T46.0
Poisoning by, adverse effect of and underdosing of cardiac-stimulant glycosides and drugs of similar action
Clinical Classification Guidelines
Medical Intelligence & Overview
ICD-10 code T46.0 pertains to poisonings caused by cardiac-stimulant glycosides and similar drugs. These medications are often used to treat heart conditions, but overdose or adverse effects can lead to serious health issues. Recognizing the causes, symptoms, and treatment options associated with this code is vital for healthcare providers and patients alike.
Causes & Symptoms
Clinical Causes: Accidental overdose of cardiac-stimulant glycosides, such as digoxin or digitoxin Intentional misuse or suicide attempts involving these medications Underdosing leading to adverse effects due to incorrect medication administration Drug interactions that increase toxicity Incorrect self-medication or mixing of drugs without medical supervision
Key Symptoms: Nausea and vomiting Abdominal pain and diarrhea Visual disturbances, such as blurred vision or seeing yellow-green halos Confusion, dizziness, or weakness Irregular heartbeat or arrhythmias Low blood potassium levels (hypokalemia) Signs of cardiac distress, including palpitations or chest pain
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical evaluation, reviewing medication history, and laboratory tests. Blood tests are performed to measure the levels of cardiac glycosides, assess electrolyte balance (especially potassium levels), and identify any signs of cardiac arrhythmias. An electrocardiogram (ECG) may be used to detect abnormal heart rhythms associated with toxicity.
Treatment Protocols: Management of poisoning by cardiac-stimulant glycosides includes supportive care, such as monitoring vital signs, correcting electrolyte imbalances, and eliminating the toxin. Specific treatments include administering activated charcoal to reduce drug absorption if within a suitable time frame, and using medications like digoxin-specific antibody fragments (digoxin immune Fab) in severe cases. Continuous cardiac monitoring and symptomatic treatment are crucial to prevent complications. In some cases, additional interventions, such as antiarrhythmic therapy or pacing, may be necessary.
Clinical Advice & FAQs
Billing Guidance

Yes, T46.0 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report T46.0?
Clinical documentation must specify the nature of Poisoning by, adverse effect of and underdosing of cardiac-stimulant glycosides and drugs of similar action and any associated comorbidities for accurate reporting.
