SPD vs SBC: Which Plan Document Governs

Somewhere in the denial there is a phrase like not a covered benefit under the terms of the Plan, followed by a section number, followed by nothing. No quotation. No document title. No page. And the only coverage paper in your house is the four-page grid from open enrollment, the SBC, which lists that service as covered at 20% coinsurance after the deductible.

Two pieces of paper about the same coverage, saying opposite things. This comes up constantly, and the reason is structural rather than sinister: American health coverage runs on a stack of documents written by different people, under different rules, for different purposes, and only one layer of the stack is a contract.

Sorting out which layer you are holding is the whole job here. It changes what you quote in the appeal, what you demand in writing, and which agency has anything to say about it.

Each citation below links to the paragraph it came from. The eCFR prints a currency date at the top of every section it serves, and the one dollar figure on this page carries the Federal Register citation for the amendment that set it, so both can be re-checked against something dated instead of taken on trust. Nothing here is legal advice, and nothing here is an opinion about your treatment — this is a page about which sheet of paper carries the terms.

What each of the four papers is for, and who wrote it

Yes, four. Most people are handed three names and never learn that a fourth document sits underneath all of them.

Document Who produces it The rule that requires it What it looks like
Plan document, and the insurance policy if there is one The plan sponsor, usually your employer 29 U.S.C. 1102(a)(1) — every plan "shall be established and maintained pursuant to a written instrument" Unbound, unbranded, no page limit, occasionally hundreds of pages
SPD, the summary plan description The plan administrator 29 CFR 2520.102-3 A booklet, ending in a statement of ERISA rights
EOC or certificate of coverage The insurance issuer, or the Medicare Advantage organization State form filing; for MA, 42 CFR 422.111 Carrier-branded, contract voice, defined terms in capitals
SBC, the summary of benefits and coverage The plan and the issuer 45 CFR 147.200 Four double-sided pages, nothing smaller than 12-point

The SBC is the one nearly everyone has, because it arrives with enrollment materials and it is short enough to keep. It is also the one that removes itself from this argument in writing. Among the items every SBC must contain is:

A statement that the SBC is only a summary and that the plan document, policy, certificate, or contract of insurance should be consulted to determine the governing contractual provisions of the coverage.

— 45 CFR 147.200(a)(2)(i)(H)

Find that sentence on your own SBC. It is usually in small print at the top of page one or the bottom of the last page, and it is not boilerplate the carrier chose to add. A federal rule put it there.

The 2011 decision that settles the SPD question

For decades, plenty of federal courts applied a rough rule: where the SPD and the plan document conflict, the SPD wins, because participants read the summary and not the instrument. It was repeated widely enough that HR staff still say it.

The Supreme Court took it apart in CIGNA Corp. v. Amara, 563 U.S. 421 (2011). CIGNA had converted a pension plan and described the conversion in summaries the district court found misleading; the district court then reformed the plan and ordered benefits paid under the rewritten terms, resting on ERISA section 502(a)(1)(B), the provision that lets you sue to recover benefits due under the terms of your plan. The Court said that section could not carry the weight:

[W]e conclude that the summary documents, important as they are, provide communication with beneficiaries about the plan, but that their statements do not themselves constitute the terms of the plan for purposes of §502(a)(1)(B).

— CIGNA Corp. v. Amara, opinion of the Court

The reasoning is about who does what. The sponsor creates the plan's basic terms and executes the written instrument containing them. The administrator, a separate role even when the same company fills both, manages the plan and hands out documents describing it. A description of a contract, the Court said, is not the contract, any more than a summary of a deed is the deed.

So when the two disagree about what the coverage is, the written instrument carries the contractual terms. That is the short answer, and it is why the first move is to stop arguing from the booklet and go get the instrument.

Why the summary still has teeth

None of which makes the SPD decorative. Amara went on to hold that relief was available under a neighboring provision, section 502(a)(3), which authorizes "appropriate equitable relief" — and the Court walked through three traditional equitable remedies that fit: reformation of the plan's terms to correct false or misleading information, estoppel to hold the sponsor to what it had promised, and surcharge, a monetary remedy against a fiduciary. On proof, the Court was specific that surcharge requires "actual harm" shown by a preponderance of the evidence, and that actual harm "may sometimes consist of detrimental reliance, but it might also come from the loss of a right protected by ERISA."

The disclosure rules the SPD has to satisfy are stricter than most people assume, which is what makes a contradiction worth documenting rather than shrugging at. The format rule is blunt about it: any description of exceptions, limitations, reductions and other restrictions "shall not be minimized, rendered obscure or otherwise made to appear unimportant," and must be summarized in a manner "not less prominent than the style, captions, printing type, and prominence used to describe or summarize plan benefits" (29 CFR 2520.102-2(b)). The contents rule sits beside it and opens by requiring that the SPD "accurately reflect the contents of the plans" (29 CFR 2520.102-3). An exclusion buried in the plan document and absent from the SPD's list of exclusions is not merely awkward for the plan. It is a compliance problem with a name.

