Document:
A Symptom due to a diagnosis v. another diagnosis codes to the Symptom. However, a Diagnosis v. another diagnosis causing a Symptom codes to either Diagnosis.
Symptom codes show low Severity of Illness (SOI). For example, abdominal pain due to pancreatitis v. cholecystitis codes to abdominal pain. Consider instead “possible acute pancreatitis v. possible acute cholecystitis causing abdominal pain.” This would code to either pancreatitis or cholecystitis.
Dyspnea due to COPD v. Pneumonia codes to dyspnea. Consider instead “possible acute ex of COPD v. possible Pneumonia causing dyspnea." This would code to either acute ex of COPD or Pneumonia.
