Final answer:
If the physicians OIS grading differs from the AIS definition of the injury, the coding should be based on the AIS definition of the injury. The AIS is a standardized system used to classify and code injuries based on their severity and anatomical location.
Step-by-step explanation:
If the physicians' OIS grading differs from the AIS definition of the injury, the coding should be based on the AIS definition of the injury. The AIS (Abbreviated Injury Scale) is a standardized system used to classify and code injuries based on their severity and anatomical location. It is widely accepted and used by medical professionals for coding purposes.
When there is a discrepancy between the physician's OIS grading and the AIS definition, it is important to follow the AIS guidelines to ensure consistency and accuracy in coding. By using the AIS definition, it ensures that the coding reflects the standardized severity and anatomical classification of the injury.
For example, let's say a physician grades an injury as moderate based on their observation, but the AIS definition classifies it as severe. In this case, the AIS definition should be used for coding, as it provides a standardized and objective assessment of the injury.
