Toxic effect of venom of N & S American snake, slf-hrm, init

This code signifies a patient presenting with adverse systemic effects resulting from self-inflicted exposure to venom from a North or South American snake species not otherwise specified. The patient intentionally caused the envenomation, and this encounter represents the initial treatment for the toxic effects.

Apply this code when documentation clearly indicates a patient intentionally exposed themselves to venom from an unspecified North or South American snake, leading to a toxic reaction. This is appropriate for the initial hospital visit or emergency department encounter where the acute effects are being managed.

• Always confirm the intent was self-harm; otherwise, a different intent code (e.g., accidental, assault) would be more appropriate.
• Ensure the snake is identified as a North or South American species, but not a specific type (e.g., rattlesnake, coral snake) for which a more precise code exists.
• This "A" initial encounter seventh character is used for the period of active treatment for the toxic effect.
