How Insurance Companies Use Medical Record Reviews to Dispute Injuries

Michael Pines | August 2, 2026 | Personal Injury

Quick Insights

• Insurance companies review medical records to identify reasons to dispute whether an accident caused an injury, how serious the injury is, and whether all treatment was necessary.
• Adjusters may rely on independent medical examinations, physician peer reviews, nurse reviews, or utilization-review processes to challenge a treating provider’s conclusions.
• Gaps in treatment may be portrayed as proof that an injury resolved, even when care was interrupted by cost, scheduling, transportation, insurance, or referral delays.
• Prior injuries and medical conditions do not automatically defeat a personal injury claim, but insurers may argue that current symptoms existed before the accident.
• Reviewers may emphasize normal test results or isolated favorable notes while minimizing documented pain, functional limitations, specialist opinions, or worsening symptoms.
• Consistent treatment, accurate medical histories, clear documentation, and careful review of the complete medical record can help counter misleading interpretations.

Medical records are among the most important forms of evidence in a California personal injury claim. They document diagnoses, symptoms, examinations, treatment recommendations, imaging results, medications, referrals, work restrictions, and the ways an injury affects a patient’s daily life.

They can also become one of an insurance company’s primary tools for disputing the claim.

An adjuster may send hundreds or thousands of pages of medical records to a physician, nurse, or claims reviewer and ask whether the accident caused the claimed injuries, whether the treatment was reasonable, and whether the patient has recovered. The reviewer may never have treated the injured person and, in some cases, may never meet them.

Insurance companies may describe these reviews as objective evaluations. A medical review can identify legitimate questions, and insurers are entitled to investigate claims. Problems arise, however, when records are interpreted selectively, ordinary inconsistencies are exaggerated, or a reviewing professional discounts the opinions of doctors who repeatedly examined and treated the patient.

Understanding how these reviews work can help injured Californians recognize the arguments an insurer may use to reduce or deny compensation.

Why Do Insurance Companies Examine Medical Records?

A person seeking compensation for bodily injuries generally must establish a connection between the accident and the harm for which compensation is requested.

Medical records may help answer questions such as:

• When did the symptoms begin?
• What body parts were injured?
• What diagnoses were made?
• Did the patient report the accident consistently?
• What treatment was recommended?
• Did the patient follow medical advice?
• Were symptoms improving or worsening?
• Did the person have similar complaints before the accident?
• Are the injuries affecting work or ordinary activities?
• Will future care be necessary?

An insurer may use the same records to search for arguments against the claim.

The insurance company might contend that:

• The injury existed before the accident
• The symptoms began too long after the accident
• Treatment was excessive
• Treatment was unrelated to the crash
• The patient recovered earlier than claimed
• Diagnostic testing showed no significant abnormality
• The patient failed to follow medical recommendations
• A later event caused the continuing symptoms
• The claimed limitations are inconsistent with a medical note
• Future treatment is unnecessary

A claim can therefore depend not only on what the records say, but also on which portions the insurer chooses to emphasize.

What Is an Independent Medical Examination?

An independent medical examination, often called an IME, is an examination arranged by the defense or insurance company rather than by the injured person’s treating provider.

The term “independent” can be misleading. The examining physician is generally selected and paid by the defense, insurer, or claims administrator. The physician does not ordinarily establish an ongoing doctor-patient relationship or provide continuing treatment. The purpose is usually to evaluate issues relevant to the legal claim.

In California personal injury litigation, a defendant may demand one physical examination under specified circumstances when the plaintiff is seeking compensation for personal injuries. California Code of Civil Procedure section 2032.220 limits that examination in several ways, including restrictions on painful, prolonged, or intrusive procedures and a general location requirement.

An examiner may be asked to evaluate:

• Whether an injury exists
• Whether the accident caused or aggravated the condition
• Whether symptoms are supported by objective findings
• Whether treatment was reasonable
• Whether the patient has reached maximum improvement
• Whether additional care is necessary
• Whether work or activity restrictions remain appropriate
• Whether the patient has permanent impairment

The examination may include a medical-history review, physical testing, range-of-motion measurements, neurological testing, strength testing, and a review of imaging or other diagnostic studies.

Why an IME Can Affect a Personal Injury Claim

After the examination, the defense physician typically prepares a report. That report may agree with some diagnoses while disputing others.

For example, the examiner might conclude that:

• A strain should have resolved within several weeks
• Continuing pain is caused by age-related degeneration
• No further physical therapy is necessary
• Surgery is unrelated to the accident
• The patient can return to work without restrictions
• Subjective complaints are greater than the objective findings
• The accident caused only a temporary aggravation

The insurer may then cite those conclusions when reducing a settlement offer or disputing damages.

An IME report does not automatically override the records and opinions of treating physicians. It is one piece of evidence that should be evaluated alongside the patient’s complete treatment history, diagnostic testing, testimony, and functional limitations.

