What exactly can I ask for when I request my claim file?

More than the letter you already have. The federal claims rule defines four categories of 'relevant' document you are entitled to on request, free of charge: anything the plan relied on in denying you, anything submitted, considered, or generated during that decision whether or not it was relied on, anything showing the plan applied its rules consistently to similar claims, and, for group health and disability claims, any internal policy or guidance about the treatment or benefit tied to your diagnosis, again regardless of reliance (29 CFR 2560.503-1(h)(2)(iii) and (m)(8), read 19 August 2026). That reaches medical necessity criteria, reviewer notes, and prior-claim consistency records most people never think to ask for by name.

Does this right exist if my employer's plan is self-funded, or if I bought my plan on my own?

Yes, through two different doors. If your coverage is governed by ERISA, 29 CFR 2560.503-1(h)(2)(iii) applies directly. If it is not — a plan you bought yourself on the individual market, for instance — the same right is carried over by 45 CFR 147.136(b)(3)(ii)(C), which requires an issuer to let you review the claim file under the standards of 2560.503-1(h)(2). Employer group plans get the parallel version at 147.136(b)(2)(ii)(C), whether or not the plan is insured. The exception is a grandfathered plan, which this section generally does not reach (147.136(a)(1)(ii)). How to tell whether your plan is self-funded, and why that changes who else can help you, is covered separately.

Is there a deadline for the plan to send the documents, and does anything happen if it ignores the request?

The claim-file rule itself sets no day count — it says 'upon request,' not 'within X days.' A real 30-day clock with a dollar penalty attaches to a different, narrower request: the plan instruments, summary plan description, and annual report an ERISA plan administrator must furnish within 30 days of a written request under 29 U.S.C. 1024(b)(4), 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 (figure current as of the 2026 DOL inflation adjustment). For the claim-file request itself, the consequence of silence is different: a plan or issuer that fails to strictly adhere to the internal appeals rules, which includes this one, is treated as having exhausted its own process, and you may go straight to external review or court (45 CFR 147.136(b)(2)(ii)(F); the individual-market version is (b)(3)(ii)(F)).

Do I have to wait until I file my appeal to request the file?

No. Nothing in 29 CFR 2560.503-1(h)(2)(iii) ties the request to having an appeal already open, and asking earlier is usually the better sequence, because you want the documents in hand while you are still writing the appeal, not after. Some plans will not process the request until a claim number exists, which means an adverse benefit determination has already issued — but you do not need to have filed the appeal itself first.

Your Claim File Is Free: How to Request It, and From Whom

You wrote back after the denial and asked for "the file." What came back three weeks later was the same one-page letter you already had, mailed a second time. Nothing about which guideline the reviewer cited, whether a second person looked at the claim, or what your insurer's own medical policy says about the procedure it just refused to pay for.

That is not the plan being difficult. It is the plan answering a request that was too vague to force anything more specific out of it. There is a federal rule that names exactly what you are owed, in what condition, and at what cost, and citing it by paragraph number changes what comes back in the next envelope.

Everything below is checked against the eCFR text of 29 CFR 2560.503-1 and 45 CFR 147.136 as read on 19 August 2026, and every citation links to the paragraph it comes from. I am not a lawyer or a claims professional, so the point of the links is that you can open them and read the sentence yourself rather than take my summary of it.

The rule, in one sentence

A claimant has to be given, on request and free of charge, "reasonable access to, and copies of, all documents, records, and other information relevant to the claimant's claim for benefits" (29 CFR 2560.503-1(h)(2)(iii)). That sentence sits inside the "full and fair review" requirement, which is the standard every plan's appeal procedure has to meet to count as valid at all. A plan that will not produce relevant documents on request has not met it.

The word doing the real work is relevant, and the rule does not leave it to the plan's judgment. It is defined, and the definition is longer than most people expect.

