Toxic effect of contact w oth venom fish, assault, sequela

This code signifies a long-term or residual health problem resulting from a past assault involving contact with a venomous fish other than those specifically classified elsewhere. These sequelae could include chronic pain, nerve damage, scarring, or persistent functional limitations directly attributable to the original envenomation. The "assault" component indicates the injury was intentionally inflicted by another person.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of a previous, intentional injury from a venomous fish. This is appropriate for follow-up visits or when the sequela is the primary reason for the encounter, long after the acute phase of the original injury has passed.

• Always use this code as a secondary diagnosis, following a code for the specific sequela (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to the past venomous fish assault.
• Verify the "assault" intent; if accidental, a different external cause code would be appropriate.
