Which procedure would NOT be coded using a code from the respiratory system codes?

• A. nasal polypectomy
• B. frontal sinus CT scan
• C. nasal fracture repair
• D. excision of skin of nose

Answer: (D)

Procedures that use respiratory system codes are those that involve the airway structures themselves, like the nasal cavity and paranasal sinuses. Removing tissue from the nasal cavity (nasal polypectomy) and repairing the nasal bones (nasal fracture repair) clearly affect airway-related anatomy, so they would be coded under the respiratory system. A frontal sinus CT scan is an imaging study of the sinus area. Imaging procedures are typically coded in Radiology rather than under a respiratory-system procedure code, so it isn’t coded as a respiratory procedure. The nose’s skin, however, is part of the integumentary system, not the airway. Excision of skin of the nose is an integumentary procedure, not a respiratory one. So, the procedure that would not be coded using a respiratory system code is the removal of skin from the nose.
