Which CPT code corresponds to the plastic repair of a tracheoesophageal fistula?

• A. 43110
• B. 43305
• C. 43205
• D. 43450

Answer: (B)

The key idea is matching the surgery performed to the CPT code that explicitly describes repairing a connection between the trachea and esophagus. A plastic repair of a tracheoesophageal fistula is a dedicated repair of that abnormal fistulous tract, so the correct code is the one that specifically denotes repair of a tracheoesophageal fistula. This code aligns precisely with the operation’s nature—surgical closure of the fistula between airway and esophagus, typically using tissue rearrangement or interposition as needed. The other codes describe procedures that are not the isolated TE fistula repair (they may cover esophageal endoscopy, different esophageal or airway reconstructions, or non-fistula repairs), so they don’t capture the service performed. Documentation should reflect the repair approach (primary repair vs. repair with graft/flap) to ensure the most accurate coding.
