CodingQuestion 25 of 100

The 'Z codes' in ICD-10-CM are primarily used to report:

a.Only fatal conditions
b.External causes of morbidity
c.Poisonings and toxic effects
d.Factors influencing health status and contact with health services, such as screenings or aftercare

Explanation

Z codes describe reasons for encounters other than a current illness or injury, such as routine examinations, immunizations, screenings, aftercare, and personal or family history. Some Z codes may be first-listed while others are only secondary. They help explain the medical necessity of preventive and follow-up visits.