The common misstep at this stage is quoting the SBC in the appeal letter, simply because the SBC is the document within reach. It is not a wasted paragraph, but it is the weakest one you will write, and a reviewer who knows the rules will answer it with the disclaimer printed on the SBC itself. Quote the SBC as evidence of what the plan told you, then move straight to the language you are about to go get.

Making the plan name the provision it denied you under

You are entitled to have the provision identified before you argue about it. Every notice of adverse benefit determination must set out "[r]eference to the specific plan provisions on which the determination is based" (29 CFR 2560.503-1(g)(1)(ii)). For group health coverage there is more: the reason for the determination must include the denial code and its corresponding meaning, plus a description of the plan's or issuer's standard, if any, that was used in denying the claim (45 CFR 147.136(b)(2)(ii)(E)(3)). A letter that hands you a bare section number has arguably not met the second requirement, and saying so is a legitimate line in an appeal.

Then request the document itself. The request that reaches the instrument is the one under ERISA section 104(b)(4), 29 U.S.C. 1024(b)(4), which obliges the plan administrator to furnish, on written request, the latest SPD, the latest annual report, and "the bargaining agreement, trust agreement, contract, or other instruments under which the plan is established or operated." That last clause is the one to copy word for word — it is what reaches the plan document, the wrap, and the insurance policy or certificate. The 30-day clock and the $110-a-day penalty sitting behind it are laid out in the self-funded or fully insured walkthrough, and the same letter is a sensible place to also invoke your separate right to the claim file, free of charge.

Two details separate a useful answer from another booklet. Put the date of service in the letter and ask for the version in effect on that date: plans amend, and a 2026 document answers a 2026 question your claim may not be asking. Then quote the section number the denial letter cited and ask which page it appears on, which turns a vague document request into one a benefits administrator can fill without first deciding what you meant.

Insured coverage puts the EOC in the middle of the stack

If your employer bought a policy, or you bought coverage yourself, the evidence of coverage — sold also under the names certificate of coverage, certificate of insurance, or policy — is part of the contract, and a state insurance department reviewed the form before it could be issued. That is a genuinely different animal from a summary. It is frequently also your SPD, or half of it: many employers meet the SPD obligation by distributing the carrier's certificate together with a short wrap document supplying the pieces ERISA requires that a carrier form does not carry.

Which is how you can tell what is in your hands. An SPD has to include the plan's name and number, the plan administrator's name and address, the agent for service of legal process, the funding medium (29 CFR 2520.102-3(q)), the claims procedures at paragraph (s), and a consolidated statement of ERISA rights at paragraph (t). A booklet with defined terms, exclusions and a carrier logo but none of those items reads as a certificate rather than as a complete SPD. That is an inference from the contents list, not a DOL ruling about carrier certificates as a class, so put it to the administrator as a question: which document, or combination of documents, is the plan treating as the SPD?

On the individual market there is a shortcut. Issuers must print on the SBC "an Internet web address where a copy of the actual individual coverage policy or group certificate of coverage can be reviewed and obtained" (45 CFR 147.200(a)(2)(i)(J)). And an SBC itself must be provided on request as soon as practicable, and in no event later than seven business days (147.200(a)(1)(ii)(F)) — a faster clock than anything in the ERISA disclosure rules, and worth using when what you actually want is that web address rather than the grid.

Medicare Advantage runs on a separate shelf

If your card says Medicare Advantage, most of the above changes shape. The SBC requirement does not reach a group health plan benefit package providing MA benefits at all (45 CFR 147.200(f)). In its place, the MA organization must disclose a detailed description of benefits, conditions, limitations and cost sharing "[a]t the time of enrollment and at least annually thereafter, by the first day of the annual coordinated election period" (42 CFR 422.111(a)(3)), and must maintain a website carrying copies of its evidence of coverage, at 422.111(h)(2)(ii).

That posting requirement is the practical one. The EOC for your plan can often be pulled off the organization's website without asking a human being, which is unlike almost every other document on this page. Pull the year that matches your date of service, not the current one. If only the current year is posted, the same paragraph adds that posting "does not relieve the MA organization of its responsibility under paragraph (a) of this section to provide hard copies to enrollees upon request" — so ask for the contract year you need, in writing. The appeal it feeds into runs on its own timetable, mapped out in the five levels of a Medicare appeal.

When the summary is not wrong, only behind

A third possibility deserves its own look, because it explains a lot of conflicts that look like contradictions: the SPD was accurate when it was printed, and the plan changed afterward.

The rules leave real gaps here. An SPD need only reflect the plan's contents "as of the date not earlier than 120 days prior to the date such summary plan description is disclosed" — the opening sentence of 29 CFR 2520.102-3, before the contents list even begins. A summary of material modifications is generally due within 210 days after the close of the plan year in which the change was adopted (29 CFR 2520.104b-3(a)) — which, for a calendar-year plan, means a change adopted in February can legitimately reach you the following July. Group health plans get a tighter rule for the changes that hurt: a material reduction in covered services or benefits must be summarized within 60 days after adoption, at paragraph (d)(1), unless the plan communicates with participants at regular intervals of no more than 90 days, in which case paragraph (d)(2) applies instead. A full updated SPD comes around every five years when the plan has been amended, and every ten years when it has not (2520.104b-2(b)).

