An independent medical exam can directly affect wage-loss benefits, medical treatment approval, and the overall value of a claim. If the examiner says an injury is less serious, not work-related, or already healed, an employer or insurer may use that opinion to limit temporary disability payments, deny care, or dispute permanent impairment.

Technically, an independent medical exam, often called an IME, is an evaluation performed by a doctor who is asked to examine an injured person and give an opinion about diagnosis, cause of injury, work restrictions, need for treatment, and degree of impairment. The doctor is usually not the worker's treating physician. Despite the word "independent," the exam is commonly requested by an employer, insurer, or opposing party to answer disputed medical questions. The examiner typically reviews records, takes a history, performs a physical exam, and issues a written report.

In practice, the IME can become a turning point in a workers' compensation case, especially when there is disagreement over whether an injury came from the job, whether the worker can return to duty, or whether ongoing symptoms are tied to the original incident. On Oahu construction work zones and other physically demanding jobs, those disputes often arise after back, neck, or shoulder injuries.

In Hawaii workers' compensation cases, medical examinations may be required under Hawaii Revised Statutes § 386-79. Refusing a properly requested exam can create problems for benefits, while an unfavorable IME may need to be challenged with records from a treating doctor, a second opinion, or other medical evidence before the Disability Compensation Division.
