What term describes an entity, such as Medicare or Medicaid, that pays for part or all of a resident's charges?

The term that describes an entity, such as Medicare or Medicaid, which pays for part or all of a resident's charges is a third party payer. This designation is used because these entities are not the provider of services or the end consumer; instead, they act as intermediaries that cover the costs associated with healthcare services.

Third party payers often negotiate rates with service providers and are responsible for processing claims and disbursing payments based on the coverage policies in place. In the case of Medicare and Medicaid, they fulfill vital roles in helping individuals access necessary medical care without bearing the entire financial burden.

The other choices do not accurately reflect this role. An insurance broker is typically an intermediary that helps consumers find and purchase insurance plans but does not pay for services themselves. A claim adjuster assesses insurance claims to determine the extent of the insurer's liability but does not represent a payor. An underwriter evaluates the risk of insuring an individual or entity and decides on coverage terms, but they also are not directly involved in payment for services.