What "relevant" actually reaches

Paragraph (m)(8) lists four ways a document can qualify, and only one of them requires that the plan actually used it:

Category	What it covers	Why it matters
(i) Relied upon	Anything the decision-maker actually used to deny you	The obvious one, and rarely the most useful
(ii) Submitted, considered, or generated	Anything that touched the file during the decision, whether or not it was relied on	Catches drafts, internal notes, and a reviewer's first pass before a supervisor changed the outcome
(iii) Compliance and consistency records	Anything showing the plan applied its rules the same way to similarly situated claimants, per the administrative safeguards required at (b)(5)	Lets you ask whether your denial matches how the plan treats everyone else's version of the same claim
(iv) Policy or guidance, group health and disability claims	Any internal statement of policy about the treatment or benefit tied to your diagnosis, regardless of reliance	Reaches the medical necessity criteria and clinical guidelines the plan owns even if the denial letter never quoted them

Read the four together and the shape of the right becomes clear. It is not "show me your work." It is "show me everything that touched this decision, plus everything you keep on file about people in my situation generally." Category (iv) is the one plans answer most reluctantly, because it reaches beyond your individual claim into the plan's general medical policy — the document a "not medically necessary" denial is usually built on but rarely quotes in full.

Who actually has this right

The regulation lives in Title 29, which is the ERISA title, so it is easy to assume the right belongs only to people with an employer plan. It does not — it reaches most people with employer or individual coverage, through two different doors.

Employer group health plans covered by ERISA get 29 CFR 2560.503-1(h)(2)(iii) directly. This is the large majority of job-based coverage, insured or self-funded.

Group health plans and issuers generally, ERISA or not, get the same standard carried over by the Affordable Care Act's claims rule. A group health plan or issuer must "allow a claimant to review the claim file," and must do so "in addition to complying with the requirements of 29 CFR 2560.503-1(h)(2)" (45 CFR 147.136(b)(2)(ii)(C)). This is the provision that reaches church plans and non-federal governmental plans, which sit outside ERISA but are still bound by this claims-file right through the ACA rule rather than through Title 29 directly.

Individual market plans — coverage you bought yourself, not through a job — get the same standard again, at 45 CFR 147.136(b)(3)(ii)(C), which cross-references the identical (h)(2) language. An issuer selling you a marketplace or off-marketplace individual policy owes you the claim file on the same terms as an employer plan owes it to a worker.

The exception is a grandfathered plan. Section 147.136 generally does not apply to grandfathered coverage, with a narrow carve-back for surprise-billing claims (147.136(a)(1)(ii)). If your plan card or SPD says "grandfathered," check whether your denial falls inside that carve-back before assuming this right applies to you the same way.

What this means in practice: whether you have the right does not turn on whether your plan is self-funded or fully insured. That fact changes something else entirely — which regulator can make your plan behave, and which external review process hears you if the internal appeal fails. If you have not confirmed which one your coverage is, that is worth doing before you go further; the guide to telling self-funded and fully insured plans apart walks through the one document that settles it.

The request, written two ways

Send it in writing, keep a copy, and note the date you sent it — that date matters later regardless of what comes back.

If your coverage is an ERISA employer plan, cite the claim-file rule and, separately, the broader plan-document rule that carries an actual penalty for silence:

Under 29 CFR 2560.503-1(h)(2)(iii) and (m)(8), please provide, free of charge, copies of all documents, records, and other information relevant to claim [number], including anything relied upon, anything submitted, considered, or generated in the course of the determination regardless of reliance, any record demonstrating consistent application of plan provisions to similarly situated claimants, and any internal policy or guidance concerning the denied treatment for my diagnosis. Separately, under 29 U.S.C. 1024(b)(4), please furnish the plan document, the latest summary plan description, and any insurance contract or other instrument under which the plan is established or operated.

The second sentence is not decoration. It pulls in a document set the claim-file rule does not reach — the underlying plan and insurance contract — and it is the one backed by the $110-a-day penalty described below.

