Gastric contents in trachea causing asphyxiation, subs

This code signifies a patient presenting for follow-up care related to an episode of asphyxiation caused by the aspiration of gastric contents into the trachea. It indicates that the initial event has already been treated, and the current encounter addresses ongoing management, complications, or sequelae.

Apply this code when a patient returns for subsequent evaluation or treatment after an initial aspiration event involving gastric contents led to asphyxiation. This could include monitoring for aspiration pneumonia, managing respiratory complications, or addressing other lingering effects of the initial incident.

• Requires a seventh character of 'D' for subsequent encounter.
• Do not use for the initial treatment of the aspiration event; refer to the 'A' (initial encounter) character for that.
• Code any associated complications, such as aspiration pneumonia, separately.