On the SBC side the timing runs the other way. A material modification affecting SBC content that happens outside a renewal requires 60 days' advance notice before it takes effect (45 CFR 147.200(b)). Mid-year changes are meant to reach you before they bite, not after.

So the request is never just "the SPD." It is the SPD and every summary of material modifications issued since it was printed. A copy furnished under the regulations is required to be accompanied by all SMMs not yet incorporated into it, at 2520.104b-3(c). Ask for them by that name and the gap closes.

Where the paperwork question turns into a different kind of question

There is a boundary to what reading documents can do for you, and it is worth knowing where it sits before you spend another month on letters.

If the plan produces the instrument and the exclusion is genuinely in there, clearly worded, and the SPD said the same thing, the document fight is over and the argument moves to medical necessity or to coding. If the plan will not produce the instrument at all, that is an enforcement question, and for an ERISA plan it goes to the Department of Labor's Employee Benefits Security Administration, whose benefits advisors take it at 1-866-444-3272 or through askebsa.dol.gov. If the instrument and the summary say different things and the difference cost you money, the remedies Amara describes — reformation, estoppel, surcharge — are things courts order, not things you can invoke by letter, and that is the point at which a call to an ERISA attorney stops being premature.

Enforcement of the SBC rule sits somewhere else again, which tends to surprise people. A health insurance issuer or a non-federal governmental plan that willfully fails to provide required SBC information faces a fine of "not more than $1,000 as adjusted annually under 45 CFR part 102 for each such failure," with each covered individual counting as a separate offense (45 CFR 147.200(e)). The adjusted figure lives in the table at 45 CFR 102.3, where the row for 147.200(e) reads $1,443 in the version of that table amended on 28 January 2026 by HHS's annual adjustment rule (91 FR 3665, with the part 102 amendment at 3666) — the 2025 adjustment, published late, and applicable to penalties assessed on or after that date. The table is rewritten every year, so read that row rather than carrying the number around. Private ERISA plans are not on that list; they answer to the Labor Department instead. Which desk your complaint belongs on therefore turns on the same funding question that decides so much else about your coverage.

The thing worth doing this week is narrow. Write the section 104(b)(4) request, put in it the exact section number your denial letter cited and the date of service, and ask for the instrument in effect on that date plus every SMM since. Everything above is a way of deciding what to compare it against once it lands. Regulations get amended and court doctrine gets refined, so open each linked paragraph and check its currency date against the date at the top of this page before you rely on it.

Frequently asked questions

My SBC says the service is covered but the denial says it is excluded. Does the SBC win?

No, and the SBC says so about itself. Federal rules require every SBC to carry a statement that it is only a summary and that the plan document, policy, certificate, or contract of insurance should be consulted to determine the governing contractual provisions of the coverage (45 CFR 147.200(a)(2)(i)(H)). A conflict between the SBC and the denial is still worth raising, because it shows the plan's own summary described the benefit differently. But the enforceable terms sit in the plan document or policy, not in the four-page summary.

I was told for years that the SPD controls when it conflicts with the plan document. Is that wrong?

That shortcut stopped working in 2011. In CIGNA Corp. v. Amara, 563 U.S. 421, the Supreme Court held that summary documents provide communication with beneficiaries about the plan, but that their statements do not themselves constitute the terms of the plan for purposes of ERISA section 502(a)(1)(B) — the claim-for-benefits provision. The Court then pointed to section 502(a)(3), which lets a court order equitable relief such as reformation, estoppel, or surcharge where a summary was false or misleading. So a misleading SPD is still actionable; it just travels a different road than 'the SPD wins.'

How do I get the actual plan document, not another copy of the booklet?

Ask the plan administrator in writing for 'the instruments under which the plan is established or operated,' which is the statutory phrase in ERISA section 104(b)(4), 29 U.S.C. 1024(b)(4). That reaches the plan document itself, any wrap document, and the insurance policy or certificate. Name the section number the denial letter cited and the date of service, so the administrator has to produce the version in effect then rather than the current one. The administrator has 30 days, backed by a court-discretionary penalty of up to $110 a day under 29 U.S.C. 1132(c)(1) and 29 CFR 2575.502c-1.

My SPD is from three years ago. Is it still the operative summary?

Possibly, and that is why you should ask for the amendments separately. A plan generally has until 210 days after the close of the plan year in which a change was adopted to furnish a summary of material modifications (29 CFR 2520.104b-3(a)), but a group health plan has only 60 days after adoption for a material reduction in covered services or benefits (2520.104b-3(d)(1), subject to a 90-day alternative for plans that communicate at regular intervals). A full updated SPD is required only every five years when the plan has been amended, and every ten years otherwise (29 CFR 2520.104b-2(b)). Request the SPD and every SMM issued since it was printed.
