Independent medical exams and injury bill audits

An "independent" medical examination is an exam by a doctor the insurer selects and pays, who answers questions the insurer needs answered: what the injury is, whether the crash caused it, and whether the treatment so far is reasonable and necessary. A bill audit is a separate check that compares what a provider charged with what the law or the local market treats as a reasonable price. Together they are the main tools for finding padded injury claims, and they also trim honest ones.

Being sent to an exam or seeing a bill cut does not mean anyone suspects you of fraud. It means a benefit is being tested against a standard, and the standard, the procedure and your options depend on which coverage is paying and which state you are in. This article explains the tools, the authority behind them, claimants' rights where we could read the law, and how disputes are resolved. For the letter that ends no-fault benefits, see PIP and MedPay benefit cutoffs after an independent medical exam.

Four tools that get lumped together

The first three often arrive together, and a benefit cutoff may rest on all of them. The fourth is covered in the cooperation clause: records, interviews and exams under oath and recorded statements: when to give one and when to wait.

Why insurers use them: the padded-claim problem

Auto insurance fraud is not only staged crashes. The Insurance Information Institute (Triple-I) lists padding, meaning inflating a claim, misrepresenting facts and claiming injuries that never occurred among the common frauds, and it notes that in many no-fault states, unscrupulous medical providers, attorneys and others pad costs associated with legitimate claims, for example by billing for a procedure never performed. Its list of common health care fraud types, drawn from the FBI, adds services billed but not rendered, upcoding (billing a code that pays more than the service provided), duplicate claims, unbundling and excessive or unnecessary services.

An injury claim is built from three things that can each be inflated: the diagnosis, the amount of treatment, and the price charged. The exam checks the first two; the audit checks the third.

Two real cases show why insurers look at the structure of treatment, not just the crash:

• In a New York case decided on March 29, 2005, State Farm v. Mallela, State Farm alleged that people who were not physicians had set up medical corporations through paid nominal owners and routed profits through inflated management-company bills. The state's high court held that insurers may withhold payment from fraudulently incorporated medical corporations. The opinion notes that State Farm never alleged the patients received unnecessary care, which shows that some bill disputes concern who is billing, not what treatment was given.
• In Louisiana's staged-crash prosecutions known as Operation Sideswipe, the Associated Press reported in April 2022 that two defendants underwent extensive medical treatment, including neck and back surgeries, because they understood more treatment would increase the value of their lawsuit. That incentive, treatment that tracks the claim's value rather than the patient's condition, is what exams and audits are meant to catch. The case is followed through in how an insurance fraud case is prosecuted from referral to sentence.

Most exams involve no fraud at all: an adjuster unsure whether a surgery relates to a crash 14 months ago orders the same exam as one chasing a ring.

Where the power to require an exam comes from

Nobody can compel a medical exam without a legal basis. Four exist, and which applies depends on your claim.

The ISO language comes from the December 2014 edition of the personal auto policy as reprinted by PropertyCasualty360, whose commentary adds that a third-party claimant has no obligation to submit to any examination except voluntarily in a negotiated settlement. That matters if you were hit and are claiming against the other driver's insurer: it can ask, but cannot require an exam without a court order in litigation. If you claim under your own medical payments, PIP or uninsured motorist coverage, the policy duty applies. Your policy may differ from the ISO form, so read it.

The statutory examples show how states fill in the details:

• Florida PIP. Section 627.736(7) requires an injured person to submit, on the insurer's request, to a mental or physical exam when the condition is material to a claim. The insurer bears the cost, and the exam must be in the municipality where the person is treated or in a location reasonably accessible to the person, which the statute defines by municipality or by 10 miles by road from the residence within the same county.
• Michigan PIP. MCL 500.3151 requires a person whose condition is material to a claim for personal protection insurance benefits to submit to an exam by physicians at the insurer's request, and sets the examiner's qualifications.
• New York no-fault. 11 NYCRR 65-3.5 provides that if the extra verification the insurer wants is a medical exam, it must schedule the exam to be held within 30 calendar days of receiving the prescribed verification forms.
• Federal lawsuits. Rule 35 lets a court order a party whose condition is in controversy to be examined, only on motion for good cause, with the time, place, manner, conditions, scope and examiner specified.

Who chooses and pays the doctor, and what limits apply

"Independent" describes the doctor's professional role, not who hired them. The insurer picks the examiner and pays; the law adds guardrails.

