Code Description

ICD-10 Z01.021 is a billable code used to indicate a diagnosis of encounter for examination of eyes and vision following failed vision screening with abnormal findings.

Key Diagnostic Point:

Z01.021 is utilized when a patient presents for a comprehensive eye examination after failing a vision screening that revealed abnormal findings. This encounter is crucial for identifying potential vision issues that may not have been apparent during the initial screening. Factors influencing health status, such as socioeconomic status, access to healthcare, and education, play a significant role in the likelihood of patients undergoing vision screenings. Preventive care through regular eye examinations can help detect conditions like refractive errors, amblyopia, or other ocular diseases early, improving outcomes. The use of this code emphasizes the importance of follow-up care after abnormal screening results, ensuring that patients receive appropriate interventions. Social determinants, such as lack of transportation or financial barriers, may affect a patient's ability to seek follow-up care, highlighting the need for healthcare providers to address these issues during patient interactions.
