Final answer:
Code 01 'spouse' corresponds to the choice A) Patient's relationship to the insured on healthcare forms, indicating the patient is the spouse of the insured person.
Step-by-step explanation:
Code 01, labeled as 'spouse,' refers to the patient's relationship to the insured. In the context of form locators on healthcare forms, this would be choice A) Patient's relationship to the insured. This code is used to specify the particular connection or association that the patient has with the policyholder or subscriber of a health insurance plan. For instance, if the patient is the spouse of the individual who holds the insurance policy, code 01 would be the appropriate selection on the form. Different codes exist to represent different relationships such as child, parent, or other dependents.