How Is a Peer Review Different From an IME?

A peer review is generally a paper review of medical records conducted by a physician or another qualified professional. Unlike an independent medical examination, the reviewer usually does not physically examine the injured person.

The reviewer may receive materials such as:

• Emergency-room records
• Primary-care notes
• Chiropractic records
• Physical-therapy notes
• Specialist reports
• Imaging reports
• Operative reports
• Billing records
• Prior medical records
• Deposition testimony
• Accident information

The reviewer may then issue an opinion about causation, diagnosis, medical necessity, duration of treatment, or prognosis.

A peer reviewer might argue that:

• The records do not establish a traumatic injury
• Imaging findings are degenerative
• Treatment continued longer than expected
• A procedure was not medically necessary
• The treatment frequency was excessive
• The patient’s symptoms should have resolved sooner
• There is insufficient documentation supporting future care

Because the reviewer does not examine or treat the patient, the opinion is based entirely on the records provided. Missing records, incomplete summaries, selective submissions, or a misunderstanding of the treatment timeline can affect the conclusions.

What Is Utilization Review?

Utilization review generally evaluates whether proposed or completed medical care meets standards for medical necessity, frequency, duration, and appropriateness.

The term can refer to different processes depending on the type of claim.

In California workers’ compensation cases, utilization review is a formal process used by employers or claims administrators to determine whether treatment recommended by a physician is medically necessary. California’s Division of Workers’ Compensation describes utilization review as the system used to approve, modify, delay, or deny requested treatment under applicable medical guidelines.

In an ordinary third-party personal injury claim, the process may be less formal. A liability insurer may have a physician, nurse, vendor, or claims professional review treatment to argue that certain services were unnecessary, unusually frequent, unrelated to the accident, or unreasonably expensive.

A utilization reviewer may examine:

• The number of therapy visits
• The length of chiropractic treatment
• The need for injections
• The basis for diagnostic imaging
• The timing of specialist referrals
• Whether surgery was appropriate
• Whether less costly care could have been used
• Whether treatment complied with published guidelines

The insurer may use the review to dispute the reasonable value of medical expenses, even when the patient’s own physicians believed the care was appropriate.

How Do Insurers Use Gaps in Medical Treatment?

A gap in treatment is a period during which an injured person does not receive documented medical care.

Insurance companies commonly argue that a treatment gap shows:

• The person was not seriously injured
• The condition resolved
• Later symptoms are unrelated
• The patient failed to reduce the harm
• Additional care was unnecessary
• Another event caused the renewed complaints

There are two common types of gaps.

A Delay Before the First Medical Visit

A person may not seek treatment immediately after an accident. The insurer may argue that a genuinely injured person would have gone to a hospital or doctor at once.

That argument does not account for the many reasons symptoms may not be evaluated immediately. Adrenaline can temporarily mask pain. Inflammation and stiffness may increase over several hours or days. A person may initially believe the condition will improve without treatment.

Other individuals delay care because they lack insurance, cannot afford a deductible, need childcare, cannot miss work, or do not have transportation.

A Break During Ongoing Treatment

A patient may begin treatment and later go weeks or months without another appointment.

Possible explanations include:

• Difficulty obtaining a specialist appointment
• Delayed authorization
• A provider’s scheduling backlog
• Lack of transportation
• Loss of health insurance
• Financial hardship
• Illness or family obligations
• Temporary improvement followed by worsening symptoms
• Instructions to continue treatment at home
• Completion of one treatment phase while awaiting the next

These explanations may be legitimate, but they should be documented whenever possible. A record that simply stops and later resumes can give an adjuster room to characterize the gap in the way most favorable to the insurer.

Why Does Prior Medical History Matter?

When a person claims injury to the neck, back, shoulder, knee, head, or another body part, the insurance company may request earlier records involving the same area.

The insurer is looking for evidence of:

• Similar pain before the accident
• Earlier injuries
• Prior surgery
• Degenerative changes
• Arthritis
• Previous work restrictions
• Earlier imaging findings
• Prior physical therapy
• Chronic medical conditions
• Earlier disability claims

A prior condition does not necessarily mean the accident caused no compensable harm.

An accident can:

• Cause a new injury
• Aggravate an existing condition
• Accelerate symptoms
• Turn an asymptomatic condition into a painful one
• Worsen a previously manageable limitation
• Create the need for treatment that was not previously required

For example, an older MRI may show spinal degeneration even though the person was working, exercising, and living without significant pain before the crash. After the collision, the same person may develop persistent symptoms, require injections, or become unable to perform ordinary activities.

The relevant question is not always whether an abnormality existed before the accident. It may be whether the accident caused a meaningful change in symptoms, function, treatment needs, or prognosis.

