Toxic effect of venom of brown recluse spider, slf-hrm, subs

This code signifies a patient presenting with symptoms resulting from the venom of a brown recluse spider, where the exposure was deliberately self-inflicted. The encounter is not the initial presentation for this specific injury. The clinical picture may include localized skin necrosis, pain, and systemic symptoms like fever or malaise, all stemming from the spider's bite.

Use this code for follow-up visits related to a brown recluse spider envenomation that the patient intentionally caused, such as a patient returning for wound care, medication adjustments, or monitoring of systemic effects after the initial treatment. It applies when the intent of the bite was self-harm, not accidental or assault.

• Ensure documentation clearly specifies "intentional self-harm" and "subsequent encounter."
• Always sequence this code after the primary mental health diagnosis if the self-harm is related to a psychiatric condition.
• Verify the spider species is explicitly documented as "brown recluse" to avoid miscoding with other spider bites.
