What Do Insurance Companies Look For in Your Medical Records?
After an accident, the insurance company will ask for your medical records. They will tell you it is routine, just something they need to process your claim. That part is true. What they will not tell you is what they are actually reading those records for.
An adjuster does not open your file hoping to pay you fairly. They read it the way an opposing party reads anything, looking for the line, the gap, or the old diagnosis that lets them pay you less. Knowing what they are hunting for is the first step to protecting your claim.
As an attorney who spent years as a physician assistant before practicing law, I read these records the same way the insurance company's reviewer does, which is exactly why I can see the traps coming. Here is what they look for.
Quick answer: Insurance companies review your medical records to find reasons to reduce or deny your claim. Specifically, they look for pre-existing conditions they can blame your injuries on, gaps or delays in your treatment, inconsistencies between your reported symptoms and the records, treatment they can label unnecessary, and any prior injury to the same part of your body. They also request records going back years, often three to five and sometimes ten or more, hoping to find something unrelated to use against you. You are not required to hand over your entire medical history, and limiting what they see is one of the most important ways to protect your claim.
Pre-Existing Conditions They Can Blame Your Injuries On
This is the first thing an adjuster looks for. If you injured your lower back in a car accident, they will dig through your history for any prior back complaint, even a minor one from years ago, and argue that your pain was already there before the crash.
Insurers typically request records covering three to five years before your accident, and for spinal injuries, head injuries, or other conditions with long-term progression, they often go back seven to ten years or more. The goal is to find a prior diagnosis, a single doctor's note, or even a routine checkup mention they can use to claim your injury is old news.
Here is what they count on you not knowing. Under California law, a pre-existing condition does not bar your claim. The eggshell plaintiff rule means a defendant takes you as they find you, so if the accident aggravated a prior condition, that aggravation is compensable. Proving the difference between old and new, though, takes someone who can actually read the imaging and the clinical notes and explain what changed.
Gaps and Delays in Treatment
Adjusters scrutinize the timeline. If you waited two weeks to see a doctor, or missed appointments, or stopped treatment partway through, they will use it. The argument is always the same: if you were really hurt, you would have gone sooner and gone consistently.
That argument ignores how injuries actually behave. Adrenaline masks pain for days after a crash. Soft tissue injuries often worsen over the following week. People miss appointments because they cannot afford to miss work, not because they are healed. But on paper, a gap looks like a hole in your case, and the adjuster will treat it as one unless it is explained in medical terms.
Inconsistencies Between Your Symptoms and the Records
The insurance reviewer compares everything you have said against everything in the file. What you told the adjuster, what you told the emergency room, what you told your treating physician, and what the records document. Any mismatch becomes ammunition.
This is also why your medical bills must line up with your medical reports. If a bill is submitted without a corresponding report documenting the treatment and the reason for it, the adjuster can discount that expense entirely and refuse to pay it. A claim that is not internally consistent is a claim they will pick apart.
Treatment They Can Call Unnecessary or Excessive
Adjusters routinely second-guess your care. They will label treatment unnecessary, claim you saw a provider too often, or argue the same recovery would have happened with less. They are not doctors, but they make these calls anyway, and an unchallenged label sticks.
This is where medical training changes the conversation. When the insurer argues a course of treatment was excessive, it takes clinical knowledge to explain why the care was appropriate for the diagnosis. That is an argument a non medical attorney often cannot make with the same authority, and it is one adjusters are not used to losing.
Prior Injuries to the Same Body Part
Related to pre-existing conditions but worth its own mention, because it is the single most common tactic. Hurt your shoulder now, and any prior shoulder complaint becomes their explanation. Hurt your neck now, and a whiplash claim from a decade ago resurfaces. The adjuster does not need the prior injury to be similar or recent. They only need it to exist, so they can muddy causation.
Why You Should Never Sign a Blanket Medical Release
When the adjuster sends paperwork, it usually includes a medical authorization. Read it carefully, because most are written to give the insurer open access to your entire medical history from every provider you have ever seen.
Do not sign that. A blanket release is an invitation for a fishing expedition, the exact process described above where they hunt through unrelated records for anything usable. You can provide the records relevant to this accident without surrendering your whole file. The authorization should be limited to the body parts at issue and the relevant time frame, and an attorney can control precisely what gets disclosed.
The Deadline Still Matters
While you are managing what the insurer sees, the clock keeps running. In California you generally have two years from the date of injury to file a personal injury lawsuit under Code of Civil Procedure section 335.1, and only six months to file a claim against a government entity under Government Code section 911.2. Protecting your records does not pause those deadlines.
Frequently Asked Questions
Do I have to give the insurance company my medical records?
You must provide records relevant to the injuries you are claiming, but you are not required to hand over your entire medical history. You can and should limit access to records related to the accident.
How far back can an insurance company request my records?
Insurers commonly request three to five years of history, and for spinal or head injuries they often seek seven to ten years or more. You do not have to agree to an unlimited time frame.
Can I still recover if I had a pre-existing condition?
Yes. Under California's eggshell plaintiff rule, you can recover for the aggravation of a pre-existing condition. The defendant takes you as they find you.
Should I sign the medical release the adjuster sent me?
Not without reviewing it first. Most are written for full access. Limit any authorization to the relevant body parts and time period, or have an attorney handle it.
Why does it matter if my lawyer understands medicine?
Insurance companies argue about causation, treatment necessity, and the meaning of clinical findings. An attorney who can read and interpret the records directly can challenge those arguments where a non medical attorney may not.