How Insurers Use Prior Records Against Claimants

An insurance reviewer may compare old and new medical records line by line.

The insurer may argue that:

• The same diagnosis existed years earlier
• Earlier records mention similar symptoms
• The patient previously injured the same body part
• Current imaging is unchanged
• Surgery had been discussed before the accident
• The patient failed to disclose prior treatment
• The accident caused no measurable difference

Even a brief complaint from many years earlier may be highlighted as evidence of a preexisting condition.

This is why accuracy matters when patients provide their medical histories. Saying “I have never had back pain” can damage credibility if an old record documents a prior episode. A more accurate explanation might be that there was a temporary episode years earlier that resolved and did not limit daily activity before the current accident.

Incomplete memory is common, especially when a person is asked to recall years of medical treatment. Nevertheless, inconsistencies can be portrayed as intentional concealment. A careful review of relevant prior history can help prevent avoidable disputes.

What Is Selective Interpretation of Medical Records?

A medical chart can contain hundreds of entries written by different providers for different purposes. The record may include pain scores, examinations, treatment plans, billing codes, medication lists, copied text, diagnostic impressions, and brief statements about daily functioning.

Selective interpretation occurs when an insurer emphasizes isolated information that supports denial while overlooking the broader medical picture.

Emphasizing Normal Findings

A reviewer might focus on a normal X-ray while minimizing the fact that X-rays do not show every soft-tissue, neurological, or functional injury.

The insurer might also cite:

• Normal strength
• Normal reflexes
• No fracture
• No emergency surgery
• A normal neurological test
• A negative finding during one appointment

Those findings may be relevant, but they do not necessarily prove that the person had no injury or pain.

Ignoring Abnormal Findings

At the same time, the review may give little weight to:

• Muscle spasms
• Reduced range of motion
• Tenderness
• Positive orthopedic tests
• Disc abnormalities
• Nerve symptoms
• Repeated pain complaints
• Failed conservative treatment
• Specialist recommendations
• Work restrictions

A fair analysis should consider favorable and unfavorable findings together.

Treating Improvement as Full Recovery

Medical records frequently use terms such as “improving,” “better,” or “responding to treatment.”

An insurer may portray these phrases as proof of complete recovery. In reality, a patient can improve from severe pain to moderate pain and still have substantial limitations.

The surrounding note may show that the person continued to experience:

• Difficulty sleeping
• Reduced lifting capacity
• Pain while driving
• Limited standing or walking
• Inability to return to work
• Restricted recreational activity
• Need for medication or additional treatment

One positive phrase should not necessarily be separated from the remainder of the record.

Using Silence as Proof

A medical note may not mention every symptom at every visit. An orthopedic appointment focused on a knee injury may say little about headaches. A primary-care visit concerning medication may not restate every physical limitation.

An insurer may argue that an omitted symptom had resolved. But medical notes are not always comprehensive transcripts. The significance of an omission depends on the purpose of the visit, the provider’s documentation practices, and the rest of the record.

Can Minor Inconsistencies Be Used Against an Injury Claim?

Medical records may contain inconsistencies involving:

• The date symptoms began
• Which side of the body hurts
• Pain levels
• Whether a patient lost consciousness
• The accident mechanism
• Prior medical history
• Activity limitations
• Improvement between visits

Some inconsistencies are significant. Others result from hurried intake forms, dictation errors, copied text, translation issues, memory problems, or differences in how medical providers ask questions.

An insurer may collect these variations and characterize them as evidence that the claimant is unreliable.

For example, one record might describe pain as seven out of ten, while another records it as four out of ten. That difference may simply reflect changing symptoms, medication effects, or a good day versus a bad day. It does not automatically mean the person is exaggerating.

The complete timeline matters more than any isolated entry.

How Do Insurance Companies Dispute Causation?

Causation is often the central issue in a medical-record review.

The insurer may accept that a medical condition exists but dispute that the accident caused it.

Common arguments include:

• The condition is degenerative
• The injury resulted from aging
• Symptoms predated the accident
• The accident was too minor to cause the diagnosis
• There was no immediate complaint
• Imaging does not show an acute injury
• A later incident interrupted the causal chain
• Treatment began too late
• The provider relied only on the patient’s account

A reviewer may also distinguish between radiological findings and symptoms. For example, the report may state that an MRI abnormality appears chronic rather than acute.

That does not necessarily end the inquiry. A preexisting structural condition may have been asymptomatic or manageable before the accident and disabling afterward. Medical causation may require consideration of the patient’s prior functioning, symptom onset, examination findings, treatment response, and expert opinions—not simply the age of an imaging abnormality.

How Do Insurers Challenge the Amount of Treatment?

Even when an insurer accepts that an accident caused some injury, it may dispute the duration, frequency, or cost of treatment.

