Insurance companies evaluate injury claims by comparing the available evidence with the policy language, applicable law, and the losses being requested. The review usually focuses on four questions: Did the incident occur as reported? Is the claimed injury connected to it? Is the treatment and financial loss reasonable and documented? What amount, if any, does the policy require the insurer to pay?
The process can apply to vehicle crashes, premises incidents, dog bites, and other injury claims. Each type of claim has different rules, but the basic evaluation methods are similar.
What information does an insurance company examine first?
An insurer begins by gathering facts about the incident and identifying which policy or policies may apply. A claim file may include:
- The incident report or police report
- Statements from the people involved and witnesses
- Photographs, video, diagrams, or physical evidence
- Medical records and billing information
- Employment records and proof of lost income
- Insurance policies, exclusions, deductibles, and coverage limits
- Information about previous injuries or medical conditions
The adjuster may also review public records, vehicle damage, weather conditions, property maintenance records, or communications made after the incident. In a densely populated area such as Detroit, traffic-camera footage, nearby security video, building records, and witness accounts may become especially relevant when the event occurred near a busy roadway, apartment building, sidewalk, or commercial property.
The insurer is not simply deciding whether someone was hurt. It is assessing whether the evidence supports the particular claim being made.
How is responsibility evaluated?
Responsibility is usually assessed by reconstructing what happened and comparing the conduct of each person with the applicable legal duty. In a vehicle crash, the insurer may examine traffic signals, lane positions, vehicle damage, witness statements, driver accounts, and available video. In a property case, the review may focus on whether a hazardous condition existed, how long it existed, and whether reasonable steps were taken to address or warn about it.
An adjuster may also ask whether the injured person contributed to the event. Examples could include walking outside an intended path, ignoring a warning, failing to use available safety equipment, or driving in a way that contributed to the collision.
Michigan generally uses comparative fault in personal injury actions. Under Michigan Compiled Laws section 600.2959, damages may be reduced according to the injured person’s percentage of fault. If the injured person’s fault is greater than the combined fault of the other parties, noneconomic damages generally may not be awarded, although economic damages may still be reduced.

An insurance company’s fault assessment is not automatically the final legal decision. It is an initial position based on the evidence available to the insurer.
How does the insurer connect an injury to the incident?
Causation is one of the most closely examined parts of a claim. The insurer may compare:
- The person’s symptoms immediately after the event
- The timing of the first medical visit
- Diagnoses and test results
- Statements made to medical providers
- The treatment plan and treatment gaps
- Prior medical records
- Whether the claimed condition is consistent with the reported mechanism of injury
A short delay in treatment does not necessarily prove that an injury is unrelated. People may initially believe pain will improve, lack transportation, have difficulty taking time away from work, or not recognize the seriousness of an injury. However, delays and unexplained gaps may lead an insurer to question whether all treatment resulted from the incident.
Preexisting conditions are also not automatically disqualifying. The central question is often whether the event caused a new injury, made an existing condition worse, or had no meaningful connection to the claimed symptoms. Clear medical records are more useful than general descriptions of pain because they show what providers observed, diagnosed, and treated.
What makes medical treatment appear reasonable and necessary?
Insurers review whether the treatment matches the reported injury and whether the services were medically appropriate. They may compare the initial diagnosis with later procedures, referrals, therapy, medication, and specialist care.
Michigan auto claims have an additional layer of review. Personal Protection Insurance, commonly called PIP, generally covers qualifying medical expenses and certain other benefits without regard to fault, subject to the policy’s coverage selection and legal requirements. Michigan law also permits utilization review of medical care for auto-injury claims to determine whether treatment meets applicable standards of medical appropriateness. ([legislature.mi.gov](https://legislature.mi.gov/Laws/MCL?highlight=house&objectName=mcl-218-1956-31&utm_source=openai))
This means a person may have a legitimate injury while still facing a dispute about whether a specific treatment, charge, duration of care, or billing amount should be paid.
How are lost wages and other financial losses checked?
Economic losses are evaluated through records rather than estimates alone. Common documentation includes:
- Pay stubs and payroll histories
- Employer statements
- Tax records for self-employed workers
- Work restrictions from medical providers
- Attendance records
- Receipts for replacement services or necessary expenses
- Bills, payment records, and insurance explanations of benefits

The insurer may ask whether the claimed time away from work matches the medical restrictions. A person who returned to modified duties may have a partial wage-loss claim rather than a claim for complete inability to work. For household services, the insurer may examine what tasks were needed, why assistance was medically necessary, and whether the charges are supported.
In Michigan auto cases, PIP benefits can include wage loss and replacement services, but limits and time restrictions apply. The policy and the facts of the claim determine what is available.

Why does the policy itself matter so much?
Coverage comes before valuation. An insurer may agree that an incident happened and that an injury is genuine but still dispute whether a particular policy covers the loss.
The adjuster may review:
- Who was insured
- Whether the policy was active on the date of the incident
- Definitions of covered losses
- Exclusions and conditions
- Policy limits
- Other available insurance
- Notice and proof-of-loss requirements
For auto-related injuries, Michigan’s no-fault system distinguishes between first-party benefits, such as PIP, and claims against another person for certain noneconomic or excess losses. A person’s eligibility can depend on whether the person was an occupant of a vehicle, a pedestrian, a cyclist, or otherwise covered under a particular policy arrangement. Michigan law includes specific rules for people injured while not occupying a motor vehicle.

What can make an insurer question a claim?
Questions commonly arise when records contain inconsistencies or missing information. Examples include different descriptions of how the incident occurred, medical histories that do not mention the event, unexplained treatment gaps, unusually delayed reporting, or bills that do not match the treatment records.
A recorded statement can also become part of the claim file. Answers that are uncertain, incomplete, or based on guesswork may later be compared with medical records or witness accounts. It is generally safer to provide accurate information, distinguish what is known from what is uncertain, and avoid speculating about legal responsibility or the full extent of future recovery.
A social media post does not automatically defeat a claim, but photographs or statements that appear inconsistent with claimed limitations may be reviewed. Everyday activity does not necessarily mean a person is fully recovered; context matters.
What should Detroit residents keep after an injury?
A well-organized record can make the evaluation more accurate. Keep copies of medical records, bills, prescriptions, work restrictions, wage documentation, photographs, incident reports, insurance correspondence, and a dated symptom journal.
For a vehicle incident, preserve photographs of the scene and damage if safely possible. Seasonal conditions such as snow, ice, potholes, reduced visibility, and wet pavement may be relevant, but they do not by themselves establish fault. The insurer will still examine notice, maintenance, driver conduct, warnings, and the specific conditions at the time.
Michigan’s Department of Insurance and Financial Services states that an auto insurer must explain within 30 days what information is needed to handle a reported loss and must pay portions supported by satisfactory documentation. Certain overdue PIP payments may accrue interest under state law. ([michigan.gov](https://www.michigan.gov/autoinsurance/choosing-coverage/consumer-rights?utm_source=openai))
An insurer’s evaluation is a claims position, not a guaranteed measure of the injury’s legal value. Coverage language, medical evidence, responsibility, financial documentation, and Michigan’s specific rules all affect the result.
