Toxic effect of venom of reptiles, accidental, sequela

This code signifies a long-term or late-onset health problem resulting from an accidental envenomation by a reptile other than a snake or lizard. These sequelae are persistent conditions that arise after the initial acute toxic effects have resolved. Examples include chronic pain, tissue necrosis, or neurological deficits attributable to the original venom exposure.

Apply this code when documenting a patient presenting with a residual condition directly linked to an unintentional toxic effect from a reptile bite (excluding snakes and lizards) that occurred in the past. This is appropriate for follow-up encounters addressing these lasting complications, not the initial acute injury.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela.
• Ensure documentation clearly links the current condition to a past reptile envenomation.
• Do not use for initial acute toxic effects; this code is exclusively for sequelae.
