Which of the following is NOT a type of insurance?

The correct choice, which denotes the option that is not a type of insurance, is identified as contracted services insurance. While indemnity insurance, managed care plans, and life insurance represent established categories of insurance that provide specific types of coverage, contracted services insurance does not correspond with recognized or standard insurance classifications.

Indemnity insurance offers a reimbursement model for medical expenses incurred, allowing policyholders the freedom to choose their healthcare providers. Managed care plans, on the other hand, involve a network of healthcare providers and facilities to offer services while maintaining cost efficiency. Life insurance provides financial protection to beneficiaries upon the policyholder's death, ensuring that loved ones have some financial security.

In contrast, contracted services insurance is not a widely recognized category within the insurance field. It may refer to arrangements for specific services but lacks the defined structure or regulatory recognition as insurance products, making it the correct answer to identify what is not a type of insurance.
