Other diseases of esophagus (K22) ICD-10-CM
The K22 code range covers other diseases of esophagus with 21 ICD-10-CM diagnosis codes. 16 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the K22 range.
Barrett Esophagus
A condition with damage to the lining of the lower ESOPHAGUS resulting from chronic acid reflux (ESOPHAGITIS, REFLUX). Through the process of metaplasia, the squamous cells are replaced by a columnar epithelium with cells resembling those of the INTESTINE or the salmon-pink mucosa of the STOMACH. Barrett's columnar epithelium is a marker for severe reflux and precursor to ADENOCARCINOMA of the esophagus.
Esophageal Achalasia
A motility disorder of the ESOPHAGUS in which the LOWER ESOPHAGEAL SPHINCTER (near the CARDIA) fails to relax resulting in functional obstruction of the esophagus, and DYSPHAGIA. Achalasia is characterized by a grossly contorted and dilated esophagus (megaesophagus).
Esophageal Perforation
The presence of a hole or other type of opening in the esophageal wall through which the contents of the esophagus can pass into the mediastinum. The most common cause of esophageal perforation is injury during a medical procedure such as esophagoscopy or placement of a naso-gastric tube; and pathologic process such as neoplasm or gastric reflux with ulceration. Less common causes include injuries from penetrating or blunt trauma or injury to the esophagus during an operation on another organ, mechanical problem such as violent retching or vomiting; ingestion of a foreign body or caustic agents. The condition often results in infection of the mediastinum and mediastinitis.
Esophageal Polyp
A rare benign intraluminal polypoid tumor that arises from the mucosal surface of the esophagus. This category includes squamous papilloma and giant fibrovascular polyp.
Mallory-Weiss Syndrome
A condition characterized by mucosal tears at the ESOPHAGOGASTRIC JUNCTION, sometimes with HEMATEMESIS. Typically it is caused by forceful bouts of retching or VOMITING.
Zenker Diverticulum
A DIVERTICULUM at the upper end of the ESOPHAGUS through the cricopharyngeal muscle at the junction of the PHARYNX and the esophagus.
About the K22 Code Range
These conditions affect the esophagus, or food pipe. They include ulcers, obstruction, perforation, movement disorders, acquired pouches, tears with bleeding, and polyps.
Within K22, esophageal ulcers split by whether bleeding is present: K22.10 without bleeding and K22.11 with bleeding. Barrett's esophagus splits by whether dysplasia is present. Codes for dysplasia then distinguish low grade, high grade, and unspecified grade. The polyp codes distinguish the esophagus from the junction between the esophagus and stomach. Other branches identify specific conditions or an unspecified esophageal disease.
