Patient presents with nausea and vomiting.  Onset, duration, frequency, and volume of emesis were documented.  Associated symptoms such as abdominal pain, fever, diarrhea, headache, dizziness, or lightheadedness were explored and recorded.  Character of emesis (e.g., bilious, bloody, coffee-ground appearance) was noted.  Recent dietary intake, travel history, medication use (including over-the-counter medications and supplements), and potential exposures to infectious agents were reviewed.  Physical examination findings including vital signs, hydration status (e.g., mucous membranes, skin turgor), abdominal tenderness, and bowel sounds were documented.  Differential diagnosis considerations include gastroenteritis, food poisoning, medication side effects, pregnancy, dehydration, migraine, appendicitis, intestinal obstruction, cholecystitis, pancreatitis, and cyclic vomiting syndrome.  Severity of nausea and vomiting was assessed based on frequency and presence of dehydration signs.  Treatment plan may include antiemetics (e.g., ondansetron, promethazine), intravenous fluids for rehydration if indicated, and dietary modifications (e.g., clear liquids).  Patient education provided regarding self-care measures for nausea and vomiting management, including oral rehydration therapy and dietary recommendations.  Follow-up instructions and return precautions were discussed.  ICD-10 code considerations include R11.0 for nausea with vomiting, unspecified; R11.1 for nausea alone; R11.2 for vomiting alone; and additional codes for underlying causes if identified.  CPT code considerations may include evaluation and management codes based on the complexity of the visit.
