Food in larynx causing asphyxiation, sequela

This code signifies the long-term or residual effects resulting from a past episode of food obstructing the larynx, which led to asphyxiation. These sequelae can manifest as chronic respiratory issues, neurological damage due to hypoxia, or other persistent health problems directly attributable to the initial event.

This code is appropriate for documenting conditions that are a direct consequence of a previous aspiration of food into the larynx, leading to asphyxiation. It should be used when the acute event has resolved, but the patient continues to experience related health problems. Examples include chronic aspiration pneumonia, vocal cord dysfunction, or anoxic brain injury stemming from the original incident.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past episode of food aspiration and asphyxiation.
• Do not use this code for the initial acute event; instead, use the appropriate acute injury code.
