Toxic effect of venom of arthropod, self-harm, sequela

This code signifies a long-term consequence or complication arising from a deliberate act of self-poisoning using venom from an arthropod other than a spider, scorpion, or bee. It indicates that the initial toxic exposure has resolved, but the patient is still experiencing residual effects.

Apply this code when documenting a follow-up visit for a patient who intentionally self-harmed with an unspecified arthropod venom, and is now presenting with chronic or residual symptoms directly attributable to that past event. Examples include persistent neurological deficits, organ damage, or chronic pain syndromes resulting from the initial poisoning.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past intentional self-harm by arthropod venom.
• Do not use for acute toxic effects; this code is exclusively for sequelae.
