Gastric contents in pharynx causing asphyxiation, sequela

This code describes the long-term or delayed effects resulting from a past event where gastric contents entered the pharynx, leading to asphyxiation. It signifies that the patient is currently experiencing a health problem directly attributable to this prior aspiration incident.

Use this code when documenting a patient presenting with a chronic condition or complication that is a direct consequence of a previous aspiration of stomach contents into the pharynx, which caused asphyxiation. This applies to follow-up encounters for persistent issues rather than the initial acute event.

• Requires a seventh character "S" to indicate sequela, meaning a complication or condition arising as a direct result of an injury or disease.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic aspiration pneumonia, esophageal stricture).
• Ensure documentation clearly links the current condition to the past gastric contents aspiration with asphyxiation.
