Poisoning by other and unspecified hormones and synthetic substitutes

This code signifies an adverse reaction or toxic effect resulting from the ingestion, exposure, or administration of hormones or synthetic hormonal substances not otherwise specified. It covers cases where the specific hormone involved is unknown or falls outside more detailed categories.

Use this code when documentation indicates poisoning by a hormone or synthetic substitute, and a more specific ICD-9-CM code for the particular hormone is unavailable or the substance is explicitly described as "unspecified." This is often seen in emergency department visits or toxicology reports where the exact agent is still being identified or is a general hormonal preparation.

• Always attempt to identify the specific hormone involved for more precise coding (e.g., estrogens, androgens, corticosteroids).
• This code should be sequenced as a primary diagnosis when the poisoning is the reason for the encounter, followed by codes for any manifestations.
• Ensure documentation clearly states "poisoning" or "adverse effect" due to a hormonal substance, rather than a therapeutic adverse effect of a properly administered drug.
