Tracheo-esophageal fistula following tracheostomy

This code signifies the development of an abnormal connection between the trachea and the esophagus that occurs as a complication of a prior tracheostomy procedure. This fistula allows for the passage of air and/or gastric contents between the two structures, leading to potential respiratory and gastrointestinal issues.

Apply this code when documentation clearly indicates a patient has developed a tracheo-esophageal fistula directly attributable to a previous tracheostomy. This typically presents with symptoms such as coughing during eating/drinking, recurrent aspiration pneumonia, or air leakage from the tracheostomy site into the esophagus.

• Ensure documentation explicitly links the fistula to the tracheostomy; otherwise, consider other fistula codes.
• Sequence this code after the primary reason for the patient's encounter, if applicable, unless the fistula is the primary reason for admission.
• Do not confuse with congenital tracheo-esophageal fistulas (Q39.1-Q39.2) or fistulas due to other causes.
