Unsp foreign body in pharynx causing asphyxiation, sequela

This code describes the long-term or residual effects resulting from an unidentifiable foreign object in the pharynx that previously led to a lack of oxygen. These sequelae could include chronic respiratory issues, neurological damage, or other lasting complications directly attributable to the past asphyxiation event.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of a past episode of asphyxiation caused by an unspecified foreign body in the pharynx. This code is appropriate for follow-up care or when the patient is seen for the chronic effects after the acute event has resolved.

• 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 caused by an unspecified foreign body.
• Do not use for acute foreign body aspiration; this code is exclusively for sequelae.
