Unsp drowning and submersion, undetermined intent, subs

This code signifies a follow-up encounter for a patient who experienced an unspecified drowning or submersion event where the intent (accidental, self-harm, assault) could not be determined. It indicates that the patient is receiving ongoing care or evaluation related to the initial incident.

Use this code for subsequent visits when a patient is being treated for complications, sequelae, or ongoing monitoring related to a drowning or submersion event of undetermined intent. This includes follow-up appointments for respiratory issues, neurological deficits, or psychological distress stemming from the initial incident.

• Always assign an external cause code (V, W, X, Y codes) as a secondary diagnosis to provide more specificity about the circumstances of the injury.
• Ensure documentation clearly supports that the intent of the drowning/submersion remains undetermined for this code to be appropriate.
• Verify that the encounter is indeed "subsequent" and not an initial encounter for the injury.
