Poisoning by unsp hormone antagonists, undetermined, sequela

This code signifies a long-term health problem or complication resulting from an undetermined poisoning by an unspecified hormone antagonist. The initial poisoning event's circumstances (accidental, intentional self-harm, assault, etc.) could not be determined, and the specific hormone antagonist involved is unknown. The sequela represents the lasting effects of this past poisoning.

Apply this code when documenting a chronic condition or residual effect directly attributable to a past poisoning by an unknown hormone antagonist, where the intent of the poisoning is also unknown. This is appropriate for follow-up encounters addressing these persistent health issues, long after the acute poisoning episode has resolved.

• Always sequence this code after the code(s) for the specific sequela (e.g., organ damage, neurological deficits).
• Ensure documentation clearly links the current condition to a past, undetermined poisoning by an unspecified hormone antagonist.
• Avoid using this code for acute poisoning events; it is exclusively for sequelae.
