ICD-10 Code K94.3 – Esophagostomy complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K94.3 – Esophagostomy complications
What it is
K94.3 identifies complications involving an esophagostomy, an opening created into the esophagus. Use it when documentation states the stoma or surgical site has a complication, not simply that the procedure was performed.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include leakage, irritation, infection, obstruction, or breakdown at the esophagostomy site.
When to use this code
Use K94.3 when the provider documents a complication directly related to the esophagostomy and the record does not identify a more specific complication code. It is appropriate for postoperative or ongoing stoma problems clearly linked to the esophagostomy. Check documentation if the note only describes routine care or the presence of the stoma.
Do not use for
Do not use this code for uncomplicated esophagostomy care or for symptoms not tied to the stoma. If the complication is better described by another diagnosis, code that condition instead.
Coding tip
Look for explicit provider wording that the problem is a complication of the esophagostomy before assigning K94.3.
