When an insurance adjuster reviews your medical records after a car accident, they are not reading them the way your doctor reads them. Your doctor is looking for clinical information that helps them treat you. The adjuster is looking for information that helps them pay you less. Those are different reading projects, and they produce different things from the same documents. Understanding specifically what an adjuster is hunting for when they open your file changes how you think about every medical visit you have had since the accident, every conversation you have had with a provider, and every piece of paper that is going to end up in front of them.
The first thing an adjuster looks for is the treatment gap. A treatment gap is any period of time between your accident and your first medical visit, or any period of time during your course of treatment where you did not see a provider for an extended stretch. Insurers treat gaps in treatment as evidence that your injuries are not as serious as you claim. The logic they apply is straightforward and worth understanding on its own terms: if you were in genuine pain, you would have sought treatment sooner and you would have maintained consistent treatment throughout your recovery. Any deviation from that pattern becomes an argument for reducing the value of your claim. This is true even when the reason for the gap has a completely innocent explanation, whether you were waiting for insurance coverage to sort out, you were trying to manage with over the counter medication, you were too busy with work or family obligations to make appointments, or simply because you hoped the pain would resolve on its own. The adjuster does not weigh the explanation. They flag the gap.
Closely related to the treatment gap is the question of whether your first medical visit happened at an emergency room or urgent care facility immediately after the accident, or whether days or weeks passed before you saw anyone. Adjusters are trained to use delayed initial treatment as a cornerstone argument against the severity of your injuries. The counterargument, that adrenaline frequently masks pain in the immediate aftermath of a crash, that soft tissue injuries often do not fully manifest until twenty-four to seventy-two hours after impact, and that people reasonably try to avoid expensive emergency room visits for what they hope will resolve on its own, is true but not automatically persuasive once the delay is documented in your records. The absence of an immediate medical visit becomes a fact in your file, and facts in your file do not disappear.
The second major category of scrutiny is pre-existing conditions. Adjusters are specifically looking for any prior treatment involving the same body parts or general regions you are now claiming were injured in the accident. If you have ever seen a doctor for back pain, neck stiffness, headaches, knee problems, or shoulder complaints, and those complaints appear anywhere in your prior medical records, the adjuster will use that history to argue that your current injuries are either a continuation of a pre-existing condition or an aggravation of one, rather than a new injury caused by the accident. In Missouri, as in most states, the aggravation of a pre-existing condition is still compensable. A defendant takes a plaintiff as they find them, and if the accident made an existing condition meaningfully worse, the at-fault driver is responsible for that worsening. But that legal principle does not prevent adjusters from using prior medical history to confuse the causation picture and depress their settlement offer. The more pre-existing history they can find, the more aggressively they will argue that the accident is not responsible for what you are experiencing now.
This is precisely why a blanket medical authorization, the kind discussed elsewhere in this series, is so valuable to the insurer. They are not asking for your complete medical history out of idle curiosity. They are looking for any prior documentation of complaints that overlap with your current injuries. A single entry in a primary care visit from three years ago noting that you mentioned occasional lower back stiffness can become, in an adjuster’s hands, evidence that the herniated disc you are now treating was already there before the accident. Whether that inference is medically accurate is almost beside the point at the negotiation stage. It becomes an argument they make, and it becomes something you have to counter.
The third thing adjusters examine closely is the consistency of your subjective complaints across providers and over time. Your medical records contain two distinct types of documentation: objective findings, meaning things your providers observed or measured, such as imaging results, range of motion measurements, visible bruising or swelling, and positive orthopedic tests; and subjective complaints, meaning what you reported to your providers about your pain, your symptoms, and how your injuries are affecting your life. Adjusters pay particular attention to the subjective complaint entries because they are looking for inconsistencies. If you reported a pain level of eight out of ten to one provider and a four out of ten to another provider around the same time, that discrepancy will be noted. If you told your physical therapist you were doing much better but did not update your attorney or the insurer about that improvement, the physical therapy notes become a tool for arguing your condition resolved earlier than you are suggesting. If your complaints to providers do not align with what you have told the insurance company, the adjuster will use that misalignment to challenge your credibility.
The insight that most people never receive about their own records is this: your medical records are not a neutral clinical document. They are a contemporaneous written record of everything you said and everything your providers observed, and every entry was made without any thought given to how it would read to someone trying to minimize your damages. Clinicians document quickly, in the context of busy practices, using shorthand and standardized language that was designed for medical communication rather than legal advocacy. An entry that reads “patient reports improvement” may accurately capture that you felt better on a particular day without capturing that you still have significant pain, that the improvement was relative to a very low baseline, or that you subsequently worsened again. The adjuster reading that entry sees improvement. They do not see the context your provider understood implicitly.
Functional limitations are another category adjusters examine with specific intent. They are looking at whether your providers have documented concrete restrictions on your ability to work, perform daily activities, or engage in activities that were part of your life before the accident. Vague language about pain does not serve your claim as well as specific documented limitations. A note that says a patient has chronic pain is worth less, in the adjuster’s framework, than a note that says a patient cannot sit for more than twenty minutes without significant pain, cannot lift more than ten pounds, and has been restricted from returning to their previous job duties. The specificity of functional limitation documentation directly affects how the adjuster calculates the non-economic component of your damages, because it gives them either a concrete picture of life impact to take seriously or a vague pain complaint to discount.
Adjusters also look at the type of treatment you received and whether it was consistent with the nature and severity of the injuries you are claiming. If you are claiming a serious spinal injury but your treatment has consisted only of a few chiropractic visits, the insurer will argue that the treatment history does not support the severity of the injury. If your treating physician has recommended surgery but you have not pursued it, the insurer may argue that your refusal of recommended treatment breaks the chain of causation or demonstrates that your injuries are not as limiting as you claim. Conversely, if you have received extensive treatment including multiple specialists, imaging, injections, and physical therapy, that treatment history supports the seriousness of your claim in a way that a thin treatment record cannot.
Prescription history receives attention for a related reason. Adjusters note whether you were prescribed pain medication, muscle relaxants, or other medications consistent with the type of injury you are claiming, whether those prescriptions were filled, and whether they were maintained over time. A person claiming severe chronic pain who was never prescribed anything stronger than over the counter anti-inflammatories presents differently than someone whose records show a progression of prescription pain management consistent with the injury they are describing. Neither picture is definitive, but both are read by adjusters as supporting or undermining the severity narrative your claim depends on.
What all of this adds up to is a reading of your medical records that is adversarial rather than clinical, looking not for what your records say about your health but for what they can be made to say about the limitations of your claim. Understanding that the adjuster who calls you with a settlement offer has already done this analysis, has already identified the gaps and inconsistencies and pre-existing conditions and subjective complaint discrepancies they plan to use to justify the number they are presenting, changes how you receive that offer. They did not arrive at their number through a good faith effort to value your damages. They arrived at it through a systematic search for everything in your own records that can be used against you. The offer reflects what they found.
