I felt fine at the scene and saw someone days later. Does that matter?

Here is the question, in the words people actually use: I felt fine at the scene. I said so. I drove home, and it was three or four days before I saw anyone about my neck. Does that matter now? It is usually answered badly, by someone selling something, in the form of an instruction about the reader’s body.

The shortest true answer is: yes, it matters, and not for the reason most people assume. An injury claim is not an account of what happened to a person. It is a file, and the instruments that decide what gets paid out of that file are written about documents. In one market the interval is not evidence at all but a term of the coverage; everywhere else the instruments read here make payment run off dated proof, and the first dated document connecting a body to a crash is the one every later document is read against.

That is the answer; what follows is the qualifications, longest first. Nothing here says when anyone should seek care — it is about what a file must contain.

The longest qualification: sometimes the interval is not evidence, it is the coverage

Florida’s no-fault statute conditions the medical benefit on the interval directly. The benefit covers initial services and care lawfully provided, supervised, ordered or prescribed by a named list of licensed professionals, or provided in a hospital — and applies only where “the individual receives initial services and care pursuant to subparagraph 1. within 14 days after the motor vehicle accident.” That sentence assesses nobody’s injury: it is a condition, and a file satisfies it or does not.

The same subsection does something less noticed and more revealing. Reimbursement runs up to $10,000 where a listed provider “has determined that the injured person had an emergency medical condition”, and is “limited to $2,500” where the provider determines otherwise. The ceiling on a statutory benefit turns on a determination recorded by someone the statute names. Not on the injury. On the record of a finding about it.

Whether a reader’s market runs a no-fault first-party benefit at all, and whether it carries a window of the Florida kind, is in the jurisdiction notes below.

The payment clock starts when the proof arrives, not when the crash happened

Two statutes, drafted separately, say the same structural thing.

Florida: personal injury protection benefits “are overdue if not paid within 30 days after the insurer is furnished written notice of the fact of a covered loss and of the amount of same”, with the insurer entitled to “reasonable proof of such loss and the amount of expenses and loss incurred which are covered by the policy.”

New York: first party benefits “are overdue if not paid within thirty days after the claimant supplies proof of the fact and amount of loss sustained.” Overdue payments bear interest at two percent per month, and a claimant with an overdue valid claim may recover a reasonable attorney’s fee for services necessarily performed in securing payment.

Read them as machinery rather than as deadlines. The thirty days hangs off an act of supply. Until a document exists, nothing has been supplied, no clock has started and no payment can be late. A person in pain for a month who has generated no paper has, in the statute’s terms, not yet begun.

Two other no-fault statutes carry a comparable reasonable-proof requirement and neither could be read: Michigan’s legislature could not be reached over a connection this machine could verify, on two attempts, and Hawaii’s returned an HTTP 403. Neither is quoted here or described from memory.

Spain writes the whole mechanism out, on both sides

The Spanish motor liability statute is unusually explicit about what a claim consists of, because it says out loud what other systems leave to practice.

The pre-suit claim a person must send before going to court has a required content, part of it medical: it must carry «cuanta información médica asistencial o pericial o de cualquier otro tipo tengan en su poder que permita la cuantificación del daño» — whatever medical, care or expert information the claimant holds that allows the harm to be quantified. The claim need not even be quantified; the documents are what must travel.

Article 37 then states the rule the rest of the title depends on: “La determinación y medición de las secuelas y de las lesiones temporales ha de realizarse mediante informe médico ajustado a las reglas de este sistema” — sequelae and temporary injuries are determined and measured by a medical report conforming to the system’s rules. It adds a duty running the other way: from the moment the harm occurs, the injured person must give the collaboration needed for the medical services appointed on the eventual liable party’s account to examine them and follow the course of the injuries, and a failure to do so counts as a cause not attributable to the insurer for default interest.

Then the part almost nobody mentions, because it cuts against the insurer. Within three months the insurer must produce a reasoned offer or a reasoned refusal. A valid offer must contain, itemised and in detail, the documents available for valuing the harm, “incluyendo el informe médico pericial definitivo”, and identify the ones the figure was based on. And if it does not: “El incumplimiento de este deber impedirá la aportación de informes médicos periciales definitivos en el posterior proceso judicial.” The document withheld from the file cannot be produced in court later. The same sanction attaches to a reasoned refusal, which must also state the motive that prevents an offer.

