ERISA claim file request letter: what operators need to know
A downloadable letter that asks an employer-sponsored plan for the documents it relied on, citing the paragraphs that make the request free and enforceable. Under 29 CFR 2560.503-1(h)(2)(iii), relevant documents come free of charge; a copying fee is a sign the request was not read as a claims-procedure request.
Most behavioral-health appeals are written against a sentence. The notice says criteria were not met, names a guideline nobody has read, and the appeal that follows argues with a summary rather than with the decision. The claim file is how you see the decision: the criteria actually applied, the reviewer who applied them, the records they had in front of them, and whatever internal rule shaped the outcome.
For plans governed by ERISA — which covers most employer-sponsored coverage — this is not a favour. The claims procedure regulation requires the plan to give a claimant reasonable access to, and free copies of, all documents relevant to the claim, and it defines relevant broadly enough to reach internal guidelines and the records generated while deciding. The letter below asks for those items by paragraph.
Key takeaways
The short version
- Under 29 CFR 2560.503-1(h)(2)(iii), relevant documents come free of charge; a copying fee is a sign the request was not read as a claims-procedure request.
- Paragraph (m)(8) defines relevant to include what was relied upon, submitted, considered, or generated in deciding — which is broader than the medical records you sent.
- Ask for the internal rule or guideline explicitly. If one was relied on, the plan must say so and provide it free on request.
- File the request the same day you calendar the appeal deadline. The 180-day window under (h)(3)(i) does not pause while you wait.
- The right belongs to the participant or beneficiary, so a provider sends this as an authorized representative with a signed designation attached.
- Medicare Advantage and Medicaid managed care have their own document and appeal rules; this letter is for ERISA group health plans.

ERISA claim file request letter
A paragraph-cited request for the criteria applied, internal rules, reviewer credentials, records considered, internal notes, and any automated decision output, with an authorized-representative block.

1. What the regulation actually entitles you to
The claims procedure regulation sets out what a full and fair review requires. Two paragraphs do most of the work. Paragraph (h)(2)(iii) requires the plan to provide the claimant, on request and free of charge, reasonable access to and copies of all documents, records, and other information relevant to the claim. Paragraph (m)(8) then defines relevant, and the definition is wider than people expect: a document is relevant if it was relied upon in making the determination, or was submitted, considered, or generated in the course of making it, among other categories.
That second clause matters because it reaches past your own submission. Internal review notes, the reviewer's worksheet, the version of the criteria applied, and records created while the decision was being made all fall inside it even though you never sent them. Asking for the medical records you already have is a wasted request; asking for what the plan generated is the point.
| Ask for | Why it is reachable | What it tends to show |
|---|---|---|
| The criteria or guideline applied, with edition and version | Relied upon in making the determination | That a different or superseded standard was applied than the one you documented to |
| Any internal rule, protocol, or administrative guideline | The regulation requires disclosure of internal rules relied on | An unpublished rule narrower than the plan document or the criteria set |
| Reviewer identity, credentials, and specialty | Generated in the course of the determination | That a non-specialist or non-clinician reviewed a specialty question |
| The records the reviewer had | Submitted or considered | That records you sent were missing from the file at decision time |
| Internal notes, worksheets, and scoring | Generated in the course of the determination | The actual reasoning, including which criterion was scored as unmet |
| Any automated decision support or algorithmic output | Considered or generated in the course of the determination | Whether a tool produced the result before a clinician saw it |
| The plan document and summary plan description language on medical necessity | Governs the benefit at issue | That the plan's own definition is broader than the criteria applied |
2. Who may make the request
The right runs to the claimant — the participant or beneficiary — not to the provider as a vendor of services. A provider can exercise it, but as the patient's authorized representative, and the plan is entitled to require that the designation be reasonable and documented. This is the single most common reason a well-drafted request is refused on paperwork grounds.
The operational fix is to stop treating the designation as an appeals artifact. Collect it at admission, alongside consents, for every patient with employer-sponsored coverage. By the time a denial arrives the window is already running, and chasing a signature from a discharged patient is slow at exactly the wrong moment.
- Get the authorized-representative designation signed at admission, not at denial.
- Keep it specific: name the plan, the claim or episode, and the scope (claims, appeals, and document requests).
- Attach it to the request. A letter that asserts representative status without evidence invites a refusal that costs two weeks.