An insurer might acknowledge a temporary strain but refuse to accept:

• Months of physical therapy
• Chiropractic treatment
• Pain-management procedures
• Diagnostic injections
• Surgery
• Future medical care
• Long-term medication
• Permanent work restrictions

A reviewing physician may rely on generalized recovery timelines or treatment guidelines. The report may conclude that a typical injury should have resolved within a certain period.

Individual patients do not always recover according to averages. Age, injury severity, occupation, preexisting vulnerability, delayed diagnosis, complications, and response to treatment may all affect recovery.

The opinions of treating providers may be particularly important because those professionals observed the patient over time, monitored progress, and adjusted treatment based on actual response.

Should You Sign a Broad Medical Authorization?

An insurance adjuster may ask an injured person to sign a broad authorization allowing the insurer to obtain medical records.

The request may extend far beyond the treatment directly related to the accident. It could potentially reach years of primary-care, mental-health, prescription, reproductive-health, or unrelated specialist records.

Some prior records may be relevant, particularly when the claimant had a similar earlier injury. That does not necessarily mean the insurance company should receive unrestricted access to the person’s entire medical history.

Before signing a broad release, an injured person may benefit from understanding:

• Which providers are covered
• What date range is included
• Whether the authorization permits continuing access
• Whether unrelated medical information may be disclosed
• Whether records can be obtained through a more limited request
• How the insurer intends to use the information

Once a personal injury claim places physical or mental conditions at issue, some medical information may be discoverable. The proper scope, however, depends on the issues in the case and the applicable legal procedures.

How Can Injured People Protect the Accuracy of Their Medical Records?

Patients cannot control every chart entry, but they can take reasonable steps to improve the accuracy and consistency of the medical history.

Give Providers an Accurate History

Explain:

• When symptoms began
• How the accident occurred
• Which activities are difficult
• Whether symptoms are constant or intermittent
• What makes the condition better or worse
• Whether similar symptoms existed before
• Whether another event affected the injury

Do not exaggerate, but do not minimize symptoms either.

Attend Recommended Appointments

Following the treatment plan can demonstrate that the injury is being taken seriously. When an appointment must be missed, reschedule it and explain significant barriers to the provider.

Discuss Treatment Gaps

Tell the provider when care was interrupted by cost, scheduling, transportation, insurance issues, family responsibilities, or temporary improvement.

Report Functional Limitations

Pain numbers alone may not communicate the impact of an injury. Explain specific limitations, such as difficulty:

• Sitting through a workday
• Carrying groceries
• Sleeping
• Driving
• Climbing stairs
• Caring for children
• Exercising
• Performing household tasks

Correct Meaningful Errors

Patients may ask providers about correcting material inaccuracies in their records. A correction should not involve rewriting an unfavorable but accurate history. It may be appropriate when the chart lists the wrong body part, accident date, prior condition, or other factual information.

Preserve Medical Documents

Keep copies of:

• Discharge instructions
• Referrals
• Work notes
• Prescription information
• Imaging reports
• Appointment records
• Bills
• Insurance correspondence
• Denial notices

These materials can help establish the full treatment timeline.

How Can a Personal Injury Attorney Respond to a Medical Record Review?

A California personal injury attorney may evaluate whether the insurer’s review accurately reflects the complete record.

Depending on the case, the attorney may:

• Obtain the full medical file
• Compare the review with the records actually cited
• Identify omitted findings
• Review prior medical history
• Explain treatment gaps
• Obtain statements from treating physicians
• Challenge misleading recovery timelines
• Compare pre-accident and post-accident functioning
• Question the reviewer’s specialty and qualifications
• Examine how frequently the reviewer works for insurers
• Take the reviewer’s deposition
• Obtain an additional expert opinion
• Present testimony about daily limitations
• Challenge the scope or conditions of a defense medical examination

When a physical examination is demanded during California litigation, state procedural law provides rules governing the examination. The specific rights and procedures depend on the type of examination and the circumstances of the case.

An attorney can also help distinguish between a reasonable medical disagreement and a report that selectively interprets records to support a predetermined claims position.

A Medical Review Is an Opinion, Not the Final Word

Insurance companies often present medical reviews as definitive conclusions. However, an independent medical examination, peer review, or utilization review remains an evaluation prepared for a particular purpose.

The strength of that evaluation may depend on:

• Whether the reviewer examined the patient
• Whether the reviewer saw the complete record
• Whether the reviewer practices in the relevant specialty
• Whether the report addresses contrary evidence
• Whether conclusions are supported by medical reasoning
• Whether the reviewer considered the patient’s prior level of function
• Whether the report accurately describes the treatment timeline
• Whether important findings were omitted

A treating physician and an insurer-retained reviewer may reach different conclusions from the same information. When that happens, the claim must be evaluated using the entire evidentiary record rather than whichever isolated opinion favors the insurance company.
