A treatment gap is a period in an injury claim during which the claimant received no documented care for the injury at issue. On a timeline it is an empty stretch: a last visit, then nothing, then care resumes. Gaps show up in nearly every case with a treatment history longer than a few months, and nearly every one of them gets argued about, because a gap is one of the few facts in a medical record that both sides can read without a physician.
The defense reads a gap as evidence about the injury. If the claimant went ninety days without seeing anyone, the argument runs, the injury either resolved or was never severe enough to need care, and what came after the gap was a new problem, a new incident, or a decision to build a claim. Insurance adjusters apply the same reasoning when they value a file, and some carriers reduce offers mechanically once a gap passes a threshold.
The plaintiff's side needs to explain the gap before the defense characterizes it. Most gaps have an explanation sitting somewhere in the record: a discharge from physical therapy with a home program, a note that the patient could not afford the copay, a referral that took weeks to schedule, a provider who left the practice, a pregnancy, a job that would not give time off, a treating physician who said there was nothing more to offer. A gap with a documented reason is a scheduling fact. A gap with no reason in the record is a problem for whoever bears the burden.
This is the question that decides most gap arguments, and it is the one a raw record does not answer. A stretch that looks empty is often empty only in the production. The clues are in the pages on either side of it. A note that says "continue PT three times weekly" followed by no therapy entries usually means the therapy records were never requested. A pharmacy fill history with refills during the gap means someone was prescribing. A specialist note that opens with "seen in follow-up" implies an earlier visit that is not in the file. An MRI report dated inside the gap means an ordering provider and a visit that produced the order.
A chronology built from every page makes these clues visible because the entries on both sides of the gap sit next to each other. The reviewer's flag reads something like: no encounters between March 14 and July 2; PT discharge note of March 14 references a four-week home program; pharmacy record shows cyclobenzaprine refills April 9 and May 11 by Dr. R., no corresponding office notes in production. That single flag tells the plaintiff what to request and tells the defense what not to argue yet.
Some periods without care are the expected course of the condition. A soft-tissue injury treated for six weeks and then released is not a gap; it is a discharge. A surgical patient who is seen at two weeks, six weeks, and three months has a standard follow-up schedule, and the spaces between those visits are not absences of care. A reviewer who knows clinical practice reads these correctly. A reviewer who does not will flag every empty month, which leaves the one gap that matters among twenty that do not.
Three kinds of gap carry more weight than the rest. The first is the gap at the very start, between the incident and the first visit; a claimant who waits three weeks to see anyone invites the argument that the injury was minor or came from somewhere else. The second is the gap immediately before the claim is filed or counsel is retained, which the defense will read as treatment resumed for litigation. The third is a gap that ends with a new mechanism: a fall, a second collision, a lifting injury at work. That last one is less a gap than a break in the causal chain, and it changes the case.
For the plaintiff, the work is to complete the record before the argument starts: request the therapy notes, the pharmacy history, the primary care chart, and the employer's records, and be ready to explain what remains. For the defense, the work is to confirm the gap survives a full production before building on it. A gap argument that collapses when the plaintiff produces the missing PT notes at deposition costs credibility with the adjuster and the mediator.
Either way, the gap has to be found first, and it has to be found in the whole record. Sampling the "important" providers is how gaps get missed, because the explanation for the gap is almost always in a record nobody thought was important.
There is no fixed number. Adjusters and defense counsel start paying attention somewhere around thirty to sixty days for an active injury, but a two-week gap right after the incident can matter more than a three-month gap two years later. Context in the record decides it.
Only if the record shows the patient was supposed to be attending. A discharge to a home exercise program is not a gap. Missed appointments while still on an active plan of care are, and therapy attendance logs usually document them.
Often, and treating providers frequently document it: a note that the patient declined the MRI for cost, or could not afford the copay. Those notes are the explanation, which is one reason to read every page rather than the specialist records alone.
As a flagged entry in the timeline with the start and end dates, the last encounter before and the first after, and any record evidence that care continued elsewhere. The flag states what the record shows; what the gap means for the claim stays with you.
