About K22

K22 is the ICD-10-CM diagnosis code for other diseases of esophagus. It belongs to block K20-K31 (diseases of esophagus, stomach and duodenum) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: K22.0 (cardia), K22.1 (esophagus), K22.2 (obstruction), K22.3 (esophagus), K22.4 (esophagus), K22.5 (acquired), K22.6 (syndrome), K22.7 (esophagus) and 2 more.

The conditions in its Excludes2 note aren't part of K22, but may be coded alongside it if the patient has both: esophageal varices (I85.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
