How to code Abdominal Distension and Bloating

R14.0 is abdominal distension (gaseous), which also covers bloating and tympanites. Gas pain is R14.1, eructation (belching) is R14.2, and flatulence is R14.3.

Swelling or a mass inside the abdomen that is not from gas is coded from R19.0-, such as R19.00 for an unspecified site. Distension from fluid is ascites (R18.-). Drop the symptom code when a diagnosis that explains it is made, such as constipation K59.00.
