Poisn by fentanyl or fentanyl analogs, self-harm, sequela

This code signifies the long-term or residual effects resulting from a deliberate act of self-poisoning with fentanyl or its analogs. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience health problems directly attributable to that event. These sequelae can be physical, neurological, or psychological.

Apply this code when documenting a patient presenting with chronic conditions, disabilities, or persistent symptoms that are a direct consequence of a past intentional self-harm attempt involving fentanyl. This would include conditions like anoxic brain injury, chronic organ damage, or persistent neurological deficits stemming from the overdose. It is used after the acute poisoning has been treated and the patient is being managed for the lasting effects.

• Always sequence this sequela code after the code describing the specific residual condition(s) being treated.
• Ensure documentation clearly links the current sequela to a past intentional fentanyl self-harm event.
• Do not use this code for the initial acute poisoning encounter; instead, use the appropriate acute poisoning code with the 7th character 'A' or 'D'.
