Poisoning by heroin, intentional self-harm, sequela

This code signifies the long-term effects or complications arising from a past intentional overdose or self-poisoning with heroin. It indicates that the patient is now presenting with a condition directly attributable to that prior self-harm event, rather than the acute poisoning itself.

Apply this code when documenting conditions such as chronic organ damage, neurological deficits, or persistent mental health issues that are sequelae of a previously treated heroin self-poisoning. This code is appropriate for follow-up encounters occurring after the acute phase of the poisoning has resolved.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past intentional heroin overdose.
• Do not use this code for acute poisoning events; instead, refer to the appropriate acute poisoning codes.
