Which of the following reimburses its insureds for covered medical expenses?

The correct answer is commercial insurers, as these organizations are designed to provide reimbursement for covered medical expenses incurred by their insured clients. Commercial insurers operate on a business model where they collect premiums from policyholders and in return, they agree to pay for certain medical costs as specified in the policy, such as hospital stays, treatments, and procedures.

While self-insurers may cover their own medical expenses, they do not typically reimburse in the same way as commercial insurers because they assume the financial risk themselves rather than transferring it to an insurance company. Health maintenance organizations (HMOs) provide a network of healthcare services for their members, usually requiring them to use a specific network of providers, but they may not operate primarily on a reimbursement model. Social health programs often focus on specific populations and may not follow the traditional reimbursement structure found in commercial insurance.

Commercial insurers play a critical role in the healthcare system by providing services that help individuals manage unpredictable medical expenses, ensuring that policyholders receive appropriate care without bearing the full financial burden upfront.
