Toxic effect of venom of bees, undetermined, sequela

This code signifies the long-term or residual effects resulting from a bee venom exposure where the intent (accidental, intentional self-harm, assault) of the exposure is unknown. These sequelae can include chronic pain, persistent allergic reactions, neurological deficits, or organ damage that manifest after the acute phase of the envenomation has passed.

Apply this code when documenting conditions that are direct, lasting consequences of a bee sting, and the provider cannot determine if the exposure was accidental, intentional, or due to assault. This is appropriate for follow-up encounters addressing these chronic issues, not for the initial acute treatment of the sting itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic urticaria, peripheral neuropathy).
• Ensure documentation clearly links the current condition to a past bee venom exposure and explicitly states the undetermined intent.
• The "S" seventh character indicates a sequela, meaning it's for conditions arising from the initial injury or poisoning.
