Toxic effect of unsp snake venom, undetermined, subs encntr

This code signifies a patient presenting for follow-up care or rehabilitation after an exposure to an unspecified snake venom, where the intent (accidental, intentional self-harm, assault) of the exposure is not documented. The patient is no longer in the acute phase of treatment for the toxic effects.

Use this code for patients returning for wound care, physical therapy, or monitoring of long-term effects following an unspecified snakebite. This applies when the initial encounter for the acute poisoning has concluded, and the circumstances surrounding the bite remain unclear.

• Always sequence this code after the primary diagnosis for the specific toxic effect or complication being treated.
• Ensure documentation clearly indicates a "subsequent encounter" and that the snake species and intent are unspecified.
• Avoid using this code for initial treatment of an acute snake envenomation; use the appropriate acute phase code instead.
