Poisoning by oth hormone antagonists, accidental, sequela

This code indicates a long-term consequence or complication arising from an accidental overdose or adverse reaction to a hormone antagonist medication not specified elsewhere. It signifies that the initial poisoning event has resolved, but the patient continues to experience residual effects directly attributable to that unintentional exposure.

Use this code when documenting a chronic condition, disability, or other lasting health problem that is a direct result of a past accidental poisoning by an unspecified hormone antagonist. This applies to follow-up encounters for conditions like persistent organ damage, neurological deficits, or endocrine imbalances that developed after the acute poisoning episode.

• 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 accidental poisoning by a hormone antagonist.
• Do not use for acute poisoning events; this code is exclusively for the long-term effects.
