ICD-10 T42 is a used to indicate a diagnosis of poisoning by, adverse effect of and underdosing of antiepileptic, sedative- hypnotic and antiparkinsonism drugs.
The ICD-10 Level 1 Category code T42 encompasses poisoning, adverse effects, and underdosing of antiepileptic, sedative-hypnotic, and antiparkinsonism drugs. This category is critical for documenting incidents related to the misuse or inappropriate administration of these medications, which are commonly prescribed for conditions such as epilepsy, anxiety disorders, and Parkinson's disease. Clinicians must be vigilant in recognizing the signs of poisoning or adverse effects, as these can lead to severe complications, including respiratory depression, altered mental status, or exacerbation of the underlying condition being treated. Accurate coding under T42 ensures that healthcare providers can effectively communicate the severity and nature of these incidents, facilitating appropriate management and intervention strategies.

T42 covers conditions related to poisoning, adverse effects, and underdosing of antiepileptic drugs (such as phenytoin and valproate), sedative-hypnotic medications (like benzodiazepines), and antiparkinsonism drugs (including levodopa and dopamine agonists).
T42 codes should be used when a patient presents with symptoms or complications resulting from the misuse, adverse effects, or underdosing of the specified drug categories. This includes cases of overdose, withdrawal symptoms, or ineffective treatment due to inadequate dosing.
Documentation for T42 should include a detailed account of the patient's medication history, the specific drug involved, the nature of the adverse effect or poisoning, and any relevant clinical findings. It is crucial to note the context of the incident, including whether it was accidental, intentional, or due to underdosing.
