Oth foreign object in esophagus causing oth injury, subs

This code signifies a patient presenting with an injury to the esophagus caused by a foreign object, other than a burn or corrosion, during a subsequent encounter for this condition. The foreign object itself is no longer present or is not the primary focus of the current encounter, but the esophageal injury it caused is still being treated.

This code is appropriate for follow-up visits where a patient is being monitored or treated for complications or ongoing effects of an esophageal injury previously caused by an ingested foreign body. Examples include managing inflammation, stricture formation, or persistent pain after the foreign object has been removed. It should be used when the initial injury has already been addressed and the current encounter focuses on its aftermath.

• Requires a seventh character "D" for subsequent encounter.
• Do not use if the foreign object is still present and causing the primary issue; refer to acute foreign body codes.
• Always code the specific nature of the esophageal injury (e.g., esophagitis, perforation) as a secondary diagnosis if known.
