Drown while in bathtub, undetermined intent, sequela

This code signifies the long-term effects or complications resulting from a drowning or submersion incident that occurred in a bathtub, where the intent of the event (accidental, self-harm, assault) could not be determined. It indicates that the patient is presenting for treatment of a condition directly attributable to this past, undetermined-intent bathtub submersion.

Use this code when documenting follow-up care for a patient experiencing sequelae such as anoxic brain injury, aspiration pneumonia, or other chronic conditions directly linked to a prior drowning or submersion event in a bathtub, and the intent of that event was not definitively established. This applies to situations where the initial acute event has passed, and the patient is now being treated for the lasting consequences.

• Always assign an external cause code (V00-Y99) to provide additional context regarding the circumstances of the injury.
• Ensure documentation clearly links the current condition to the past drowning/submersion event and specifies the "sequela" nature of the encounter.
• Verify that the intent of the original incident was explicitly documented as "undetermined" to support the use of this specific code.
