Individuals and businesses purchase insurance policies to protect against monetary losses. In the event of a loss, policyholders submit claims, or requests for payment, seeking compensation for their loss. Adjusters, appraisers, examiners, and investigators work primarily for property and casualty insurance companies, for whom they handle a wide variety of claims alleging property damage, liability, or bodily injury. Their main role is to investigate the claims, negotiate settlements, and authorize payments to claimants, all the while mindful not to violate the claimant’s rights under Federal and State privacy laws. They must determine whether the customer’s insurance policy covers the loss and how much of the loss should be paid to the claimant. Although many adjusters, appraisers, examiners, and investigators have overlapping functions and may even perform the same job, the insurance industry generally assigns specific roles to each of these claims workers.

Acute pain, such as occurs with trauma, often has a reversible cause and may require only transient measures and correction of the underlying problem. In contrast, chronic pain often results from conditions that are difficult to diagnose and treat, and that may take a long time to reverse. Some examples include cancer, neuropathy, and referred pain. In such situations, the pain itself is frequently managed separately from the underlying condition of which it is a symptom.
