IME for Workers’ Comp: What to Expect

An independent medical examination (IME) is one of the most important, and often most misunderstood, steps in a workers’ compensation case. For injured workers, the IME can feel daunting because it involves being examined by a physician who has not provided prior treatment. Understanding exactly what the process involves, what the examining physician evaluates, and how the resulting report is used helps remove uncertainty and allows the examinee to participate fully in the evaluation.

Through Burnham Orthopedics & Sports Medicine, Dr. Jeremy Burnham performs orthopedic independent medical examinations using a systematic, evidence-based methodology that prioritizes thorough record review, standardized physical examination, objective diagnostic findings, and clear written analysis. This page explains the IME process from the examinee’s perspective, including what to expect before, during, and after the evaluation.

What Is an Independent Medical Examination?

An independent medical examination is a focused medical evaluation conducted by a physician who has not previously treated the patient. The term “independent” refers to the fact that the examining physician is not part of the patient’s ongoing treatment team and approaches the case without a pre-existing clinical relationship. The purpose is to provide an objective medical opinion on specific questions posed by the requesting party, which may include an insurance carrier, an employer, an attorney, a judge, or a state workers’ compensation board.

In the workers’ compensation context, IME evaluations typically address one or more of the following questions: Is the diagnosis accurate and complete? Is the current condition causally related to the workplace injury? Is the prescribed treatment reasonable, necessary, and related to the work injury? Has the patient reached maximum medical improvement (MMI)? If so, what is the extent of any permanent impairment? Are there work restrictions, and what functional capacity does the patient retain? These are the questions that shape the IME process, and the examining physician’s written answers directly inform decisions about ongoing benefits, treatment authorization, and claim resolution.

It is important to understand that the IME is not an adversarial event. The role of the examining physician is to provide an honest, well-supported medical opinion based on the available evidence. The findings may support the treating physician’s conclusions, differ from them, or identify additional issues that had not been previously considered. The value of the IME depends entirely on the thoroughness of the evaluation and the clarity of the resulting analysis.

Why an IME Is Requested in Workers’ Compensation Cases

IME evaluations are typically requested when there is a medical question that the existing treatment records do not definitively answer, or when the parties involved in a workers’ compensation claim hold different views about the patient’s medical status. Common scenarios that prompt an IME request include disputes about whether the current condition is related to the workplace injury, disagreements about the appropriateness of proposed surgery or ongoing treatment, questions about when the patient has reached maximum medical improvement, the need for an impairment rating to calculate settlement value, and uncertainty about the patient’s ability to return to work in any capacity.

IME evaluations serve a specific function within the broader workers’ compensation system. While treating physicians focus on diagnosis and treatment, the IME physician is asked to step back and evaluate the case from a broader analytical perspective, considering the full scope of medical records, the mechanism of injury, the clinical findings, the imaging, and the relevant medical literature. This is not a matter of second-guessing the treating physician. It is a mechanism built into the workers’ compensation framework to ensure that medical decisions affecting benefits and treatment authorization are supported by objective evidence.

Who Can Request an IME

In Louisiana, an IME may be requested by several parties. The employer or its workers’ compensation insurance carrier may request an evaluation to obtain an independent opinion on diagnosis, causation, treatment, or work status. An injured worker’s attorney may request an IME (sometimes called a “claimant’s IME” or “second medical opinion”) to address the same questions from an independent standpoint. A workers’ compensation judge or hearing officer may order an IME to assist in resolving a medical dispute. In some cases, the Office of Workers’ Compensation Administration (OWCA) may designate a physician to provide an independent evaluation when the parties cannot agree on medical issues.

Regardless of who requests the evaluation, the examining physician’s obligation is the same: to provide an objective, thorough, and well-documented medical opinion based on the evidence. The requesting party identifies the specific questions to be addressed, but the physician’s conclusions must be based on the medical facts, not on who is paying for the examination.

IME vs. Second Medical Opinion (SMO): Understanding the Difference

The terms “independent medical examination” and “second medical opinion” are often used interchangeably in everyday conversation, but they refer to distinct types of evaluations within most workers’ compensation systems. Understanding the difference matters because the party that requests the examination, the physician who performs it, and the weight given to the resulting opinion can vary significantly between the two.

A second medical opinion (SMO) is typically an examination requested by the employer or its workers’ compensation insurance carrier to obtain an additional medical opinion on diagnosis, causation, treatment, or work status. The physician performing the SMO is selected by the requesting party, often from a list of physicians with experience in workers’ compensation evaluations. The SMO serves as a check on the treating physician’s conclusions, particularly when costly treatment (such as surgery) is proposed or when the case has extended beyond the expected recovery window.

