Patient presents with glycosuria, defined as glucose in urine, confirmed by urinalysis showing positive glucose and elevated urine glucose concentration.  Differential diagnosis includes diabetes mellitus type 1, diabetes mellitus type 2, gestational diabetes, renal glycosuria, and other causes of hyperglycemia.  Patient's fasting blood glucose, HbA1c, and complete metabolic panel were ordered to evaluate for underlying diabetes and assess renal function.  Patient history was reviewed for risk factors such as family history of diabetes, obesity, polyuria, polydipsia, polyphagia, and recent infections.  Physical exam revealed  (insert relevant findings, e.g., normal weight, no signs of dehydration).  Based on the initial assessment, the preliminary diagnosis is (insert suspected cause of glycosuria, e.g., renal glycosuria vs. diabetes mellitus).  Further investigations, including glucose tolerance test and assessment of renal glucose threshold, may be indicated depending on initial laboratory results.  Patient education provided regarding glucose monitoring, dietary modifications, and potential need for medication management.  Follow-up appointment scheduled to review laboratory findings and discuss management plan based on confirmed etiology of glycosuria.  ICD-10 code R81 (abnormal findings on examination of urine) and CPT code 81003 (urinalysis, automated, without microscopy) are provisionally considered pending final diagnosis.  Medical billing will be adjusted based on the definitive diagnosis and treatment plan.
