Oth foreign object in pharynx causing asphyxiation, sequela

This code describes the long-term or late effects resulting from a foreign object in the pharynx that previously caused a lack of oxygen. These sequelae could include chronic respiratory issues, neurological damage, or other persistent health problems directly attributable to the past asphyxiation event.

Apply this code when documenting conditions that are a direct consequence of a past episode of asphyxiation due to a foreign object lodged in the pharynx. This is appropriate for follow-up encounters where the patient is being treated for the residual effects, not the acute event itself.

• 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 asphyxiation event.
• A seventh character "S" indicates sequela, meaning the patient is being treated for the residual effects of the original injury.
