When performing diagnostic endoscopy and/or colonoscopy and the diagnosis codes used are signs and symptoms. However, the endoscopy or colonoscopy is normal. The diagnosis codes used default to the signs and symptoms based on ICD-10 guidelines - coding signs and symptoms if no definitive diagnosis at end of encounter. There is a discussion about the use of K31.89 (other diseases stomach/duodenum) or K59.9 (functional intestinal disorder). I have not seen any coding guidance on the usage of K31.89 or K59.9 Any assistance would be appreciated.
