About K22.7

K22.7 is the ICD-10-CM diagnosis code for Barrett's esophagus. It belongs to category K22 (other diseases of esophagus), 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 2 subcodes must be used instead.

Within K22 (other diseases of esophagus), K22.7 is specifically for Barrett's esophagus. Related codes cover Achalasia of cardia (K22.0), ulcer of esophagus (K22.1), esophageal obstruction (K22.2), perforation of esophagus (K22.3), dyskinesia of esophagus (K22.4), diverticulum of esophagus, acquired (K22.5), Gastro-esophageal laceration-hemorrhage syndrome (K22.6), other specified diseases of esophagus (K22.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: K22.70 (without dysplasia) and K22.71 (with dysplasia).

Don't report K22.7 together with the conditions in its Excludes1 note: Barrett's ulcer (K22.1) and malignant neoplasm of esophagus (C15.-).

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