Unsp drowning and submersion, undetermined intent, sequela

This code signifies the long-term effects or complications arising from an incident of drowning or submersion where the intent (accidental, self-harm, assault) could not be determined. It is used when the patient presents with residual health issues directly attributable to a past, unspecified drowning event.

Apply this code when documenting a patient's current medical condition that is a direct consequence of a previous drowning or submersion incident of unknown intent. This would include conditions like anoxic brain injury, chronic respiratory issues, or neurological deficits that manifest after the initial acute phase of the event.

• Only use this code for sequelae, not for the initial acute drowning event.
• Ensure documentation clearly links the current condition to a past drowning of undetermined intent.
• Always code the specific sequela first, followed by this code as an external cause.
