Medical Coding

Answer: B - The Rule of Nines calculates the extent of burn on the human body. In order to classify the extent of a burn on the human body, the body is theoretically divided up into sections with each composing 9% of the body. The Rule of Nines is adjusted according to the age of the patient and the percentages change when describing the extent of burns for children and adolescents. The Rule of Nines is commonly used in integumentary section codes when describing the extents of burns. The coder must be able to assign the correct code, by taking into account the extent of burn on the patient’s body.
