Answer: A
Z03.6 is the correct code as it is used for “encounter for observation for suspected toxic effect from ingested substance ruled out.” Here, the mother is suspected of the consumption of the sedatives by the child. Later on, the suspicion was ruled out.
Option B is not correct because Z03.821 is used for “Encounter for observation for suspected ingested foreign bodies ruled out.”
Option C is not correct because Z03.822 codes “encounter for observation for suspected aspirated (inhaled) foreign body ruled out.”
Option D is not correct because Z03.823 codes “encounter for observation for suspected inserted (injected) foreign bodies ruled out.”
