Patient presents with classic symptoms of insulin-dependent diabetes mellitus, also known as type 1 diabetes, including polyuria, polydipsia, polyphagia, and unexplained weight loss.  The patient reports increased frequency of urination, excessive thirst, and constant hunger despite increased food intake.  Recent weight loss of [amount] pounds has been noted over the past [duration].  Presenting blood glucose level is [value] mgdL.  Family history is positive for autoimmune disorders, though not specifically type 1 diabetes.  Based on the patient's symptoms, elevated blood glucose, and family history suggesting autoimmune predisposition, a diagnosis of insulin-dependent diabetes mellitus (type 1 diabetes) is made.  The patient's HbA1c is [value], further supporting the diagnosis. Differential diagnoses considered include type 2 diabetes and maturity-onset diabetes of the young (MODY). However, the patient's presentation, age, and rapid onset of symptoms point towards type 1 diabetes.  Treatment plan includes initiation of insulin therapy with a basal-bolus regimen, diabetes self-management education and training (DSMT),  regular blood glucose monitoring,  nutritional counseling for diabetic meal planning, and close follow-up to monitor glycemic control and assess for potential complications such as diabetic ketoacidosis (DKA), retinopathy, neuropathy, and nephropathy. Patient education materials on insulin administration, carbohydrate counting, and hypoglycemia management were provided.  Follow-up appointment scheduled in two weeks to review insulin titration, self-monitoring blood glucose logs, and address any concerns.  ICD-10 code E10.9 and relevant CPT codes for diabetes management, education, and evaluation will be documented for medical billing and coding purposes.
