Oth drowning and submersion, undetermined intent, subs

This code signifies a subsequent encounter for a patient who experienced a non-fatal drowning or submersion incident where the intent (accidental, self-harm, assault) could not be determined. The patient is receiving follow-up care for injuries or complications directly related to this event.

Apply this code when a patient presents for ongoing treatment, rehabilitation, or monitoring after an initial drowning or submersion event of unknown intent. This includes follow-up appointments for respiratory issues, neurological deficits, or other sequelae. It is appropriate for any encounter after the initial acute care phase.

• This "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always sequence this code after any specific injury codes (e.g., J69.0 for pneumonitis due to aspiration of food and vomitus) that resulted from the drowning.
• Ensure documentation clearly supports the "undetermined intent" and that the encounter is not for the initial acute treatment.