If your coverage is a group or individual market plan and you are not sure it is ERISA-governed, or you know it is not, cite the ACA provision instead:

Under 45 CFR 147.136(b)(2)(ii)(C) [use (b)(3)(ii)(C) for an individual market plan] and 29 CFR 2560.503-1(h)(2)(iii) and (m)(8), please allow me to review the claim file for claim [number] and provide, free of charge, copies of all documents, records, and other information relevant to the claim, including any internal policy or guidance concerning the denied treatment for my diagnosis.

Send either version to the appeals address printed on the denial notice, not to the general customer service line — a request routed through a call center is the version most likely to come back as a second copy of the letter you already have.

The clock most people assume exists, and does not

Search the claim-file rule for a deadline and you will not find one. Paragraph (h)(2)(iii) says "upon request," full stop — no ten days, no thirty. That surprises people who have heard that ERISA carries a firm production deadline, and the confusion is understandable, because a real one does exist. It just attaches to a narrower, different request.

29 U.S.C. 1024(b)(4) requires a plan administrator to furnish the plan instrument, the latest SPD, and the latest annual report within 30 days of a written request. Miss that window and a court may, at its discretion, hold the administrator personally liable for up to $110 a day from the 31st day until the documents show up (29 U.S.C. 1132(c)(1), the dollar figure set by 29 CFR 2575.502c-1 under the 2026 inflation adjustment). That penalty is real, but it only reaches the document set named in 1024(b)(4) — the plan and its governing instruments — not the claim-specific file covered by (h)(2)(iii). It also only exists for ERISA plans; there is no equivalent per-day fine sitting behind an individual-market or non-ERISA claim-file request.

So two different letters produce two different kinds of pressure. The plan-document request under 1024(b)(4) has teeth with a dollar sign on them. The claim-file request under (h)(2)(iii) has a different kind of leverage: a plan or issuer that fails to comply with the full-and-fair-review requirements, and this is one of them, is treated as having exhausted its own internal process on your claim. You are not stuck waiting for round two — you may go straight to external review or to court (45 CFR 147.136(b)(2)(ii)(F) for group plans, (b)(3)(ii)(F) for individual market issuers). That is not a fine the plan pays you. It is a door out of an internal process that has stopped functioning, and for most people it is worth more than $110 a day would be.

There is a narrow limit on that leverage worth knowing before you rely on it: a violation that is minor, non-prejudicial, made in good faith, and not part of a pattern does not trigger deemed exhaustion (147.136(b)(2)(ii)(F)(2)). One slow response to a claim-file request, on its own, may not clear that bar. A flat refusal, or silence through your entire appeal window, generally will.

Reading what comes back

The documents you get are only useful if you actually check them against your denial letter. Three things worth confirming when the envelope arrives:

Does the cited guideline actually match your diagnosis and procedure, or a nearby one the plan applied by analogy. Insurers sometimes deny under a policy written for a related but distinct condition.
Is there a second reviewer's name anywhere, and does their note say something different from the final letter. A gap between an internal recommendation and the outcome you received is worth raising by name in the appeal.
Does anything in category (iii) — the consistency records — show a claim like yours being paid elsewhere in the file. Plans are not required to volunteer this, but if it surfaces once you have the documents, it belongs in your appeal letter.

None of this substitutes for reading your denial letter itself first, in the order that actually tells you what happened — that walk-through is a useful companion to this one before you decide what to request. And this is a different document from the itemized hospital bill you may also be chasing down: the itemized bill tells you what the provider charged; the claim file tells you why the insurer refused to pay for it.

The paragraph worth sending today, before anything else, is one of the two letters above, addressed to the appeals address on your notice, with the claim number filled in and a copy kept with the date you sent it. Everything you put in the actual appeal comes out of what that letter gets back.

If a citation here has moved since 19 August 2026, or your insurer's response contradicts what these paragraphs say, tell me and I will check it. More on how these pages are sourced is on the about page.