An independent medical examination (IME), in the strictest regulatory sense, refers to an evaluation in which the examining physician is selected by a neutral party, such as a state workers’ compensation commission, a judge, or the director of the state workers’ compensation agency. The IME is intended to resolve disputes between the treating physician’s opinion and the SMO physician’s opinion, or to answer specific medical questions that the existing records do not adequately address. In practice, however, many jurisdictions and practitioners use “IME” as a general term for any physician evaluation conducted by a non-treating physician, regardless of who selected the physician.

From the examinee’s perspective, the process and the examination itself are largely similar between an SMO and an IME. The difference lies in who requested it, who selected the physician, and how the resulting opinion fits into the broader medicolegal framework. Because the terminology varies by state, the sections below describe how Louisiana, Mississippi, Arkansas, Texas, Alabama, and Florida structure non-treating physician evaluations in their respective workers’ compensation systems.

State-by-State Rules: Louisiana, Mississippi, Arkansas, Texas, Alabama, and Florida

Workers’ compensation statutes differ by state, and the rules for who can order an IME or SMO, how the examining physician is selected, and how the resulting opinion is used vary accordingly. Dr. Burnham performs orthopedic evaluations under the applicable statutes of the states in which he is licensed. The following summaries describe the general framework in Louisiana, Mississippi, Arkansas, Texas, Alabama, and Florida, the six Gulf South states most relevant to orthopedic workers’ compensation referrals in this region. The specific application to an individual case depends on the facts, the version of the statute in effect at the time of the injury, and the procedural posture of the claim, so parties should consult counsel licensed in the relevant jurisdiction.

Louisiana. Louisiana’s workers’ compensation system, codified at Title 23 of the Louisiana Revised Statutes, distinguishes clearly between an employer-requested Second Medical Opinion and a state-ordered Independent Medical Examination. Under La. R.S. 23:1121(B), the employer or its insurance carrier is entitled to have the injured employee examined by a physician of the employer’s choosing at reasonable intervals; this examination is commonly referred to as the SMO. Under La. R.S. 23:1123, when a dispute exists between the treating physician and the SMO physician regarding the employee’s condition, the director of the Office of Workers’ Compensation Administration may order an IME, with the examining physician selected by the director rather than by either party. The IME physician’s opinion is afforded significant weight in resolving the medical dispute.

Mississippi. Under Miss. Code Ann. § 71-3-15, the Mississippi Workers’ Compensation Commission may order a medical examination at any time, and the employer or carrier may require the employee to submit to examination at reasonable intervals. In Mississippi, the term “IME” is commonly used for both employer-requested and commission-ordered evaluations, and the statutory framework places the commission in the role of arbiter when medical opinions conflict. The distinction between SMO and IME is therefore less sharply drawn in Mississippi than in Louisiana.

Arkansas. Under Ark. Code § 11-9-511, the employer or its insurance carrier may require the injured employee to submit to medical examination by a physician of the employer’s selection at reasonable times and places. Arkansas does not maintain a formal SMO/IME distinction in statute and refers generally to the examination as a “medical examination”; the Arkansas Workers’ Compensation Commission does not pre-approve or designate the examining physician, though the Commission may adjudicate disputes about the reasonableness of examination demands. The injured employee retains certain procedural protections, including the right to have a representative present during the examination and to request that examination results be shared with the treating physician.

Texas. The Texas Workers’ Compensation Act provides for two distinct types of non-treating physician evaluations. A Required Medical Examination (RME), governed by Texas Labor Code § 408.004, is requested by the insurance carrier and performed by a physician selected by the carrier; it functions analogously to an SMO. A Designated Doctor examination, under § 408.0041, is ordered by the Division of Workers’ Compensation to resolve specific issues such as the date of maximum medical improvement, the impairment rating, the extent of the compensable injury, or the ability to return to work. The Designated Doctor is selected by the Division from a state-approved list, and the opinion is given presumptive weight on the designated issues.

Alabama. Under Ala. Code § 25-5-77, the employer or its workers’ compensation insurance carrier may require the injured employee to submit to examination by a licensed physician of the carrier’s selection at reasonable times and places. Alabama, like Arkansas, does not formally distinguish between SMO and IME designations in statute: the examination is “independent” in the sense that the physician is not the employee’s treating provider, but the physician is selected by the employer/carrier rather than by a neutral third party. The resulting opinion is evaluated as expert evidence under the ordinary credibility standards that apply to medical testimony in Alabama workers’ compensation proceedings.

