Toxic effect of cobra venom, undetermined, initial encounter

This code signifies a patient presenting with adverse health effects resulting from exposure to cobra venom, where the intent (accidental, intentional self-harm, assault) of the exposure cannot be determined at the time of the initial encounter. The patient is experiencing the acute, direct physiological consequences of the venom.

Apply this code when a patient is admitted or seen for the first time due to symptoms of cobra envenomation, and the circumstances surrounding the exposure are unclear or undocumented. This is appropriate for the initial assessment and treatment phase of the toxic effect.

• Always assign an additional code for the specific signs and symptoms or other manifestations of the cobra envenomation.
• Do not use this code if the intent of the exposure is known (e.g., accidental, intentional self-harm, assault); instead, select the appropriate intent-specific code.
• For subsequent encounters for the same envenomation, use the appropriate "subsequent encounter" or "sequela" seventh character.
