Asphyx due to smothering in furniture, undetermined, subs

This code describes a case of asphyxiation resulting from smothering by furniture, where the intent (accidental, intentional, or suicidal) cannot be determined. This diagnosis is applied during a follow-up visit after the initial treatment of the asphyxiation event.

Use this code for subsequent encounters when a patient is being treated for complications or sequelae directly related to a previously diagnosed asphyxiation due to smothering by furniture, and the circumstances surrounding the event remain undetermined. This includes follow-up appointments for respiratory issues, neurological damage, or psychological sequelae.

• Ensure documentation clearly states the undetermined intent of the smothering event.
• Confirm this is a subsequent encounter, not the initial treatment for the acute event.
• Code any associated injuries or conditions as additional diagnoses.
