Asphyx due to being trapped in a car trunk, undet, sequela

This code describes the long-term effects or complications arising from an asphyxiation event where the cause of being trapped in a car trunk is undetermined. It signifies that the patient is experiencing residual health problems directly attributable to this past incident.

This code is appropriate for documenting follow-up care or chronic conditions resulting from a previous, undetermined asphyxiation due to being trapped in a car trunk. It should be used when the acute phase of the injury has passed, and the patient is being treated for sequelae.

• Always use in conjunction with a code describing the specific sequela (e.g., anoxic brain injury, chronic respiratory failure).
• Requires a seventh character "S" to indicate sequela, meaning the patient is seen for complications or conditions arising from the initial injury.
• Do not use for the initial encounter or active treatment of the acute asphyxiation event.
