ICD-10 Code K94.33 – Esophagostomy malfunction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K94.33 – Esophagostomy malfunction
What it is
K94.33 identifies a malfunction of an esophagostomy, meaning the surgically created opening in the esophagus is not working as intended. Use this code when documentation states the stoma or its function has failed or become impaired.
Clinical signs
Clinical features vary; refer to documentation. You may see leakage, obstruction, displacement, or difficulty using the esophagostomy for feeding or drainage, depending on the recorded problem.
When to use this code
Use K94.33 when the provider documents an esophagostomy malfunction, including problems with the stoma itself or its function. It is appropriate when the note clearly identifies malfunction rather than a routine postoperative status. If the chart only says “complication” without specifics, check documentation.
Do not use for
Do not use this code for a normal esophagostomy without complications or for unrelated esophageal disease. If the issue is infection, bleeding, or another distinct complication, code that condition instead when documented.
Coding tip
Code only when the record links the problem to the esophagostomy and names malfunction; otherwise, query for clarification.
