Poisoning by unsp hormone antagonists, accidental, subs

This code signifies an accidental poisoning event involving an unknown or unspecified medication that works by blocking the action of hormones. The "subsequent encounter" indicates that the patient is receiving follow-up care for the initial poisoning, such as monitoring for lingering effects or managing complications.

Apply this code when a patient presents for ongoing treatment or evaluation after an accidental overdose or adverse reaction to an unspecified hormone antagonist. This could include follow-up appointments for liver function tests, electrolyte monitoring, or management of persistent symptoms stemming from the initial poisoning.

• Ensure documentation clearly states the poisoning was accidental and the substance was an unspecified hormone antagonist.
• The "D" seventh character is crucial and indicates a subsequent encounter for care related to the initial poisoning.
• Do not use this code for initial encounters or for sequelae (late effects) of the poisoning.
