CAC suggests a pneumonia code after reading “rule out pneumonia” in an ED note that was later clarified as negative. What CAC limitation does this illustrate?

Short Explanation
“Rule out pneumonia” is the classic CAC trap—software hears “pneumonia” and misses the “rule out.” That’s why a person still has to read the sentence like a coder, not like a keyword scanner.
Full Explanation
NLP-based CAC may fail to interpret negation, uncertainty, or ruled-out conditions and can propose unsupported diagnoses. Coders must review suggestions in clinical context. Relying on CAC without validating negation-sensitive language increases overcoding risk.
