An insurance adjuster is the person on the other side of your personal injury claim. They work for the insurer — not for you. Their job is to investigate the claim, evaluate liability and damages, set a reserve (the insurer's estimated cost), and negotiate a settlement within a pre-approved authority range. Understanding how adjusters work, what tools they use, and what drives their decisions gives you a material advantage in any settlement negotiation.

TL;DR.

Adjusters evaluate claims using internal software (Colossus, Claims Outcome Advisor), published guidelines (JCG, PIAG, Baremo), and comparable settlement databases. They work to a settlement authority — a range within which they can close the file without committee approval. Initial counter-offers run 30–50% below final settlement. Adjusters are not your adversary, but their incentive is to resolve at the lowest defensible cost.

The adjuster's role in the claims process

The adjuster is the insurer's front-line decision-maker. They are responsible for the entire lifecycle of a claim: acknowledging the report, investigating the facts, assessing liability, evaluating damages, setting the reserve, negotiating with the claimant or their representative, and closing the file.

Adjusters handle between 100 and 200 open files at any given time. This is important context: they allocate time based on the apparent complexity and exposure of each claim. A well-documented, clearly presented claim gets more attention — and a more thoughtful evaluation — than a disorganised one.

The claims workflow: step by step

  1. Claim reported and acknowledged. The adjuster receives the first notice of loss (FNOL), confirms coverage under the policy, and assigns a claim number.
  2. Investigation. The adjuster reviews the police report, interviews the parties and witnesses, examines photographs, and assesses liability. In disputed cases, scene investigation or accident reconstruction may follow.
  3. Reserve set. Based on initial information, the adjuster sets a reserve — the insurer's estimate of the total cost to close the file. The reserve is reviewed and adjusted as new evidence emerges.
  4. Medical records reviewed. The adjuster obtains and reviews all medical records, treatment notes, imaging, and specialist reports. They may request an independent medical examination (IME) if the claimed injuries appear disproportionate.
  5. Valuation. The adjuster runs the claim through valuation software (Colossus, Claims Outcome Advisor) and benchmarks against comparable settlements and published guidelines.
  6. Settlement authority obtained. The adjuster requests settlement authority from their supervisor or committee — a pre-approved range within which they can settle without further escalation.
  7. Negotiation. The adjuster responds to the demand letter with a counter-offer and negotiates through a series of exchanges until agreement or impasse.
  8. Settlement or escalation. If the parties agree, the adjuster processes the settlement agreement and payment. If they cannot agree, the file is escalated to defence counsel for litigation.

How reserves are set

The reserve is the insurer's internal estimate of the total cost of a claim. It includes the expected settlement or judgment amount, defence legal fees, adjusting expenses, and any other costs. The reserve is not disclosed to the claimant — it is an internal accounting and risk-management tool.

Reserves matter because they influence settlement authority. An adjuster whose reserve is $75,000 is unlikely to receive authority to settle at $150,000 without substantial new information justifying the increase. Providing strong documentation early in the process helps ensure the reserve is set at an appropriate level.

💡
TipSend medical records and documentation proactively — do not wait for the adjuster to request them. Early, comprehensive documentation drives a higher initial reserve, which supports a higher settlement authority.

Valuation tools and software

Modern adjusters do not value claims on instinct alone. Major US insurers use algorithmic tools that weight diagnosis codes, treatment types, duration, and comparable settlements to produce a recommended range.

Common adjuster negotiation tactics

  • Early low offer. An offer before you have reached maximum medical improvement, hoping you accept before the full value of the claim is known.
  • Requesting excessive documentation. Slowing the process by requesting records that are marginally relevant, creating frustration and pressure to settle.
  • Disputing causation. Arguing that the injury was pre-existing or not caused by the incident in question.
  • Highlighting treatment gaps. Periods without medical treatment are presented as evidence that the injury was not severe.
  • Using the recorded statement. Inconsistencies between your recorded statement and medical records are used to challenge credibility.
  • Splitting liability. Assigning a percentage of fault to the claimant to reduce the payout under comparative fault rules.

Red flags the adjuster looks for

Adjusters are trained to identify indicators that a claim may be inflated or fraudulent. These red flags do not mean fraud exists — but they trigger closer scrutiny:

  • Late-reported claims (filed weeks or months after the incident)
  • Treatment with providers known for inflated billing
  • Symptom descriptions inconsistent with imaging results
  • Social media activity contradicting claimed limitations
  • Multiple prior claims or a litigation history
  • Claimant-referred treatment (provider recommended by attorney, not GP)

How to strengthen your position

  1. Document everything. Medical records, receipts, photographs, employer statements. The adjuster cannot dismiss what is evidenced.
  2. Follow treatment plans. Gaps in treatment are used to argue the injury was not severe. Attend every appointment.
  3. Wait for MMI. Do not engage in substantive negotiation until your prognosis is stable.
  4. Anchor to authority. Frame your demand against the same published guidelines the adjuster uses internally.
  5. Be professional. Adjusters respond to organised, evidenced claims — not emotional appeals or threats.
  6. Know your BATNA. Your best alternative to a negotiated agreement is litigation. If the adjuster knows you are prepared to litigate, they adjust their offer accordingly.

Recorded statements: risks and rights

The adjuster may ask for a recorded statement early in the claim. This is standard practice, but it carries risk. Anything you say can be used later to challenge your claim — inconsistencies with medical records, admissions of partial fault, or minimisation of symptoms can all reduce the settlement.

⚠️
WarningYou are generally not legally required to give a recorded statement to the at-fault party's insurer (as distinct from your own insurer, where policy terms may require cooperation). Consult an attorney before agreeing to a recorded statement in any claim involving moderate to severe injury.

Frequently asked questions

What does an insurance adjuster do?
An insurance adjuster investigates, evaluates, and settles insurance claims on behalf of the insurer. In personal injury, the adjuster reviews liability, assesses damages using internal valuation tools and published guidelines, sets a reserve (the insurer's estimated cost of the claim), and negotiates settlement with the claimant or their attorney.
Do insurance adjusters try to lowball claims?
Adjusters work within a settlement authority — a pre-approved range. Their job is to resolve the claim at the lowest defensible cost, not necessarily the lowest possible cost. Initial counter-offers are typically 30–50% below the final settlement figure. This is standard negotiation practice, not bad faith.
Can I negotiate with an insurance adjuster myself?
Yes. For minor, clear-liability claims, self-negotiation is common and can be effective. For moderate to severe injuries, represented claimants statistically achieve higher settlements because the adjuster factors in the cost and risk of litigation.
What is a claims reserve?
A reserve is the insurer's internal estimate of the total cost of a claim — including the expected settlement, legal fees, and adjusting costs. It is set early in the claim and adjusted as new information emerges. The reserve is not disclosed to the claimant.
Should I give a recorded statement to the adjuster?
Exercise caution. In some jurisdictions, cooperation with a reasonable investigation is required under the policy terms. However, anything you say in a recorded statement can be used to reduce your claim. Consult an attorney before giving a detailed recorded statement, especially for moderate to severe injuries.
What software do adjusters use to value claims?
Major US insurers use Colossus, Claims Outcome Advisor, or proprietary algorithms that weight injury diagnosis, treatment, duration, and comparable settlements. UK insurers rely more heavily on the Judicial College Guidelines. These tools produce a recommended range, not a fixed figure — the adjuster retains discretion within their authority.
