Which of the following is NOT an example of a code category?

• A. Mechanical codes
• B. Electrical codes
• C. Medical codes
• D. Fire codes

Answer: (C)

The concept being tested is which types of codes belong to safety and construction regulation versus codes used in healthcare billing and classification. In building and fire safety, you deal with categories like mechanical codes, electrical codes, and fire codes. Mechanical codes govern systems that heat, ventilate, and move air; electrical codes cover wiring, circuits, and electrical safety; fire codes address fire prevention, means of egress, suppression systems, and general life-safety requirements. Medical codes, however, are used in healthcare to classify diseases, procedures, and billing (like ICD or CPT). They aren’t part of building or fire safety code categories. So medical codes are not an example of a code category in this context, while the others are.