- Check the plan's own designation form; some plans require theirs, and using it removes an argument.
- For substance use disorder records, 42 CFR Part 2 consent requirements apply on top of the plan's paperwork, and they are not interchangeable.
- Where the patient will not or cannot sign, the appeal is the patient's to bring, and your role shifts to supplying clinical documentation.
3. Timing: request early, appeal on schedule
The appeal deadline for an ERISA group health plan is 180 days from the adverse benefit determination under paragraph (h)(3)(i). Nothing about requesting documents extends it. The practical sequence is therefore to send the request immediately, calendar the appeal deadline on the same day, and file the appeal on time whether or not the file has arrived — noting in the appeal that the request is outstanding.
That note is not a formality. An appeal decided while the plan is sitting on documents it was required to produce is an appeal in which the claimant was denied a full and fair review, and that is a separate and sometimes stronger argument than the clinical one.
| Day | Action | Why |
|---|---|---|
| 0 | Notice received; log criteria set, criterion, reviewer, decision date | Everything downstream depends on reading the notice as data |
| 0 | Calculate and calendar the 180-day appeal deadline | The clock starts now and does not pause |
| 0–1 | Send the claim file request with the designation attached | Earliest possible start on the plan's response time |
| 7 | Chase if nothing acknowledged | Creates a record of diligence |
| Before the deadline | File the appeal, noting the outstanding request | Preserves both the clinical and the procedural argument |
| On receipt of the file | Supplement the appeal with what the file shows | The file usually changes which argument is strongest |
4. How to read the file when it arrives
- 01
Compare the criteria applied against the criteria you documented to
Note the edition and version. A mismatch between the standard you wrote to and the standard applied is often the whole case.
- 02
Check the reviewer against the question
Record name, credentials, and specialty. A question about withdrawal management reviewed by a non-specialist is a specific, documentable objection.
- 03
Inventory what was missing
List the documents you submitted and the documents the file shows were considered. Records absent at decision time are grounds to have the decision reconsidered on a complete record.
- 04
Look for an internal rule
If an unpublished guideline narrower than the plan document drove the outcome, say so plainly and quote both.
- 05
Look for automation
Note any algorithmic output, score, or decision-support artifact, and when a human reviewed it relative to the decision timestamp.
- 06
Decide which argument leads
Procedural defects and clinical merits are both available. Lead with whichever the file supports best, and keep the other in its own section.
5. Turning this into a standing step
- Make the request automatic for every commercial denial above a dollar or level-of-care threshold you set, rather than a judgement call per case.
- Template the letter once, then vary only the identifying block. The citations do not change.
- Track request date, acknowledgement date, receipt date, and what the file revealed, so you learn which plans comply and which do not.
- Log whether an internal rule or automated output appeared. A pattern across cases is far more persuasive than one instance.
- Measure overturn rate for appeals filed with the file versus without it. That number tells you what this step is worth at your volume.
- Review refusals with your compliance lead. A plan that charges for copies or ignores a documented request is a conversation above the appeals desk.
Common questions
Answers before you build.
Does this letter work for Medicare Advantage or Medicaid denials?+
No. The citations here are the ERISA claims procedure regulation, which governs employer-sponsored and other ERISA group health plans. Medicare Advantage runs under 42 CFR part 422 and Medicaid managed care under 42 CFR part 438, each with its own notice, record, and appeal rules. Identify the plan type before choosing the letter.
Can the plan charge us for the copies?+
Not for documents relevant to the claim requested as part of an appeal. Paragraph (h)(2)(iii) provides for reasonable access and copies free of charge. If a fee is quoted, restate the basis of the request in writing.
How long does the plan have to produce the file?+
The regulation ties document access to the appeal process rather than setting a single universal production deadline, so treat the plan's own stated timeframe as the working expectation and document every delay. The point of filing early is that a slow response then becomes evidence rather than a problem.
Is a request for the criteria the same as a request for the claim file?+
No, and asking only for criteria leaves most of the value behind. Criteria tell you the standard; the file tells you how the standard was applied, by whom, and on what record. Ask for both in the same letter.
What if the plan says no internal rule was relied upon?+
Record the answer and keep it. A written statement that no internal rule applied is useful later if the plan's position shifts, and it narrows the dispute to the criteria and the record.
