Encounter for screening for diabetes mellitus

This code signifies a patient encounter primarily for the purpose of screening for diabetes mellitus. It is used when a patient presents without symptoms or a known diagnosis of diabetes, and the healthcare provider is performing tests to identify the potential presence of the condition. This includes routine screenings as part of preventative care.

Apply this code when a patient undergoes a glucose tolerance test, fasting blood glucose, or HbA1c specifically for screening purposes. It is appropriate for patients with risk factors for diabetes but no current diagnosis, or as part of a general health check-up where diabetes screening is performed. Do not use if the patient is already diagnosed with diabetes or is presenting with symptoms suggestive of diabetes.

• Always sequence this code as the primary diagnosis when screening is the sole reason for the encounter.
• Do not use this code if the patient has a confirmed diagnosis of diabetes; instead, code the specific type of diabetes.
• If abnormal findings are discovered during the screening, code the abnormal finding(s) in addition to this screening code.
