Patient presents with signs and symptoms suggestive of Graves' disease, a form of hyperthyroidism.  Key findings include palpitations, heat intolerance, weight loss despite increased appetite, anxiety, tremor, and ophthalmopathy characterized by exophthalmos and lid lag.  On physical examination, a diffusely enlarged thyroid gland with a bruit was noted.  Pretibial myxedema was absent.  Laboratory evaluation reveals elevated free T4 and free T3 levels with suppressed TSH.  Thyroid stimulating immunoglobulin (TSI) and thyroid peroxidase antibodies (TPOAb) were ordered to confirm the diagnosis of Graves' hyperthyroidism.  Differential diagnosis includes other causes of hyperthyroidism such as toxic multinodular goiter and thyroiditis.  The patient's presentation, thyroid function tests, and antibody results are consistent with the diagnostic criteria for Graves' disease.  Treatment options including antithyroid medications (methimazole or propylthiouracil), radioactive iodine therapy, and thyroidectomy were discussed with the patient.  Risks and benefits of each treatment modality were explained.  The patient will be started on methimazole with close monitoring of thyroid function and potential side effects such as agranulocytosis.  Patient education regarding medication adherence, symptom management, and the importance of regular follow-up appointments was provided.  ICD-10 code E05.0 and CPT codes for evaluation and management (e.g., 99203, 99214) will be used for billing and coding purposes depending on the complexity of the visit.  Follow-up appointment scheduled in 4 weeks to assess treatment response and adjust medication dosage as needed.
