Other drowning and submersion, undetermined intent, sequela

This code signifies the long-term effects or complications arising from a past drowning or submersion incident where the intent (accidental, self-harm, assault) could not be determined. It is used to report conditions that are residual to the original event, such as chronic respiratory issues, neurological deficits, or cognitive impairments.

Apply this code when documenting a patient presenting with a current health problem directly attributable to a previous, unspecified drowning or submersion event. This is appropriate for follow-up care or rehabilitation for conditions like anoxic brain injury or persistent lung damage that occurred as a result of the initial incident.

• Always sequence this code after the code for the specific sequela being treated (e.g., anoxic brain damage).
• Ensure documentation clearly links the current condition to the past drowning/submersion and states the undetermined intent.
• Do not use for acute drowning events; this code is exclusively for sequelae.
