Patient presents with symptoms suggestive of hereditary hemochromatosis, including fatigue, joint pain, abdominal pain, and skin hyperpigmentation.  The patient reports a family history of iron overload, raising suspicion for HFE-related hereditary hemochromatosis.  Physical examination reveals hepatomegaly.  Laboratory findings show elevated serum iron, transferrin saturation, and ferritin levels.  Genetic testing for HFE gene mutations (C282Y and H63D) is ordered to confirm the diagnosis of hereditary hemochromatosis or rule out other causes of iron overload, such as secondary hemochromatosis.  Initial diagnostic evaluation includes liver function tests (LFTs) to assess for liver damage and potential complications like cirrhosis or hepatocellular carcinoma.  Based on the patient's transferrin saturation and ferritin levels, therapeutic phlebotomy is recommended as the primary treatment to reduce excess iron stores.  Patient education regarding dietary iron restriction and avoidance of iron supplements is provided.  Follow-up appointments are scheduled to monitor iron levels, liver function, and overall response to treatment, focusing on iron chelation therapy if phlebotomy is contraindicated.  Medical coding will utilize ICD-10-CM code E83.11 for hereditary hemochromatosis and relevant CPT codes for phlebotomy (e.g., 36430) and laboratory tests.  This diagnosis and treatment plan are consistent with current clinical practice guidelines for the management of hemochromatosis.
