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 2026, 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.
Esophageal Fistula
Abnormal passage communicating with the ESOPHAGUS. The most common type is TRACHEOESOPHAGEAL FISTULA between the esophagus and the TRACHEA.
Moyamoya Disease
A noninflammatory, progressive occlusion of the intracranial CAROTID ARTERIES and the formation of netlike collateral arteries arising from the CIRCLE OF WILLIS. Cerebral angiogram shows the puff-of-smoke (moyamoya) collaterals at the base of the brain. It is characterized by endothelial HYPERPLASIA and FIBROSIS with thickening of arterial walls. This disease primarily affects children but can also occur in adults.
About the K22 Code Range
K22 codes cover a variety of less common conditions affecting the esophagus, ranging from obstructions and ulcers to motility disorders and Barrett's esophagus. These ICD-10 codes are essential for specifying precise diagnoses related to esophageal disease beyond more typical reflux conditions.
The K22.0 code captures achalasia of the cardia, a disorder also known as "absence of peristalsis" or "idiopathic achalasia," characterized by impaired esophageal muscle movement and difficulty swallowing. Ulcers of the esophagus are classified under K22.1, with or without bleeding (K22.10 and K22.11), including causes such as infections, medication, or corrosive injury. Obstruction of the esophagus (K22.2) covers a range of strictures and webs that narrow the esophagus, while perforation (K22.3) refers to esophageal tears or ruptures needing urgent attention. Dyskinesia (K22.4) includes motility disorders like nutcracker esophagus and diffuse spasm. Barrett's esophagus is tracked by codes K22.7 through K22.719, separating cases with or without dysplasia, an important precancerous condition. Acquired diverticula (K22.5) and gastro-esophageal lacerations or hemorrhage (K22.6, known as Mallory-Weiss syndrome) are also specified. Other less common or unspecified esophageal conditions fall under K22.8 and K22.9. These ICD-10 codes for other diseases of esophagus support accurate documentation of complex esophageal disorders for both clinical and billing purposes.
