Toxic effect of unsp snake venom, assault, subs encntr

This code signifies a patient presenting for follow-up care or treatment of complications arising from a snakebite where the specific type of snake venom is unknown. The bite was intentionally inflicted by another person, indicating an assault.

Apply this code for subsequent encounters related to the management of a snakebite injury resulting from an assault, when the venom type was not identified at the time of the initial encounter. This includes scenarios such as wound care, monitoring for delayed systemic effects, or addressing psychological sequelae.

• Ensure documentation clearly states the encounter is subsequent and the snake venom was unspecified.
• Verify the intent of the bite was an assault; otherwise, a different external cause code is needed.
• Always sequence this code after the primary diagnosis for the specific effects of the snakebite.
