Poisn by antigonadtr/antiestr/antiandrg, NEC, acc, sequela

This code signifies a long-term consequence or complication arising from an accidental overdose or exposure to antigonadotrophins, antiestrogens, or antiandrogens. These medications are typically used to modulate hormone levels, and their unintentional ingestion can lead to various lasting health issues. The "sequela" indicates that the acute poisoning event has passed, but its effects persist.

Apply this code when documenting a patient presenting with a chronic condition or residual symptom directly attributable to a past, accidental poisoning by one of the specified hormone-modulating agents. Examples include persistent endocrine dysfunction, organ damage, or neurological deficits that developed as a result of the initial unintentional exposure. This code is not for the acute poisoning event itself.

• Ensure documentation clearly links the current condition to a past accidental poisoning by antigonadotrophins, antiestrogens, or antiandrogens.
• Do not use this code for intentional self-harm or assault; those scenarios require different intent codes.
• Always code the specific sequela (e.g., chronic liver failure, persistent hypogonadism) first, followed by this external cause code.
