Get Codes

Diseases of the digestive system is a chapter in ICD-11 that includes conditions affecting the organs involved in digestion, absorption, and elimination, such as the esophagus, stomach, intestines, liver, gallbladder, pancreas, and associated structures. These disorders may arise from infections, inflammation, functional disturbances, structural abnormalities, or metabolic and autoimmune processes, leading to symptoms like abdominal pain, nausea, vomiting, diarrhea, constipation, or impaired nutrient absorption.

This chapter covers a wide range of gastrointestinal conditions, including disorders of the upper and lower digestive tract, hepatobiliary and pancreatic diseases, and functional gastrointestinal disorders. Accurate classification supports effective diagnosis, treatment planning, and long-term management, while also contributing to clinical research, disease surveillance, and public health strategies aimed at promoting digestive health and preventing complications.
