2025 ICD-10-CM code T39.4X1

Accidental poisoning by antirheumatics, not elsewhere classified.

Follow the official ICD-10-CM coding guidelines for poisoning, including the use of additional codes to specify the cause of injury (Chapter 20) and any complications.Correct sequencing of codes is essential.

Modifiers may be applicable depending on the specific circumstances of the encounter, such as the place of service and the type of services provided. Consult the official coding guidelines for specific modifier rules.

Medical necessity for coding T39.4X1 is established by the presence of accidental ingestion of an antirheumatic drug, resulting in clinically significant symptoms or complications requiring medical intervention. Documentation must support the diagnosis and demonstrate the medical necessity of the treatment provided.

The clinical responsibility involves diagnosing and treating the poisoning, managing symptoms, and providing supportive care. This might include administering medication to counteract the effects of the antirheumatic drug, managing respiratory or cardiovascular issues, and providing hydration.

IMPORTANT Related codes include other specific antirheumatic poisoning codes within the T39 category (e.g., salicylate poisoning codes, if applicable).Additional codes may be needed to fully describe the injury, its cause, and any complications.

In simple words: This code is used when someone accidentally takes too much of a medicine used to treat arthritis or similar conditions, and it's not a type of poisoning already specifically listed in medical codes.It's for the first time this happens.

This code classifies accidental (unintentional) poisoning due to antirheumatic drugs that are not otherwise specified.It is an initial encounter code.The seventh character '1' signifies the initial encounter.Additional codes may be necessary to specify the manifestation of the poisoning, the underlying cause of the injury (using codes from Chapter 20), and any retained foreign bodies (using codes from Z18.-).This code excludes poisoning by glucocorticoids (T38.0-), salicylates (T39.0-), and adverse effects of antirheumatic drugs.

Example 1: A 70-year-old woman accidentally takes a double dose of her prescribed antirheumatic medication, resulting in nausea, vomiting, and dizziness. This would be coded as T39.4X1., A child accidentally ingests a quantity of an antirheumatic medication left within reach. The child presents with gastrointestinal upset. This is coded T39.4X1., An adult misinterprets the dosage instructions of their antirheumatic medicine and takes a significantly higher than prescribed amount, leading to a serious adverse reaction.This would be coded as T39.4X1.

Detailed documentation should include the specific antirheumatic drug ingested, the amount ingested, the time of ingestion, the patient's symptoms and vital signs, laboratory results (including blood tests for drug levels), treatment provided, and the patient's response to treatment.
