Toxic effect of venom of oth reptiles, undetermined, sequela

This code signifies a lasting health problem resulting from exposure to venom from a reptile other than a Gila monster or snake, where the specific type of reptile is unknown. These are long-term effects that persist after the acute phase of the envenomation has resolved.

Use this code when documenting chronic conditions, disabilities, or permanent tissue damage directly attributable to an undetermined reptile venom exposure that occurred in the past. This applies when the patient is presenting for treatment of the residual effects, not the initial poisoning.

• Requires a seventh character 'S' to indicate sequela, meaning the patient is experiencing a late effect of the toxic exposure.
• Do not use for acute envenomation; instead, refer to the acute toxic effect codes for initial encounters.
• Ensure documentation clearly links the current condition to a past, undetermined reptile venom exposure.