Florida. Under Fla. Stat. § 440.13(5), each party in a Florida workers’ compensation case is entitled to one IME per accident, with the examining physician selected by the requesting party. When there is a conflict between medical opinions that cannot be resolved by the parties, the judge of compensation claims may appoint an Expert Medical Advisor (EMA) under Fla. Stat. § 440.13(9), and the EMA’s opinion is presumptively correct on the medical issues addressed. Florida’s structure therefore gives each side a party-selected IME, with the EMA mechanism serving the dispute-resolution role that Louisiana assigns to the 1123 IME.

Across all six states, the underlying purpose of the non-treating physician evaluation is the same: to provide an objective, evidence-based medical opinion that helps the parties and the adjudicator resolve specific questions about diagnosis, causation, treatment, and functional status. The procedural route by which the examination is ordered, and the weight given to the resulting opinion, vary by statute. Louisiana, Texas, and Florida maintain formal mechanisms for state- or court-appointed physicians to resolve disputes, while Mississippi, Arkansas, and Alabama rely more heavily on employer-selected physicians with commission or court review of procedural reasonableness.

What Happens Before the Examination

Before the in-person evaluation, the examining physician receives a referral that identifies the patient, describes the relevant workplace injury, and lists the specific medical questions to be addressed. Along with the referral, the physician typically receives the available medical records, which may include emergency department notes, operative reports, office visit notes from the treating physician, physical therapy records, diagnostic imaging reports, and any prior IME reports.

A thorough IME begins with an extensive review of these records before the patient ever enters the examination room. The physician reads the records chronologically, identifies the mechanism of injury, traces the diagnostic workup and treatment timeline, notes any prior injuries or pre-existing conditions affecting the same body part, and develops a preliminary understanding of the medical questions at issue. This advance preparation allows the in-person evaluation to be focused and efficient, and it ensures that the physician can ask informed questions during the patient interview.

For the examinee, the period before the IME is an opportunity to organize relevant information. Keeping a list of current symptoms, medications, treating physicians, and any questions about the process can help ensure that nothing important is overlooked during the evaluation.

The Role of Medical Records Review

The medical records review is arguably the most important component of a high-quality IME, though it occurs largely out of the patient’s view. For orthopedic cases, the records often span months or years and may include documentation from multiple providers. The examining physician reviews these records not merely to confirm what has already been reported but to identify patterns, inconsistencies, gaps in documentation, and clinical findings that inform the causation analysis.

In orthopedic workers’ compensation cases, the records review frequently involves comparing the mechanism of injury described in the initial report with the clinical findings that followed. For example, does the pattern of meniscal tear on MRI match the described mechanism? Were there documented degenerative changes before the work injury that may have contributed to the current condition? Did the imaging findings evolve in a way consistent with acute trauma or chronic degeneration? These questions cannot be answered by physical examination alone. They require careful comparison of the documentary record with the objective clinical and radiographic findings.

Dr. Burnham’s approach to records review draws on published research in diagnostic accuracy, including work on the reliability of MRI interpretation for conditions such as meniscal ramp lesions. In one study, Arner, Burnham et al. evaluated the accuracy of preoperative MRI for detecting posterior meniscocapsular tears in 90 patients, finding sensitivity ranging from 53.9% to 84.6% and specificity from 92.3% to 98.7% (Arner, Burnham et al., 2017). Understanding the diagnostic limitations of imaging modalities is critical when reviewing records and forming causation opinions in workers’ compensation evaluations, because the medical evidence must be interpreted within its known accuracy parameters.

What Happens During the Examination

The in-person IME evaluation typically follows a structured sequence. The examining physician begins with a detailed patient interview, asking about the mechanism of injury, the onset and progression of symptoms, current complaints, functional limitations, prior injuries to the same body region, and relevant medical history. The patient’s own description of the injury and its impact on daily activities is a valuable component of the evaluation and is documented in the report.

Following the interview, the physician performs a focused physical examination specific to the body part or condition at issue. For orthopedic IMEs, this examination is systematic, reproducible, and based on established clinical testing protocols. The physician documents findings using accepted clinical terminology and grading systems, which ensures that the examination results are interpretable by other physicians, attorneys, judges, and administrators who may read the report.

