Poisoning by unsp hormone antagonists, self-harm, sequela

This code signifies a long-term consequence or complication arising from an intentional self-harm attempt involving an unspecified hormone antagonist. The initial poisoning event has already occurred and resolved, but the patient is now presenting with a residual effect directly attributable to that past event.

Apply this code when documenting a sequela (e.g., organ damage, chronic neurological deficits, psychological issues) that is a direct result of a previous self-inflicted poisoning by an unspecified hormone antagonist. This code is appropriate for encounters where the focus is on managing or treating these lasting effects, not the acute poisoning itself.

• 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 self-harm by an unspecified hormone antagonist.
• Do not use this code for acute poisoning events; use the appropriate acute poisoning code with the initial encounter (A) or subsequent encounter (D) seventh character.
