A medical chronology is the treatment history of one person rebuilt as a single dated timeline: every visit, study, procedure, and provider, in order, with the source page for each entry. Law firms order one because the record itself arrives in no usable order. It comes from six facilities in six formats, sorted by whoever printed it, with the entry that decides the case sitting on page 1,140 between a nursing flowsheet and a duplicate fax cover. The chronology puts that entry where a lawyer can find it and cite it.
What follows is how firms actually use the document at each stage, and what that stage needs from it.
The first question is whether the case is worth the firm's time, and the record answers it faster than the client does. A chronology built at intake shows the mechanism of injury as the first treating provider recorded it, how soon care started, whether the complaints stayed consistent across providers, and whether the same body part appears in records that predate the incident. Firms that order early tend to order the plainer tier, because at this stage they need the facts laid out, not a second opinion on them.
Two things in the timeline change an evaluation more than anything else: a gap in treatment and a prior complaint. Both are easy to miss in a raw record and impossible to miss on a timeline, which is the point.
A demand letter tells the story of the injury in the order it happened, and the adjuster reading it will check the story against the records attached. A chronology gives the drafter the dates, the providers, and the record language to quote, so the demand rests on what the chart says rather than on paraphrase. The medical specials section of a demand is a chronology with billing attached; building the two together avoids the mismatch that adjusters look for first, treatment listed in the specials that never appears in the notes.
Once the record is on a timeline, the missing records become visible. A referral in one note with no corresponding specialist record, an MRI ordered but never reported, a pharmacy history that implies a prescriber who is not in the production. Each one is a records request or a subpoena the firm would otherwise not know to send. Defense firms use the same list in reverse, to find the treatment the plaintiff's production left out.
The chronology also drives the deposition outline for treating providers. A treater deposed with the timeline in hand gets asked about the specific visit on the specific date, with the page number ready.
Experts bill by the hour, and the first hours on any file go to reading. A chronology delivered with the retention letter lets the expert start with the record already organized, spend their time on the questions that need a physician, and cite the chronology's page references in their own report. The expert's opinion still rests on their own review of the source pages; the chronology tells them which pages to review first.
The boundary matters here. A chronology states what the record shows. It does not say what caused what, whether care was reasonable, or whether an impairment is permanent. Those are the expert's opinions, and keeping the chronology on the fact side of that line is what keeps it useful and admissible as a summary of the records.
When the other side's examiner has written a report, the chronology is the check against it. Every factual statement in the report can be run against the timeline: did the record actually say that, on that date, from that provider? An examiner who has summarized 2,000 pages from memory will get some of it wrong, and the chronology is where those errors surface. Firms that want the comparison done for them order a deposition guide, which pairs the timeline with an analysis of the expert's report and the lines of questioning it opens.
At mediation, the chronology becomes the one-page exhibit. A clean timeline with the key entries marked lets a mediator, or an adjuster with settlement authority, see the case the way the firm sees it without reading a binder. The firms that get the most from this stage bring a timeline that a stranger can follow in two minutes.
Ask for every accessible page, not a sample. Ask for page citations on every entry so anyone can go back to the source. Ask who did the reading; a nurse practitioner, physician assistant, or physician reads a chart differently from a paralegal, and the difference shows up in what gets flagged. And ask for the file in Word as well as PDF, so the timeline can be cut down into exhibits and deposition outlines without retyping.
Firms use chronologies as demonstrative aids at mediation and, subject to the rules in the jurisdiction, as summaries of voluminous records under rules like Federal Rule of Evidence 1006. The underlying records still have to be produced and admissible. Ask your own counsel about the rule that applies to your court.
A summary condenses the record; a chronology organizes it in time. Good record review does both at once, with the timeline as the structure and each encounter summarized in its place. The NaviCase Record Summary is that combination.
No. A chronology reports what the record shows. Causation, reasonableness of care, and permanency are opinions for a retained expert, and mixing them into the chronology weakens both documents.
As early as the record is reasonably complete. A chronology at intake changes case evaluation, and the records requests it identifies take time to complete. Firms that wait until the expert is retained pay the expert to do the organizing instead.
NaviCase charges $0.25 per page for the Record Summary and $0.40 per page for Summary + Analysis, with a $150 case minimum. A 2,000-page case is $500 or $800. Standard turnaround is five business days.
Every accessible page, in order, read by a clinician in active practice. $0.25 per page.
