Problem:
Using the CPT and ICD-10-CM manuals, identify the codes for the following cases: An established patient is admitted on observation status for influenza symptoms and extreme nausea and vomiting. The patient is dehydrated and has been experiencing dizziness and mental confusion for the past 2 days. Prior to this episode the patient was well but became acutely ill overnight with these symptoms. Given the abrupt onset of these symptoms, the physician has to consider multiple possible causes and orders a variety of laboratory tests to be performed. The patient is at risk for a moderate number of complications. The MDM complexity is moderate. A comprehensive history is collected, and a comprehensive head to-toe physical examination is performed. Hint: there is 1 CPT code and 4 ICD-10-CM codes for this patient. First code: Blank 1 Second code: Blank 2 Other code 1: Blank 3 Other code 2: Blank 4 Other code 3: Blank 5
