About Chapter 11
Chapter 11 (K00–K95) covers a wide range of diseases and disorders affecting the digestive system. These codes are used to identify conditions that impact organs involved in digestion, such as the mouth, esophagus, stomach, intestines, liver, pancreas, and gallbladder.
This chapter includes codes for digestive system diseases ranging from common issues like acid reflux and gastritis to more complex conditions such as inflammatory bowel diseases, liver cirrhosis, and intestinal obstructions. It also covers disorders of the teeth and gums, as well as complications related to digestion and absorption of nutrients. Medical coders and healthcare providers use these codes to document clinical diagnoses and assist in treatment planning for gastrointestinal health, ensuring accurate representation of digestive system conditions in medical records and claims. These codes help track digestive diseases by specifying both the location and nature of the disorder.
