K22.8Other specified diseases of esophagus

K22.8 is the ICD-10-CM diagnosis code for other specified diseases of 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 3 subcodes must be used instead.

Within K22, choose K22.8 (Other specified diseases of esophagus) only when documentation doesn't support a more specific option: 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), Barrett's esophagus (K22.7) and 1 more.

To report this condition, pick the subcode that matches the documentation: K22.81 (polyp), K22.82 (polyp) and K22.89 (esophagus).

The conditions in its Excludes2 note aren't part of K22.8, but may be coded alongside it if the patient has both: esophageal varices (I85.-) and Paterson-Kelly syndrome (D50.1).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2022 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 530.82 (esophageal hemorrhage), 530.83 (esophageal leukoplakia) and 530.89 (other specified disorders of esophagus).
