Accidental drown while in natural water, sequela

This code signifies the long-term health consequences or complications arising from an accidental drowning or near-drowning incident that occurred in a natural body of water (e.g., ocean, lake, river). These sequelae can manifest as chronic respiratory issues, neurological deficits, cognitive impairments, or other persistent conditions directly attributable to the initial hypoxic event.

Apply this code when documenting a patient's current medical condition that is a direct result of a past accidental drowning or submersion in a natural water environment. This is appropriate for follow-up care, rehabilitation, or ongoing management of chronic conditions stemming from such an event, even if the initial drowning occurred years prior.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., anoxic brain damage, chronic lung disease).
• Ensure documentation clearly links the current condition to the past accidental drowning in natural water.
• This code is for sequelae only; do not use it for the initial acute drowning event.
