Patient presents with complaints suggestive of vitamin C deficiency (ascorbic acid deficiency, scurvy).  Symptoms include fatigue, malaise, and myalgia.  The patient also reports gingival bleeding and petechiae on the lower extremities.  Dietary history reveals limited fruit and vegetable intake.  Physical examination reveals swollen, bleeding gums and perifollicular hemorrhages.  Diagnosis of vitamin C deficiency is based on clinical presentation, dietary history, and physical findings.  Laboratory testing, including plasma vitamin C levels, may be considered for confirmation.  Differential diagnosis includes other bleeding disorders, malnutrition syndromes, and connective tissue diseases.  Treatment plan includes oral ascorbic acid supplementation, dietary counseling emphasizing vitamin C-rich foods (citrus fruits, berries, leafy greens), and monitoring for symptom resolution.  Patient education provided regarding the importance of adequate vitamin C intake for collagen synthesis, immune function, and antioxidant protection.  Follow-up appointment scheduled to assess treatment response and monitor for potential complications such as anemia and impaired wound healing.  ICD-10 code E54, vitamin C deficiency, assigned.  CPT codes for evaluation and management services, as well as laboratory testing if performed, will be documented accordingly.
