Toxic effect of unspecified snake venom, assault, sequela

This code signifies a long-term consequence or complication arising from a previous toxic exposure to an unspecified snake's venom, specifically when the exposure was the result of an assault. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual effects.

Apply this code when documenting a patient presenting with chronic or permanent conditions directly attributable to a past snake venom exposure that occurred due to an intentional act of harm. This would include scenarios where a patient is being treated for ongoing neurological deficits, organ damage, or other lasting sequelae from such an event.

• Always ensure documentation clearly links the current sequela to the past snake venom exposure and specifies the assault as the external cause.
• Do not use for acute toxic effects; this code is exclusively for sequelae.
• An additional code for the specific sequela (e.g., neurological deficit, organ damage) should be reported first, followed by this code to indicate the etiology.
