Assault by drowning and submersion, unspecified, sequela

This code signifies long-term health problems or conditions that are a direct result of an unspecified assault involving drowning or submersion. It indicates that the initial traumatic event has passed, but its lasting effects are now being treated or evaluated. The specific nature of the assault or the method of drowning/submersion is not detailed.

Use this code when documenting and billing for the treatment of residual conditions, such as neurological deficits, respiratory complications, or psychological trauma, that are directly attributable to a past assault by drowning or submersion. This applies when the patient is presenting for care related to these chronic sequelae, not the initial acute injury.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., anoxic brain injury, aspiration pneumonia).
• Ensure documentation clearly links the current condition to a past assault by drowning or submersion.
• The "S" seventh character indicates sequela and should be used for all encounters related to the long-term effects.
