Toxic effect of venom of brown recluse spider, acc, init

This code signifies the adverse systemic or localized effects resulting from an unintentional bite by a brown recluse spider. These effects can range from localized tissue necrosis and ulceration to, in rare cases, more severe systemic reactions. The "initial encounter" designation indicates that the patient is receiving active treatment for the acute phase of the injury.

Apply this code when a patient presents with symptoms directly attributable to a brown recluse spider bite, and the bite was not intentionally inflicted. This includes scenarios where a patient was unaware of the spider's presence, such as being bitten while sleeping or reaching into an unseen area. It is appropriate for the initial visit where diagnosis and treatment of the acute toxic effects are being managed.

• Ensure documentation clearly states "brown recluse spider" and that the bite was accidental.
• Do not use for bites from other spider species; specific codes exist for other venomous spiders.
• Remember to also code any specific manifestations or complications of the toxic effect, such as cellulitis or tissue necrosis.
