Y42: Hormones and their synthetic substitutes and antagonists, not elsewhere classified

Y42.9: Other and unspecified hormone antagonists

The condition coded as Y42.9 in the ICD-10 classification refers to health issues caused by other and unspecified hormone antagonists. These are drugs used to counteract the effects of hormones in the body and can potentially cause side effects or adverse reactions. This condition occurs when an individual experiences a negative response to such medications, which might present symptoms such as hormone imbalance, fatigue, mood swings, weight changes, and other issues depending on the specific hormone being targeted by the drug. It is important to note that the severity and type of symptoms can vary widely based on the individual's overall health, the type of hormone antagonist used, and the length of treatment. This condition does not directly result from a disease or illness but from the interaction between a medication and the individual's body. It may affect multiple systems in the body, depending on the hormone that the drug is blocking or inhibiting.
