Toxic effect of unsp snake venom, self-harm, sequela

This code signifies a long-term health problem or residual effect stemming from a previous act of intentional self-poisoning with unspecified snake venom. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience lasting complications directly attributable to that event. These sequelae could manifest as chronic organ damage, neurological deficits, or other persistent health issues.

Use this code when documenting a patient presenting with a current condition that is a direct, lasting consequence of a past intentional self-harm event involving unspecified snake venom. This applies when the original poisoning occurred in the past and the current encounter is for managing or treating these chronic, residual effects. It is not for the acute poisoning event itself.

• Always sequence this sequela code after the code for the specific nature of the sequela (e.g., chronic kidney disease, peripheral neuropathy).
• Ensure documentation clearly links the current condition to the past intentional self-harm by snake venom.
• Do not use this code for acute poisoning or for accidental exposures; specific codes exist for those scenarios.