• Cost. The Florida statute puts the cost of insurer-requested exams entirely on the insurer. The ISO form says "at our expense." In New York, the insurer must tell you when scheduling that you will be reimbursed for lost earnings and reasonable transportation expenses, and the exam must be at a place and time reasonably convenient to you in a properly equipped facility.
• Qualifications. Michigan requires the examiner to share the specialty of a treating specialist (and be board certified if the treating doctor is) and to have spent a majority of the prior year in clinical practice or teaching. Florida requires a report used to withdraw payment from a treating physician to come from a Florida physician licensed under the same chapter, in active practice.
• Independence. Under the Florida PIP statute, an insurer or anyone acting for it may not materially change an opinion in an exam report or direct the physician to change it. The statute allows the insurer to point out errors of fact based on the claim file. A separate Florida fraud statute, 817.234, makes violating that rule a third-degree felony. Exam doctors and anyone offering expert opinions on behalf of claimants must keep copies of reports and records of payments for at least three years.

Peer review and records reviews

Not every dispute needs a body in an exam room. In a records review, a physician reads the file and writes an opinion.

Pennsylvania builds this into its statute. Under 75 Pa.C.S. 1797, insurers contract with a peer review organization (PRO) to evaluate whether treatment conforms to professional standards and is medically necessary. An insurer must make its challenge to the PRO within 90 days of receiving the bill (or at any time for continuing treatment). The insurer, provider or insured can request reconsideration within 30 days, and if a physician's services are reviewed, the reviewer must be, or the panel include, someone in the same specialty. If the insurer challenges within 30 days of receiving a bill, it need not pay until the PRO decides, and the insured may not be billed for the services during peer review. If the PRO finds the treatment medically necessary, the insurer pays plus 12 percent annual interest on withheld amounts.

Other states are less structured. New York requires that when the specific reason for a denial is a medical examination or peer review report the insurer requested, it must release a copy of that report to the applicant, the applicant's attorney or the treating physician on written request.

The standard these reviews apply is nearly the same everywhere: was the treatment reasonable, related to the accident, and necessary? Florida's statute frames it as "reasonable, related, or necessary"; Pennsylvania's as conforming to professional standards and medically necessary; Michigan's as "reasonably necessary" products and services. ISO medical payments coverage pays reasonable expenses incurred for necessary medical and funeral services caused by accident, within three years of the accident.

Bill audits: usual and customary charges and fee schedules

A bill audit asks whether the price is reasonable. Statutes answer that question two ways.

Customary charge limits. Michigan's MCL 500.3157 lets a provider charge a reasonable amount that does not exceed what the provider customarily charges for like treatment in cases that do not involve insurance. That sentence is the idea behind "usual and customary" audits: your auto-claim bill should not be higher than the same provider's everyday price.

Fee schedules. Many no-fault states tie payment to a percentage of Medicare. Michigan caps most providers at 190 percent of the Medicare amount for treatment after July 1, 2023, with higher caps for certain providers. Florida lets insurers limit PIP reimbursement to 80 percent of a schedule of maximum charges that is generally 200 percent of Medicare Part B for most services. Pennsylvania's rule caps charges at 110 percent of the applicable Medicare amounts or the provider's usual and customary charge, whichever is less.

What a reduction looks like in numbers

This is a hypothetical with invented figures and a Florida-style rule.

Say a clinic bills $140 for a service that Medicare Part B allows at $52 in your area.

1. 200 percent of the Medicare amount is $104.
2. The insurer may limit reimbursement to 80 percent of that: $83.20.
3. The "cut" is $140 minus what was paid. It is a billing adjustment, not a finding that you did anything wrong.

When an insurer pays less than billed or rejects part of a PIP claim in Florida, the statute requires it to give, at the time, an itemized specification of each item it reduced, omitted or declined, along with any information it wants the claimant to consider about necessity or reasonableness, and a contact name, address and claim number.

Causation and pre-existing conditions

Whether the crash caused the injury is often the heart of the disagreement. Examiners compare three things: what the records show before the accident, what the records show after, and whether the mechanism of the crash plausibly explains the new findings.

A pre-existing condition does not by itself end a claim; the usual question is whether the crash caused a new injury or made an old one worse. An examiner who writes "degenerative changes unrelated to the accident" is making a medical judgment your treating physician's records can challenge.

The single most damaging thing an honest claimant can do is leave out prior treatment. A doctor who sees only a clean history will build a causation opinion on it, and a later discovery of old records shifts the dispute from medicine to credibility. Tell every provider and the examiner about prior problems with the same body part, even minor ones. injuries that show up days after a crash: protecting your claim covers why symptoms sometimes appear days later.

What you can ask for, and what refusing risks

You are entitled to know more than the notice letter says. Before the exam, ask in writing for:

• The date, time and address, and whether it fits your state's convenience rules.
• The doctor's name and specialty, and why that specialty applies to your injury.
• What the exam will cover, and whether it includes testing or imaging.
• Confirmation that you will be reimbursed for lost earnings and travel, if your state provides that.
• A copy of the report afterward.