The examination is typically shorter than a comprehensive new-patient office visit because the IME physician is not establishing ongoing care. However, the examination must be thorough enough to support the conclusions in the written report. A well-conducted orthopedic IME includes all of the relevant clinical tests for the body part at issue, assessment of range of motion, palpation, neurovascular examination, and any specialized testing indicated by the referral questions.

The Physical Examination: What Is Tested

For knee-related workers’ compensation IMEs, the physical examination includes inspection for swelling, effusion, and alignment; palpation of the joint line, patella, patellar tendon, and surrounding structures; range-of-motion measurement in flexion and extension; ligament stability testing (Lachman test, anterior drawer, posterior drawer, varus and valgus stress at 0 and 30 degrees, and the pivot-shift test); meniscal provocation tests (McMurray test, joint line tenderness, Thessaly test); and assessment of gait, squat tolerance, and functional movement patterns.

For shoulder evaluations, the examination similarly follows a systematic protocol including rotator cuff testing (Jobe test, external rotation lag sign, lift-off test, bear-hug test), impingement signs (Neer, Hawkins-Kennedy), instability testing (load and shift, apprehension, relocation), and labral provocation tests (O’Brien, compression-rotation). The specific tests performed depend on the body part and the clinical questions being addressed.

Findings are documented as objective and reproducible. For example, rather than recording that the knee is “unstable,” a thorough IME report will document the specific test performed, the grade of laxity, and the endpoint quality (e.g., “Lachman test: 2+ anterior translation with a soft endpoint”). This level of specificity is what makes the physical examination findings useful in the medicolegal context, because they can be compared with findings from other examiners and interpreted by non-medical professionals reading the report.

Diagnostic Imaging in the IME Process

The IME physician reviews all available diagnostic imaging, including plain radiographs, MRI scans, CT scans, and any other studies performed during the course of treatment. In some cases, the physician may recommend additional imaging if the existing studies are inadequate to answer the referral questions. The interpretation of imaging in the IME context goes beyond simple diagnosis. The physician must assess whether the imaging findings are consistent with the described mechanism of injury, whether there is evidence of pre-existing degenerative change, and whether the imaging timeline correlates with the clinical presentation.

For orthopedic cases involving arthritis, the method of radiographic assessment matters. Duncan, Burnham et al. demonstrated the importance of using weight-bearing radiographs rather than supine films when evaluating joint space narrowing, as non-weight-bearing images can significantly underestimate the degree of articular cartilage loss (Duncan, Burnham et al., 2015). In workers’ compensation evaluations, accurately staging the degree of arthritis on imaging directly influences opinions about causation (work-related aggravation vs. pre-existing condition), treatment appropriateness (whether joint replacement is warranted), and impairment rating. Using the correct imaging methodology is therefore essential to producing a defensible medical opinion.

The physician may also review imaging to assess the technical quality of any prior surgical intervention. If a patient has undergone ACL reconstruction or rotator cuff repair, the IME physician can evaluate tunnel placement, graft integrity, or repair tissue quality on postoperative imaging to determine whether the surgical outcome is satisfactory or whether additional intervention may be indicated.

Causation Analysis: Connecting Injury to Work

Causation is often the central question in a workers’ compensation IME. The examining physician must determine, to a reasonable degree of medical certainty, whether the patient’s current condition is causally related to the workplace injury, is an aggravation or acceleration of a pre-existing condition, or is unrelated to the work event. This determination requires integrating the mechanism of injury, the temporal relationship between the event and symptom onset, the clinical and imaging findings, the natural history of the condition, and the relevant medical literature.

Causation analysis in orthopedic cases is rarely straightforward. A worker who injures a knee at work may have pre-existing degenerative meniscal changes that were asymptomatic before the injury. The question is not simply whether the meniscal tear exists (it does) but whether the workplace event caused the tear, made a pre-existing tear symptomatic, or is unrelated to the current symptoms. Answering this question requires understanding the biomechanics of the injury mechanism, the MRI characteristics that distinguish acute traumatic tears from chronic degenerative tears, and the clinical pattern of symptom onset and progression.

Dr. Burnham’s published research on bony morphology and injury risk provides a framework for understanding how anatomic factors influence susceptibility to specific injuries (Burnham et al., 2017). In the IME context, this type of evidence-based analysis helps differentiate between conditions that were caused by a work event and conditions that reflect the natural progression of a pre-existing anatomic predisposition. The goal is always to provide a clear, well-supported opinion that distinguishes what the medical evidence shows from what it does not.

