Food in esophagus causing other injury, sequela

This code signifies a long-term or residual effect resulting from a past episode where food became lodged in the esophagus, leading to an injury other than a complete obstruction. This could include chronic inflammation, stricture formation, or other persistent damage to the esophageal tissue.

Apply this code when documenting a patient presenting with ongoing symptoms or conditions directly attributable to a previous esophageal injury caused by food impaction. This is appropriate for follow-up visits addressing the sequelae, rather than the acute event itself.

• Ensure documentation clearly links the current condition to a past esophageal food impaction.
• Do not use this code for acute food impaction or complete esophageal obstruction; those have different codes.
• Always assign with an additional code(s) to specify the exact nature of the other injury or sequela (e.g., K22.2 for esophageal obstruction, K22.3 for perforation).
