Reader Question:

List Most Specific Diagnosis

Question: A primary care physician referred a patient suffering from symptoms such as a cough, heartburn, and acid stomach for our surgeon to perform an EGD to rule-out GERD. What diagnosis should we report?

Answer: That depends on the findings. For instance, if the surgeon notes esophagitis during the esophagogastroduodenoscopy (EGD) procedure and the clinician affirms a diagnosis of gastro-esophageal reflux disease (GERD) based on clinical and surgical findings, you can report K21.0 (Gastro-esophageal reflux disease with esophagitis).

Remember: You should always wait for the path report or other definitive diagnosis after the procedure to properly code the diagnosis. If the procedure doesn't result in a definitive diagnosis, then you should code the signs and symptoms that were the reason for the procedure.

In this case, the signs and symptoms that led to the request for an EGD procedure were among the following:

  • R12 (Heartburn)
  • R05 (Cough)
  • K30 (Functional dyspepsia).

Other symptoms that might trigger an EGD order include these symptoms:

  • R06.2 (Wheezing)
  • J37.0 (Chronic laryngitis)
  • J37.1 (Chronic laryngotracheitis).

Important: These symptoms can sometimes also be caused by cardiac or pulmonary problems, so make it a point to report any pre-existing chronic conditions and habits that may exacerbate GERD such as asthma (J45.-), obesity (E66.-), smoking, pregnancy and hereditary predisposition.
