performance reviews, claims audit findings and corrective action logs together form the paper trail regulators expect to see.

What happens if a self-funded plan skips independent oversight entirely?

‍The plan sponsor carries undocumented fiduciary exposure, and EBSA's FY 2025 enforcement data shows regulators are actively pursuing exactly these gaps in health and welfare plans.
