Final answer:
A (B) Z code is used in outpatient settings to indicate a patient is healthy with no diseases or injuries for encounters like screenings or immunizations.
Step-by-step explanation:
When a patient is healthy and has no problems, a Z code is used in the outpatient setting. These codes are part of the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) and are used for encounters for circumstances other than a disease or injury.
The Z codes represent factors that influence health status and contact with health services that include a wide range of situations, such as immunization, screening, and healthy individuals accompanying a sick person.
