Asphyx due to smothering under pillow, undetermined, subs

This code describes a case of asphyxiation resulting from smothering with a pillow, where the intent (accidental, suicidal, or homicidal) cannot be determined. This specific code is used for encounters following the initial treatment of the asphyxiation.

Apply this code when a patient presents for follow-up care, rehabilitation, or management of complications stemming from an undetermined smothering incident involving a pillow. This includes situations where the patient is recovering from the acute event or experiencing long-term effects.

• Ensure documentation clearly states "undetermined" intent for the smothering.
• Confirm this is a subsequent encounter, not the initial presentation for the acute event.
• Look for associated sequelae or ongoing care related to the asphyxiation.
