Answer: When a patient is asymptomatic, an ED coder must usually rely on the V codes. For instance, the diagnosis code on a claim for a patient examined after being exposed to blood would be V15.85 (other specified personal history presenting hazards to health; exposure to potentially hazardous body fluids). If the patient also exhibits symptoms, however, those would be reported in the primary position on the claim form. Perhaps a passenger in a car involved in an accident sustained a laceration to the hand and was exposed to another individual's blood. An ED visit would be reported, along with a diagnosis code describing the hand wound (e.g., 882.0, open wound of hand except finger[s] alone; without mention of complication) in the primary position and V15.85 in the secondary position. An E code to explain the circumstances of the accident would also be assigned. |
