What Is a Claims Adjuster? (And How They Affect Your Payout)
Learn what a claims adjuster does, the types of adjusters you may encounter, how their decisions affect your insurance payout, and how to push back when they undervalue your claim.
What Is a Claims Adjuster?
A claims adjuster — also called a claims examiner or claims analyst — is a professional who investigates, evaluates, and settles insurance claims on behalf of an insurance company. When you submit a claim, a claims adjuster reviews your documentation, assesses the facts of your situation, and determines how much — if anything — the insurer will pay.
In health insurance, claims adjudication is often automated for routine claims, but human adjusters play a significant role when claims are complex, expensive, flagged for review, or disputed.
What Are the Types of Claims Adjusters?
Staff adjuster (inside adjuster) Employed directly by the insurance company. Staff adjusters handle claims day-to-day as salaried employees of the insurer. Their primary loyalty is to their employer, the insurer.
Independent adjuster A contract worker hired by insurers on a per-claim basis, often during high-volume periods such as after natural disasters. Independent adjusters work for an adjustment company, not directly for the insurer, but are paid by the insurer.
Public adjuster A licensed professional hired by — and exclusively representing — the policyholder, not the insurer. Public adjusters help you document losses, prepare claims, and negotiate settlements when you believe the insurer is undervaluing your claim. They typically charge a percentage of the settlement (commonly 5–15%).
Desk adjuster Handles claims remotely — by phone, mail, and electronic records — without inspecting the loss in person. Common for smaller health insurance and property claims.
Field adjuster Visits the site of a loss or meets with the claimant in person to inspect damage or interview witnesses. More common in property, auto, and workers' compensation claims.
What Does a Claims Adjuster Do in Health Insurance?
In health insurance, claims adjudicators and adjusters perform the following functions:
- Verify coverage: Confirm you were enrolled and covered at the time of service
- Apply policy terms: Match the services billed against your plan's coverage, exclusions, and limitations
- Review clinical criteria: For complex or expensive claims, assess whether the services were medically necessary using clinical guidelines (such as InterQual or Milliman)
- Apply cost-sharing: Calculate the portion of the bill allocated to your deductible, coinsurance, and copay
- Identify billing issues: Catch duplicate claims, upcoded procedures, or unbundled charges
- Issue payment or denial: Approve payment to your provider, approve reimbursement to you, or issue a denial with stated reasons
How Do Claims Adjusters Affect Your Payout?
A claims adjuster's decisions directly determine whether your claim is paid, how much is paid, and what you owe out of pocket. Key decision points that affect your payout include:
Medical necessity determinations If an adjuster — or the clinical reviewer supporting the adjuster — determines a service was not medically necessary, the claim will be denied. This is the most commonly contested type of denial.
Usual, Customary, and Reasonable (UCR) rates For out-of-network claims, the adjuster applies UCR rates to determine how much the insurer considers a "reasonable" charge for the service. UCR rates vary widely by database and region, and using an outdated or low database can significantly reduce your reimbursement.

Bundling and unbundling decisions Adjusters may "bundle" separately billed services into a single payment code (reducing the total paid), or conversely may dispute "unbundling" by a provider.
Coordination of benefits When you have multiple insurance plans, the adjuster determines which plan is primary and applies coordination rules.
What Can You Do If a Claims Adjuster Undervalues or Denies Your Claim?
1. Request a detailed written explanation. You have the right to know the specific basis for any denial or reduced payment. The adjuster must provide the policy provision, clinical criteria, or calculation methodology used.
2. Request your complete claims file. Under federal law, you can request all documents, records, and guidelines used in the claims decision. This often reveals whether proper procedures were followed.
3. File an internal appeal. You can challenge the adjuster's decision through your insurer's formal appeal process. Your appeal will be reviewed by different personnel — typically including a medical director for clinical denials.
4. Hire a public adjuster (for property claims). For property and casualty claims (not health insurance), a licensed public adjuster can negotiate with the insurer on your behalf and often obtains higher settlements.
5. Request an External Independent Review: Complete Guide" class="auto-link">external review (for health insurance). After exhausting internal appeals, you can request an independent external review by a neutral third party whose decision is binding on the insurer.
6. File a complaint with your state insurance department. If you believe the adjuster handled your claim in bad faith — including unreasonable denial, excessive delay, or misrepresentation of your policy — file a formal complaint with your state insurance commissioner.
Can an Adjuster's Decision Be Wrong?
Yes — frequently. Adjusters work under significant volume pressure and apply policy terms and clinical criteria that may be interpreted incorrectly. Common adjuster errors include:
- Applying the wrong clinical guideline or an outdated version
- Failing to consider all relevant medical records
- Misidentifying a service code
- Incorrectly applying a policy exclusion
- Using an incorrect UCR database rate
These errors are exactly what appeals are designed to correct.