That is this article’s thesis, made by a legislature rather than by us: a party who keeps a medical document out of the file loses the use of it. It happens to apply to insurers. It describes the reader’s position exactly.

The one instrument that names an interval, and what it is actually for

The same Spanish statute contains the only numbered interval found in anything read for this article, and it must be read for what it is. Article 135 sets out criteria of generic causation for minor cervical trauma — injuries diagnosed on the basis of the person’s own report of pain that complementary tests cannot verify — and those criteria are addressed to the people who assess a file. Among them is the chronological criterion: “que la sintomatología aparezca en tiempo médicamente explicable. En particular, tiene especial relevancia a efectos de este criterio que se hayan manifestado los síntomas dentro de las setenta y dos horas posteriores al accidente o que el lesionado haya sido objeto de atención médica en este plazo.”

Two things about that clause, both about drafting rather than about bodies. It is a standard of proof of causation, not an instruction to anyone: the statute is telling an assessor what carries weight, and this article passes that on without adding to it. And the two limbs are alternatives joined by “o” — symptoms having manifested within the period, or the person having been the subject of medical attention within it.

This article offers no view on what a person should do, and no interval of its own. It reports that one legislature attached evidentiary significance to a documented interval, in one class of injury.

What the report is made of

England and Wales route the smaller road traffic injury claims through a pre-action protocol, and it is blunt about where a medical opinion comes from. The claimant “should obtain a medical report, if one has not already been obtained”, and must check its factual accuracy before it goes to the defendant. The expert should identify within the report “(a) the medical records that have been reviewed; and (b) the medical records considered relevant to the claim.”

That last requirement is the whole argument in one line. The expert’s product is assembled out of records and has to say which ones. In a soft tissue claim the first report must be a fixed cost medical report from an accredited expert selected through the MedCo Portal, and one report is expected to do — so the file gets one opinion, built from the records that exist when it is written. A record that was never created cannot be reviewed, listed, or relied on.

American federal courts arrive at the same place through the rule against hearsay. Rule 803(4) admits a statement “made for—and is reasonably pertinent to—medical diagnosis or treatment” that “describes medical history; past or present symptoms or sensations; their inception; or their general cause”. Rule 803(6) admits a record of an act, condition, opinion or diagnosis “made at or near the time by—or from information transmitted by—someone with knowledge”, kept in a regularly conducted activity. A clinician’s note about when something started is admissible because of when and why it was written; a description assembled afterwards, for the claim, has neither quality.

The file is also something you can hold

Two of the instruments read here point back at the reader. Under the United States federal privacy rule, an individual “has a right of access to inspect and obtain a copy of protected health information about the individual in a designated record set”, on a clock and at a capped fee — the terms are in the questions below. The file is not something the reader has to guess at.

And the insurer’s reasoning is itself a document. Florida’s unfair claim settlement practices provision makes it an unfair practice to fail “to promptly provide a reasonable explanation in writing to the insured of the basis in the insurance policy…for denial of a claim”, or to deny claims “without conducting reasonable investigations based upon available information” as a general business practice. Spain’s reasoned refusal does the same work in a different register.

The section’s claim readiness checklist, opened on its injury mode, lists the documents these instruments name — records, dated proof of loss, income evidence — and nothing else. It assembles a file. It does not assess an injury, and it cannot.

What we cannot tell you

We cannot tell you how much weight a gap in a treatment history carries once a claim is argued, because we did not open a court’s own published opinion for this article. Everything above comes from statutes, a protocol and two rules of evidence, which say what a file must contain and when payment falls due; none of them says what an adjudicator will make of an interval.

We cannot tell you when to see anyone, and we have not tried. That is a medical question, this is a claims article, and the only interval quoted in it is a legislature’s rule for assessing proof of causation.

And we cannot give you a number of days that travels. Florida’s fourteen is a condition of one state’s statutory benefit; Spain’s seventy-two is an evidentiary criterion about one kind of injury; New York’s and Florida’s thirty days measure the insurer’s conduct, not the reader’s. Four clocks, attached to four different things. What they have in common is the point that survives the differences: each starts running off a document, and no document has ever been created retroactively.
