In simple words: This code is used when someone experiences problems from taking too much, too little, or having a bad reaction to certain hormone-blocking medicines. These medicines affect hormones like estrogen and testosterone.The doctor will use this code along with other codes to describe exactly what happened and why.

This ICD-10-CM code classifies poisoning, adverse effects, or underdosing resulting from antigonadotrophins, antiestrogens, and antiandrogens.It encompasses situations where these medications are involved in unintentional or intentional harm, including accidental ingestion, overdose, or underdosing due to error or deliberate action.The code requires additional codes to specify the manifestation of poisoning and the intent (accidental, self-harm, assault, undetermined).

Example 1: A 60-year-old female patient presents to the emergency department with symptoms of nausea, vomiting, and dizziness after accidentally taking a double dose of tamoxifen., A 45-year-old male patient is admitted to the hospital after intentionally overdosing on an antiandrogen medication in a suicide attempt., A 30-year-old female patient experiences an allergic reaction (rash, hives) following the administration of an antigonadotropin medication during treatment for infertility.

Detailed patient history, including the medication taken (name, dose, route of administration, and time of ingestion), documentation of the patient’s symptoms, results of laboratory tests (if any), and the treatment provided.If intentional, documentation should reflect assessment of suicidality or intent.

** This code is not specific to a single drug, but rather encompasses a class of medications.Always confirm the specific medication involved in the adverse event.Consider using additional codes to specify the exact medication if possible.
