Drown after fall into swimming pool, undet intent, subs

This code describes a patient presenting for follow-up care related to an incident where they fell into a swimming pool and subsequently drowned or were submerged. The circumstances surrounding the fall and submersion are unclear, meaning it cannot be definitively classified as accidental, self-harm, or assault.

Use this code for subsequent encounters (e.g., follow-up appointments, rehabilitation sessions) for a patient who experienced drowning or submersion after an unclarified fall into a swimming pool. This applies when the initial injury has already been treated, and the patient is receiving ongoing care related to the event.

• Ensure the encounter is for follow-up care, not the initial treatment of the injury.
• Verify documentation explicitly states the fall was into a swimming pool and the intent is undetermined.
• Do not use if the intent (e.g., accidental, self-harm) is clearly documented.
