Key Takeaways
- The Summary Plan Description (SPD) is the legally binding document that governs what your plan covers, what it excludes, and how disputes are resolved — it is not a marketing brochure.
- Vague or outdated SPD language is one of the most common sources of claims disputes, member complaints, and ERISA litigation.
- The plan document and the SPD must be consistent — when they conflict, courts typically rule in favor of the member.
- Exclusions and limitations must be clearly and specifically written — ambiguous exclusions are often unenforceable.
- Every self-funded employer should review their SPD annually and update it to reflect plan changes, regulatory requirements, and lessons from claims disputes.
What the SPD Is and Why It Matters
The Summary Plan Description is the document that tells plan participants — your employees and their dependents — what the health plan covers, what it excludes, how to file claims, how to appeal denials, and what their rights are under ERISA. It is required by law for every ERISA-governed health plan, and it must be written in a manner calculated to be understood by the average plan participant.
For self-funded employers, the SPD is also the primary legal document governing the plan's financial obligations. When a claim is disputed, the SPD language is what courts and arbitrators look to first. Vague, inconsistent, or outdated SPD language is a significant legal and financial liability.
The SPD is not a summary of the plan — for most self-funded employers, it IS the plan. Unlike fully-insured plans where the insurance contract is the governing document, self-funded plans are governed by the plan document and SPD. If your SPD says something is covered, you are legally obligated to cover it, even if you intended otherwise.
Many self-funded employers are using SPDs that were drafted years ago and never updated to reflect plan changes, new cost-containment programs, or regulatory requirements. An outdated SPD creates coverage obligations you may not have intended and exclusions that may not be enforceable. Annual SPD review is not optional — it is an ERISA fiduciary obligation.
ERISA requires that the SPD be provided to new participants within 90 days of becoming covered and to all participants every 5 years if the plan has been amended, or every 10 years if it has not. Most employers are not meeting this requirement. Document your SPD distribution and keep records of when each participant received it.
The Plan Document vs. the SPD
Many self-funded plans have two documents: a formal plan document (sometimes called the plan instrument or wrap document) and the SPD. The plan document is the master legal instrument; the SPD is the participant-facing summary. When these two documents conflict, the legal outcome depends on the jurisdiction — but courts frequently rule in favor of the participant when the SPD is more generous than the plan document.
- The plan document governs the employer's internal administration and fiduciary obligations.
- The SPD governs what participants are entitled to — and what they were told they were entitled to.
- When the SPD is more generous than the plan document, participants can often enforce the SPD terms.
- When the plan document is more generous than the SPD, the employer may be bound by the plan document.
- The safest approach: keep the plan document and SPD consistent and update both simultaneously when the plan changes.
A common and expensive mistake: the employer amends the plan document to add a new exclusion or limitation but forgets to update the SPD. A participant who relies on the old SPD language to make a healthcare decision — and then has the claim denied under the new plan document — has a strong legal argument that the employer is bound by the SPD they were given.
Summary of Material Modifications (SMM): whenever you make a material change to the plan, ERISA requires you to provide participants with an SMM within 210 days after the end of the plan year in which the change was adopted — or 60 days if the change reduces benefits. Most employers do not know this requirement exists.
Exclusions and Limitations: Getting the Language Right
Exclusions are the provisions that define what the plan does not cover. Limitations are provisions that restrict coverage — dollar limits, day limits, visit limits, or prior authorization requirements. Both must be written with precision. Ambiguous exclusion language is one of the most common sources of claims disputes and one of the most frequently litigated areas of ERISA health plan law.
- Experimental and investigational exclusions: must define specifically what qualifies as experimental — vague language is frequently challenged.
- Medical necessity requirements: must define who determines medical necessity and what the standard is.
- Prior authorization requirements: must specify which services require prior authorization and the consequences of not obtaining it.
- Out-of-network limitations: must clearly state how out-of-network claims are priced and what the member's cost-sharing is.
- Coordination of benefits: must specify how the plan coordinates with other coverage the member may have.
