Clinical Information for Esophagitis (K20)

Eosinophilic Esophagitis - Chronic ESOPHAGITIS characterized by esophageal mucosal EOSINOPHILIA. It is diagnosed when an increase in EOSINOPHILS are present over the entire esophagus. The reflux symptoms fail to respond to PROTON PUMP INHIBITORS treatment, unlike in GASTROESOPHAGEAL REFLUX DISEASE. The symptoms are associated with IgE-mediated hypersensitivity to food or inhalant allergens.

Esophagitis - INFLAMMATION, acute or chronic, of the ESOPHAGUS caused by BACTERIA, chemicals, or TRAUMA.

Esophagitis, Peptic - INFLAMMATION of the ESOPHAGUS that is caused by the reflux of GASTRIC JUICE with contents of the STOMACH and DUODENUM.

Type 1 Excludes Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

erosion of esophagus K22.1
esophagitis with gastro-esophageal reflux disease K21.0
reflux esophagitis K21.0
ulcerative esophagitis K22.1

Type 2 Excludes Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
