Repair L lower arm subcutaneous tissue and fascia, OPEN approach Q: A patient is found down in an apartment fire without cardiac activity and was resuscitated and transported. She had a bronchoscopy and found to have a mild inhalation injury with elevated carbon monoxide levels. How would you code this injury and why? - Correct Answer A: This would be coded as an inhalation injury. The asphyxia codes do not apply to inhalation injury. Carbon monoxide poisoning is not a codeable injury and asphyxia applies to mechanical constriction or restriction of the airway. You may only code the inhalation injury. Q: When you start coding with ICD-10, there are many questions that arise. You need to make a decision on how specific you want to be with your code selection? There are many thoughts on coding in trauma systems and you may ask should you code everything as specific as possible? Or, can you code less specifically and perhaps have a more efficient work process for your registrars? - Do very specific codes have an impact on our ISS? In other words, if I code super specific, will my ISS's be higher? - Correct Answer A: In regard to theses question, we recommend coding as specifically as possible using the AIS Dictionary, and not relying on the computer to identify the codes since they don't always match and may give you inaccurate AIS conversions and therefore inaccurate ISS.
