Toxic effect of venom of black widow spider, slf-hrm, sqla

This code signifies the long-term or residual effects resulting from a black widow spider envenomation that was intentionally self-inflicted. These sequelae could include chronic pain, neurological deficits, or persistent skin lesions that are directly attributable to the original toxic exposure. The "S" seventh character indicates that this is a late effect of the initial injury.

Apply this code when documenting conditions or symptoms that are a direct consequence of a black widow spider bite, where the patient deliberately caused the envenomation, and the encounter is for treatment of these lasting effects. This would be used for follow-up visits or ongoing management of chronic issues stemming from the self-harm incident, occurring after the acute phase of the envenomation has passed.

• Always assign an additional code for the specific sequela being treated (e.g., chronic pain, neuropathy).
• Ensure documentation clearly links the current condition to the past intentional black widow spider envenomation.
• This "S" seventh character is only used for encounters addressing the sequelae, not the initial acute toxic effect.
