    ICD-10-CM Code For Other Diseases Of Esophagus: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K22 includes diagnoses affecting the esophagus such as diverticulum, stricture, web, mucosal disorders, and other structural or functional abnormalities. These ICD-10-CM diagnosis codes are used to document conditions that impair swallowing, cause obstructive or inflammatory esophageal disease, or require procedures or medical management, capturing disease severity and organ involvement. Accurate coding within the ICD-10-CM K22 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM K22: Other Diseases Of Esophagus Overview

    The ICD-10-CM K22 group includes a set of diagnoses that affect the structure and function of the esophagus, such as diverticula, webs, strictures, and motility disorders. These conditions target the alimentary tract, specifically the esophagus, and can impact swallowing, nutrition, and airway safety. Accurate coding matters because it supports clinical communication, correct claim processing by payers, and documentation of disease severity for care planning.

    When to Use

    Use a code from this group when a patient has a documented diagnosis of an esophageal condition such as diverticulum, stricture, web, or a specified motility or mucosal disorder that is not classified elsewhere. Select the most specific code available to reflect the documented diagnosis, clinical severity, and any associated complications.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with sudden-onset severe odynophagia, drooling, and inability to swallow after ingestion of a caustic substance; endoscopy shows full-thickness esophageal injury and mucosal necrosis. This acute, potentially life-threatening presentation requires immediate evaluation and the clinician assigns an acute esophageal injury diagnosis based on endoscopic findings and history of corrosive ingestion. Typical codes: K22.6, K22.4
    • A middle-aged patient with long-standing gastroesophageal reflux disease reports progressive dysphagia to solids and intermittent regurgitation; evaluation including barium swallow and endoscopy reveals a benign esophageal stricture from chronic reflux. This chronic, structural complication of reflux is managed as an ongoing condition and the provider assigns a code indicating esophageal stricture to document the functional obstruction and guide therapy. Typical codes: K22.2, K22.81
    • An inpatient with head and neck cancer undergoing radiation therapy develops persistent severe dysphagia and documented esophageal ulceration and scarring causing weight loss and need for enteral nutrition; the esophageal condition is coded as a treatment-related complication and coexisting disease impacting care. Typical codes: K22.3, K22.89
