Toxic effect of venom of black widow spider, acc, init

This code signifies the adverse health effects resulting from an unintentional bite by a black widow spider. It specifically applies to the initial phase of treatment for the systemic or localized toxic reactions caused by the spider's venom.

Use this code for patients presenting to an emergency department or physician's office for the first time following an accidental black widow spider bite. This includes symptoms such as muscle cramps, abdominal pain, hypertension, or localized pain and swelling at the bite site.

• Ensure documentation clearly states the bite was accidental and not intentional (e.g., self-harm).
• Confirm the encounter is the initial one for this specific injury; subsequent encounters will require a different seventh character.
• Always code any specific symptoms or manifestations of the envenomation in addition to this code.
