What Does an Insurance Adjuster Do After a Car Accident?

When you file a claim after a motor vehicle accident, the person assigned to evaluate it is called an insurance adjuster. Understanding what adjusters do — and who they work for — helps clarify why the claims process unfolds the way it does.

The Adjuster's Core Job

An insurance adjuster investigates claims to determine what happened, who was responsible, and how much the insurer should pay. That sounds straightforward, but the role involves several distinct tasks:

• Gathering facts — reviewing the police report, interviewing involved parties and witnesses, and sometimes visiting the accident scene
• Assessing vehicle damage — inspecting your car directly or reviewing estimates from a repair shop; some insurers use photo-based or virtual appraisals
• Reviewing medical records and bills — evaluating injury claims by examining treatment records, provider invoices, and documentation of ongoing care
• Determining fault and liability — applying the relevant state's rules to decide how responsibility is allocated between the parties
• Calculating a settlement value — factoring in property damage, medical expenses, lost wages, and sometimes pain and suffering

The adjuster's findings directly shape the settlement offer you receive.

First-Party vs. Third-Party Adjusters

One of the most important distinctions in any claim is who the adjuster works for.

A third-party adjuster is employed by — and works in the interest of — the opposing driver's insurer, not yours. That doesn't mean they act in bad faith, but their job is to evaluate claims on behalf of their employer.

How Fault Determination Works

Adjusters don't operate in a vacuum. They apply state law when assigning fault, and those rules vary significantly.

In at-fault states, the at-fault driver's liability insurance is generally responsible for damages. In no-fault states, each driver's own Personal Injury Protection (PIP) coverage pays for their medical expenses regardless of who caused the crash — though serious injuries may still allow a claim against the at-fault driver depending on whether a tort threshold is met.

Fault allocation itself also varies:

• Pure comparative negligence — you can recover damages even if you were mostly at fault, reduced by your percentage of responsibility
• Modified comparative negligence — recovery is only allowed if your fault falls below a certain threshold (commonly 50% or 51%)
• Contributory negligence — in a small number of states, any fault on your part can bar recovery entirely

The adjuster applies whichever standard governs in your state. That determination affects not just whether you receive payment, but how much.

What Adjusters Look At When Evaluating Injury Claims

For property damage, valuation is relatively formulaic — repair costs, actual cash value, and depreciation. Injury claims involve more judgment. Adjusters typically review:

• Emergency room and hospital records
• Follow-up treatment documentation — physical therapy, specialist visits, imaging
• Lost wage verification — employer statements, pay stubs, tax records
• Proof of ongoing symptoms or permanent impairment

🗂️ Gaps in treatment — periods where a claimant didn't seek care — are often scrutinized. Adjusters may argue that a gap suggests the injury wasn't serious or wasn't caused by the accident. Whether that argument holds up depends heavily on the facts and, in some cases, how the claim is presented.

When Attorneys Become Part of the Equation

Once an attorney is involved, communication with the claimant typically shifts. The adjuster negotiates directly with the attorney rather than the claimant. Attorneys often send a demand letter — a formal document outlining the injuries, treatment, damages, and a requested settlement amount — which the adjuster reviews and responds to.

Attorney involvement often changes the dynamics of settlement discussions. Whether that works in a claimant's favor depends on the complexity of the case, the severity of injuries, and the specific facts involved.

What the Adjuster Cannot Determine for You

Adjusters evaluate claims — they don't decide your legal rights. Several things fall outside their authority:

• Whether you have a viable legal claim under your state's law
• What your case might be worth if it went to court
• Whether your insurer's coverage interpretation is correct or disputable
• How a judge or jury might evaluate disputed facts

⚖️ Coverage disputes, denied claims, and disagreements over fault percentages are all situations where the adjuster's decision isn't necessarily final. Policies include appeal and appraisal processes, and state insurance commissioners oversee insurer conduct.

The Variables That Shape Your Outcome

How an adjuster handles your claim — and what you ultimately receive — depends on factors no general explanation can account for:

• Which state the accident occurred in and what fault rules apply
• Whether you're dealing with your own insurer or the other driver's
• The type and amount of coverage available on both sides
• The nature and documentation of your injuries
• Whether attorney representation is involved
• The specific language of your policy

The adjuster's role is consistent across claims. The results are not.