The experimental and investigational exclusion is one of the most litigated provisions in health plan law. Courts have consistently held that vague language — "treatments not generally accepted by the medical community" — is insufficient. Your SPD should define experimental and investigational by reference to specific criteria: FDA approval status, clinical trial phase, coverage decisions by Medicare or major commercial carriers, and peer-reviewed medical literature.
Prior authorization requirements that are not clearly disclosed in the SPD are often unenforceable. If your plan denies a claim because the member did not obtain prior authorization, but the SPD does not clearly state that prior authorization is required for that service, you may be obligated to pay the claim. Audit your prior authorization requirements against your SPD language annually.
The Mental Health Parity and Addiction Equity Act (MHPAEA) requires that mental health and substance use disorder benefits not be subject to more restrictive limitations than medical and surgical benefits. Prior authorization requirements, visit limits, and medical necessity criteria for behavioral health must be comparable to those for medical benefits. Non-quantitative treatment limitations (NQTLs) are a major compliance focus — your SPD language must reflect parity.
Claims and Appeals Language
ERISA and ACA regulations impose specific requirements on how health plans must handle claims and appeals. The SPD must describe the claims and appeals process in detail — and the plan must follow that process exactly. Failure to follow the SPD's claims and appeals procedures can result in the member being deemed to have exhausted administrative remedies and being entitled to sue in federal court.
- Initial claim decision: urgent care claims within 72 hours; pre-service claims within 15 days; post-service claims within 30 days.
- First-level appeal: urgent care within 72 hours; pre-service within 30 days; post-service within 60 days.
- External review: members must have access to independent external review for adverse benefit determinations.
- Notice requirements: denial notices must include the specific reason for denial, the plan provision relied upon, and instructions for appealing.
- Full and fair review: on appeal, the plan must provide the member with all documents relied upon in the denial decision.
The external review requirement is one of the most important — and most commonly violated — ACA provisions for self-funded plans. Members have the right to an independent external review of adverse benefit determinations. If your SPD does not describe the external review process, or if your plan does not have an external review process in place, you are out of compliance.
Build a claims and appeals tracking system — even a simple spreadsheet — that logs every denial, every appeal, and every outcome. This serves two purposes: it helps you identify patterns in denials that may indicate SPD language problems, and it creates a compliance record that demonstrates your plan is following its own procedures.
Annual SPD Review Checklist
Every self-funded employer should conduct an annual SPD review before the plan year begins. This review should address regulatory changes, plan design changes, lessons from the prior year's claims disputes, and any new cost-containment programs being implemented.
- Confirm the SPD reflects all plan design changes made during the prior year.
- Review all exclusions and limitations for clarity and enforceability.
- Verify prior authorization requirements are clearly disclosed for all services that require it.
- Confirm the claims and appeals process meets current regulatory requirements.
- Check that the external review process is described and operational.
- Verify MHPAEA parity — mental health and substance use disorder limitations are not more restrictive than medical/surgical.
- Confirm the SPD has been distributed to all participants and new hires within required timeframes.
- Issue a Summary of Material Modifications for any changes made during the prior year.
The annual SPD review is an ERISA fiduciary obligation — not a nice-to-have. As plan sponsor, you are personally liable for fiduciary breaches. An SPD that is outdated, inconsistent with the plan document, or that fails to disclose required information is a fiduciary breach waiting to be discovered. Document your annual review process and keep records.
Engage an ERISA attorney to review your SPD at least every 3 years — and whenever you make significant plan design changes. The cost of a legal review ($1,500 to $3,000) is trivial compared to the cost of defending a claims dispute or DOL audit that traces back to deficient SPD language.
Your Action Steps
- 1Pull your current SPD and plan document — confirm they are consistent and that the SPD reflects your current plan design.
- 2Identify the date your SPD was last updated and compare it to any plan changes made since that date.
- 3Review your experimental and investigational exclusion — does it define the standard by reference to specific criteria?
- 4Audit your prior authorization requirements — are all services requiring prior authorization clearly disclosed in the SPD?
- 5Verify your claims and appeals process meets current regulatory timeframes and includes an external review option.
- 6Schedule an annual SPD review with your TPA and ERISA counsel before each plan year begins.
