A medical impairment rating exam, also known as a disability rating evaluation, is a medical evaluation used to assess the degree of impairment or disability a person may have as a result of a work-related medical condition or injury. The purpose of the exam is to determine the level of functional limitations that the person may have and to assign a rating that reflects the extent of their disability. The rating is then used to determine eligibility for disability benefits or compensation.

During the exam, the physician or other medical professional will typically review the patient's medical records and history, perform a physical examination, and administer various tests to assess the person's abilities and limitations. They will typically evaluate the patient's range of motion, strength, coordination, and any other factors that may impact their ability to perform certain tasks or activities.

The physician may also use various assessment tools or questionnaires to help determine the extent of the person's impairment or disability. These may include standardized rating scales that are widely recognized and used to evaluate specific conditions or injuries.

After the evaluation is complete, the physician will typically provide a report that includes a summary of their findings, an assessment of the patient's level of impairment or disability, and a rating based on established guidelines or standards. This rating may be expressed as a percentage of impairment or disability, which is used to determine eligibility for benefits or compensation.
