Clinical & Coding Specifications
Clinical Context
A 52-year-old patient with obesity and a family history of type 2 diabetes presents to their primary care clinic for an annual preventive visit. The clinician orders a diabetes screening test due to risk factors including BMI >30 and a history of hypertension. The patient has fasting and nonfasting options; the clinic performs a point-of-care hemoglobin A1c or arranges a laboratory fasting plasma glucose or oral glucose tolerance test per practice protocol. Specimen collection, processing, and reporting occur during the visit or via the outpatient laboratory. Billing for the screening event uses the HCPCS Level II code G8777 to indicate a diabetes screening test was performed. Results are reviewed with the patient, and appropriate follow-up is documented in the medical record.
