About K20.8

K20.8 is the ICD-10-CM diagnosis code for other esophagitis. It belongs to category K20 (esophagitis), 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 K20, choose K20.8 (Other esophagitis) only when documentation doesn't support a more specific option: eosinophilic esophagitis (K20.0) and unspecified (K20.9).

To report this condition, pick the subcode that matches the documentation: K20.80 (without bleeding) and K20.81 (with bleeding).

Use an additional code to identify: alcohol abuse and dependence (F10.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2021 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 530.19 (other esophagitis).
