Case finding methods for patients with diabetes include all of the following except which?

• A. Review of problem list
• B. CPT diagnostic codes
• C. Laboratory test results
• D. Medication history

Answer: (B)

Case finding relies on data that reveal who has diabetes based on documentation, measurements, and ongoing treatment. A problem list is a direct source of diagnosed conditions; if diabetes appears there, it flags the patient as having the condition. Laboratory test results provide objective evidence of glycemic status, such as elevated glucose readings or HbA1c levels, which help identify both existing diabetes and risk. Medication history shows what treatments a patient is currently receiving—antidiabetic drugs or insulin use strongly indicate diabetes management. CPT codes, by contrast, are billing or service-reported codes used to document procedures and services for claims. They don’t reliably indicate a patient’s diabetes status on their own and aren’t used as the primary method to find individuals with diabetes. They may appear after a diagnosis is already established, but they aren’t the source that identifies cases.
