A 14-year-old patient with an abscessed tooth presented to the physician’s office with possible sepsis. The tooth had gone untreated for two weeks, and now the patient is experiencing a high fever, severe headaches and toothaches and malaise and fatigue. The physician suspects that the bacteria from the tooth has spread to the patient’s blood and is now a systemic infection. As part of the office procedure, the physician orders a CBC in order to examine the bacterial levels in the patient’s blood. After the physician writes the orders, the nurse performs a venipuncture on the patient in order to obtain a blood sample. What is the correct code for the collection of the blood only?
