Poisoning by cocaine, undetermined, sequela

This code signifies a past event of cocaine poisoning where the intent (accidental, intentional self-harm, assault) could not be determined. It is used when a patient presents with a condition or complication that is a direct result or sequela of that prior poisoning. This indicates that the acute phase of the poisoning is over, but its effects are still being managed.

Apply this code when a patient is being treated for a long-term effect or complication directly attributable to a previous cocaine poisoning of undetermined intent. Examples include chronic organ damage, neurological deficits, or mental health conditions that developed as a consequence of the poisoning. This code is appropriate for follow-up care related to the poisoning's lasting impact.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past cocaine poisoning and specifies the undetermined intent.
• Verify that the "S" seventh character is appropriate, indicating a sequela, and not an acute or subsequent encounter for the poisoning itself.