On the report, Florida says that if the person examined requests it, the party causing the exam must deliver a copy of every written report, one of which must set out the findings and conclusions in detail, and then the insurer may request your reports of other exams for the same condition. Federal Rule 35 contains a similar exchange. New York releases insurer-requested exam reports on written request when they are the reason for a denial.

Whether you can bring a companion, a lawyer or a recording device varies by state, insurer and examiner. Ask in writing before the day and keep the answer.

Refusing is the riskier path. Florida's statute says that if a person unreasonably refuses to attend or fails to appear, the PIP carrier is no longer liable for subsequent PIP benefits, and refusing or failing to appear twice raises a rebuttable presumption that the refusal was unreasonable. If you have a genuine conflict, reschedule promptly and in writing. Other states use policy language and case law instead of a single rule, and the ISO form qualifies the insured's duties by prejudice to the insurer. Do not rely on that as a safe harbor.

A worked example

This is invented, to show the sequence.

Say you were rear-ended in March, and your own PIP coverage has paid for physical therapy and a chiropractor for four months. In July, the insurer writes that it has scheduled an exam for August 4.

1. Day 1. You email the adjuster: "Please confirm the doctor's name and specialty, the address, and whether my lost earnings and transportation will be reimbursed. Please also confirm I will receive a copy of the report."
2. Day 3. You ask your treating doctor's office for a copy of your records and whether the doctor will write a letter on necessity before the exam.
3. Exam day. You list prior neck problems, a minor strain from five years ago, accurately. You describe symptoms in everyday terms, not in the vocabulary of a lawsuit. You keep notes: how long the exam lasted, what was tested.
4. Two weeks later. A letter says benefits for therapy are cut off because the examiner found the treatment no longer necessary. The letter attaches a bill audit that also reduces two earlier chiropractic charges.
5. Response. You request the full report, ask your doctor to rebut it in writing, and look up your state's dispute process.

Nothing in this sequence involved an accusation. If the examiner's opinion is wrong, the treating doctor's records are how you show it.

How disputes are resolved

Where the exam or audit produces a denial, the dispute moves through whichever system your coverage provides.

• New York no-fault. The Insurance Law directs simplified arbitration of no-fault disputes. Under 11 NYCRR 65-4.2, an applicant can start by mailing the denial of claim form, with the reasons for contesting it and a listing of the expenses in dispute, to the designated administering organization. The regulation text read in November 2026 lists a $40 filing fee, returned by the insurer if the applicant prevails in whole or in part. Some of that detail changes, so check the current forms.
• Florida PIP. A demand letter is a condition of a lawsuit under section 627.736(10). If the insurer pays the overdue claim with interest and a 10 percent penalty (maximum $250) within 30 days of the notice, no suit may be brought.
• Pennsylvania. Peer review reconsideration, then court; the statute provides for treble damages for wanton conduct.
• Medical payments coverage. The statutes read did not provide a special process for med-pay disputes. It is a first-party contract claim: you complain to the insurer, then to the department of insurance, and a lawyer can advise on a suit. See Medical payments coverage (MedPay) explained. The coverage's three-year window for incurred expenses is in the policy language quoted above.

For general dispute tools, see arbitration and mediation in auto insurance disputes. A licensed attorney or the state insurance department can give specifics for your state, and the state car insurance requirements lookup tool shows whether your state is no-fault.

Common questions

Does an IME mean the insurer thinks I'm committing fraud?

Not usually. An exam is a routine way to resolve questions about causation and treatment. Fraud work is done by a different unit; see My claim is under SIU review: what to expect and your rights. The two can overlap when a claim shows other red flags, but an exam is not an accusation.

Can the at-fault driver's insurer make me go to an exam?

Only through a court order in litigation (for example under Rule 35 in federal court or a state equivalent) or an agreement. The commentary on the ISO form states that a third-party claimant has no obligation to submit to an examination except voluntarily as part of a negotiated settlement.

Can I get the report?

Often yes, and sometimes on request. Florida and New York have provisions delivering the report, as noted above. In states without a specific rule, ask in writing; in litigation, the exchange rules apply.

Key takeaways

• An IME is an exam by a doctor the insurer chooses and pays; a records or peer review is a doctor's opinion without an exam; a bill audit compares charges with fee schedules or customary charges. They are the standard tools for testing padded claims.
• The authority to require an exam comes from your policy, a no-fault statute, a court order or an agreement; a third-party claimant generally cannot be forced without a lawsuit.
• Honest claimants are protected by rules on cost, location, qualifications, report copies and itemized explanations of reductions, which vary by state.
• Disclose all prior injuries, attend the exam, ask for the report, and have your treating doctor respond in writing; unreasonable refusal can end PIP benefits in Florida.
• Disputes go to arbitration, a demand letter, peer review or court depending on the state; an attorney or the insurance department can advise on yours.
