Toxic effect of contact w venomous toad, undet, sequela

This code signifies a long-term health problem or complication arising from a past exposure to a venomous toad, where the intent (accidental, intentional self-harm, assault) of the exposure was not determined at the time of the initial encounter. These sequelae can manifest as chronic neurological issues, persistent dermatological conditions, or other lasting systemic effects.

Apply this code when documenting a patient presenting with a current, ongoing condition directly attributable to a venomous toad exposure that occurred in the past, and the original encounter did not specify the intent of the exposure. This is appropriate for follow-up visits addressing the chronic consequences rather than the acute poisoning.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past venomous toad exposure with undetermined intent.
• Do not use for acute toxic effects; this code is exclusively for residual conditions.
