Poisn by unsp prim sys and hematolog agent, slf-hrm, sequela

This code signifies a long-term consequence or complication arising from a prior act of intentional self-poisoning with an unspecified substance that primarily affects the body's systems and blood. It indicates that the acute phase of the poisoning has passed, but the patient is still experiencing residual effects directly attributable to that self-harm event.

Use this code when documenting follow-up care for a patient who previously attempted suicide via poisoning with a systemic or hematological agent, and who is now presenting with chronic or persistent health issues stemming from that incident. This applies to situations where the specific agent is unknown or not documented, and the focus is on the sequelae.

• Ensure the medical record clearly links the current condition to a past self-harm poisoning event.
• This "S" seventh character indicates a sequela, meaning the residual effects of a past injury or condition.
• Do not use for acute poisoning events; those require codes with "A" or "D" seventh characters.