The IME Report: What It Contains

The written IME report is the primary product of the evaluation. A thorough orthopedic IME report typically includes the following components: identification of the examining physician and the requesting party; a list of all medical records reviewed, with dates and sources; a summary of the patient’s history as obtained during the interview; a detailed description of the physical examination findings; a review of the diagnostic imaging; a discussion of the medical issues with reference to the relevant clinical evidence; and the physician’s opinions and conclusions, organized by the specific questions posed in the referral.

The opinions section addresses each referral question directly and provides the reasoning behind each conclusion. For example, if the physician is asked whether the patient has reached maximum medical improvement, the report will explain the basis for that determination, including the current clinical status, the treatment that has been rendered, the expected natural history of the condition, and whether additional treatment is likely to produce meaningful improvement. If the physician disagrees with the treating doctor’s recommendations, the report explains why, citing the clinical findings and the relevant evidence.

Clarity is paramount. The report may be read by attorneys, judges, claims adjusters, and the patient, in addition to other physicians. Conclusions must be stated plainly and supported by the documented findings. When certainty is limited, as it sometimes is, the report should acknowledge that limitation rather than overstate the strength of the available evidence.

What Happens After the IME

After the examination is complete, the physician prepares the written report and sends it to the requesting party. Depending on the case, the report may be shared with the injured worker’s attorney, the employer, the insurance carrier, and the workers’ compensation judge or hearing officer. The report becomes part of the medical evidence in the case and may be used to support decisions about ongoing treatment authorization, maximum medical improvement, impairment ratings, work restrictions, and settlement negotiations.

In some cases, the examining physician may be asked to provide deposition testimony or hearing testimony to explain the findings and conclusions in the report. During testimony, the physician is expected to defend the methodology, explain the basis for the conclusions, and respond to questions from both sides. A well-documented, thorough IME report forms the foundation for effective testimony, because every conclusion can be traced back to specific findings in the record review, physical examination, or imaging.

For the examinee, the period after the IME may involve waiting for the report to be completed and for the parties to respond. The timeline varies, but most IME reports are completed within two to four weeks of the examination. If the report raises new issues or differs significantly from prior medical opinions, it may prompt additional evaluation, treatment changes, or further legal proceedings.

How to Prepare for an IME

Preparation for an IME is straightforward but important. Examinees should arrive on time, bring a valid photo identification, and be prepared to describe the injury, current symptoms, and functional limitations in their own words. Wearing clothing that allows easy access to the body part being examined (shorts for knee evaluations, a loose-fitting top for shoulder evaluations) helps the examination proceed efficiently.

It is helpful to bring a list of current medications, the names and contact information of treating physicians, and any recent imaging or test results that may not yet be included in the records previously sent to the examiner. If there are specific incidents, activities, or symptoms that the examinee believes are important, writing them down in advance ensures that nothing is forgotten during the interview.

Honesty is essential. The examinee should describe symptoms accurately, neither minimizing nor exaggerating limitations. The examining physician is trained to assess consistency between the reported symptoms, the physical examination findings, and the objective medical evidence. An accurate and forthcoming account of the injury and its impact is the best way to ensure that the resulting report fairly represents the examinee’s condition.

How an IME Differs from a Regular Medical Visit

Several features distinguish an IME from a standard physician office visit. First, the IME physician is not establishing a treatment relationship with the patient. The evaluation is conducted for the purpose of providing a medical opinion, not for prescribing treatment. Second, the IME physician has typically reviewed the patient’s entire medical record before the examination, which means the physician arrives with knowledge of the case history that a new treating physician would not have. Third, the examination is documented with greater specificity than a typical office note, because the report may be scrutinized by attorneys, judges, and other physicians. Fourth, the IME physician answers specific questions posed in the referral, rather than developing a treatment plan based on the patient’s chief complaint.

These differences do not mean that the IME is less thorough than a treatment visit. In many cases, the IME is more thorough, because the physician has reviewed the complete medical record and is focused on answering specific clinical questions with a level of precision that the medicolegal context demands. The examining physician’s role is to provide an honest, well-supported opinion that helps the parties involved make informed decisions about the case.

The Bottom Line

An independent medical examination in a workers’ compensation case is a structured, objective medical evaluation designed to answer specific questions about diagnosis, causation, treatment, and functional status. Understanding the process removes much of the uncertainty that examinees experience. Through Burnham Orthopedics & Sports Medicine, Dr. Burnham conducts orthopedic IMEs with a methodology that emphasizes comprehensive records review, systematic physical examination, evidence-based imaging interpretation, and clear written analysis.
